Changes in version 1.0-0 - Release of version 1.0-0 to accompany the publication in The R Journal (see below). - The functions ohat() and gcode() for linking from CRAN Task Views to Omegahat and Google Code have been removed from the vignette. Omegahat.net is defunct and Google Code has been archived and inactive for 10 years now. - Code repository for the R package changed from R-Forge to Codeberg at: https://codeberg.org/zeileis/ctv/ - Added basic altdoc page with overview and documentation at: https://zeileis.codeberg.page/ctv/ - Enable working with ctv and multiple repositories in getOption("repos") (reported and fixed by Henrik Bengtsson, #1 @hb). Changes in version 0.9-8 (2026-04-15) - The citation("ctv") paper has been published: Zeileis A, Bivand R, Eddelbuettel D, Hornik K, Piaskowski J, Vialaneix N (2025). "The CRAN Task View Initiative." The R Journal, 17(2), 4-14. doi:10.32614/RJ-2025-011. - Improve HTML output for CRAN Task Views: No trailing slashes in void elements such as
or . Set language in tags. Changes in version 0.9-7 (2025-07-28) - Check for rmarkdown::pandoc_available() before calling rmarkdown::pandoc_convert() (suggested by Michael Dewey). - In available.views() better avoid errors when the repos does not provide any task views. Changes in version 0.9-6 (2024-11-26) - Add header information about canonical CRAN URLs for all task views as . Changes in version 0.9-5 (2023-05-30) - New citation("ctv"): Zeileis A, Bivand R, Eddelbuettel D, Hornik K, Vialaneix N (2023). "CRAN Task Views: The Next Generation." arXiv 2305.17573, arXiv.org E-Print Archive. doi:10.48550/arXiv.2305.17573. - For CRAN web pages produce pkgname for packages on CRAN, Bioconductor, GitHub, R-Forge, OmegaHat, etc., where the custom classes yield custom colors in the CRAN style. - Updated Bioconductor URLs from bioc("") tags to https://www.bioconductor.org/packages/. Changes in version 0.9-4 (2022-11-06) - Improved and extended documentation for CRAN task view maintainers in vignette("ctv-howto", package = "ctv"). - CRAN information about packages and archivals is loaded from local files (rather than downloaded) if run on CRAN. Also, it is preserved between subsequent runs of read.ctv(..., cran = TRUE) (and hence also ctv2html(..., cran = TRUE) etc.). - read.ctv(..., cran = TRUE) now warns if a pkg() is not available from CRAN. - Add Facebook OpenGraph and Twitter tags in task view HTML pages. - New convenience function ctv() that obtains a single ctv object with information about a certain task view on CRAN with a given name. - New list element $citation in ctv objects containing a citation object inheriting from bibentry with information on how to cite a task view. - The auxiliary view() function gained a second argument so that specific sections in other task views can be referenced, e.g., view("Econometrics", "Instrumental variables"). - Fix typo in task view header it should be install.views() and update.views() rather than install.packages() and update.packages(). - Fix detection of "core" packages if the priority is not declared in the first pkg() call but in subsequent calls. - Improve HTML5 output from ctv2html(). Changes in version 0.9-3 (2022-03-27) - Enhance handling of archived packages on CRAN when read.ctv(..., cran = TRUE) and ctv2html(..., cran = TRUE). - Further improvements in ctv2html(): Generate HTML5 with pandoc now, improve preservation of link breaks (--wrap=preserve). Changes in version 0.9-2 (2022-03-02) - Bug fix in read.ctv() when pkg(..., priority = "core") is used more than once on the same package name (reported by Rocio Joo). - Sorting the package list is done ignoring the case now. - Various improvements in ctv2html(): Include explicit citation in header table, include instructions for contributions and installation (if cran = TRUE), more compact layout of package list, handle task views without links section correctly. Changes in version 0.9-1 (2021-12-17) - Bug fix in read.ctv(file) when file is actually a full path and not just the name of file in the local working directory. - Make all examples of read.ctv() conditional on knitr and rmarkdown being available (or xml2 being available in case of the legacy XML format). Changes in version 0.9-0 (2021-12-14) - Various substantial changes to support the launch of the CRAN Task View Initiative: Development and maintenance of CRAN task views will be overseen by a team of CRAN Task View Editors who review and approve new task views and help maintainers with onbaording. Infrastructure for this is moved from R-Forge to GitHub (with only the maintenance of the ctv package remaining on R-Forge). The file format for task view files changes from the old XML-based format to a new leaner R-Markdown based format. - For the R package ctv itself there is now a pkgdown web page at: https://ctv.R-Forge.R-project.org/. - The vignette("ctv-howto", package = "ctv") has been completely rewritten, now describing the new R/Markdown-based format. (The vignette itself is now in HTML rather than in PDF format.) - For processing the legacy XML-based files the xml2 package is used now (instead of the XML package). - Added tag in the legacy XML format to add hyperlinks to DOIs, e.g., 10.18637/jss.v067.i01 will be turned into https://doi.org/10.18637/jss.v067.i01. - The tag now explicitly resolves to https://code.google.com/archive/ (including the archive/ part) as Google Code has been archived in 2016. Changes in version 0.8-5 (2018-05-17) - The ctv-server tools now generate a somewhat more verbose index.html page that explains what task views are and how they could be extended. Changes in version 0.8-4 (2018-01-18) - tag can now be used to refer to projects on GitHub using markup like user/project. - To support older versions of R (up to R 3.4.3), the server-side tools now explicitly use saveRDS(..., version = 2) to store task view information. Changes in version 0.8-3 (2017-10-07) - packages are now at Omegahat.net rather than Omegahat.org. Changes in version 0.8-2 (2016-09-15) - There is a new optional tag that can be used to display an official task view URL (and insert it into the metainformation tags). For CRAN task views the official URL is used by default. Changes in version 0.8-1 (2015-01-10) - Bug fix in check_ctv_packages(): Packages in but not in were not computed correctly. Changes in version 0.8-0 (2014-07-31) - HTML generation improved. Now XHTML 1.0 is produced with both DublinCore and HighWire Press metainformation tags. Changes in version 0.7-9 (2014-01-05) -
tags are preserved as such in the section. Changes in version 0.7-8 (2013-04-12) - Use system.file() instead of .find.package() in vignette. Changes in version 0.7-7 (2013-04-05) - Use system.file() instead of .find.package() in ?read.ctv. Changes in version 0.7-6 (2013-01-29) - New function check_ctv_packages() for maintainers of CRAN task views. This checks whether and are consistent and whether all packages are actually available in the repository. Changes in version 0.7-5 (2013-01-11) - Package depends on R >= 2.13.0 now in order to use only saveRDS()/readRDS() and not .saveRDS()/.readRDS(). Changes in version 0.7-4 (2011-12-22) - update.views() gains a filter argument passed to available.packages(), so that the packages can be filtered with respect to operating system type or free and open-source license etc. Changes in version 0.7-3 (2011-07-27) - saveRDS() instead of .saveRDS() is now used in the server-side tools if available. Changes in version 0.7-2 (2011-04-17) - Avoid usage of ≪ in Cluster.ctv because it is not processed correctly on all platforms - Further improvement to available.views() which now uses readRDS() if available. Changes in version 0.7-1 (2011-04-16) - Fixed available.views() for R 2.13.0 as the underlying .readRDS() needed to be changed. Changes in version 0.7-0 (2010-11-14) - Added download.views() function (as suggested by Peter Ruckdeschel). - Restructured internals of install.views() and update.views() so that all three functions can use the same code for determining the list of packages that is going to be installed/updated/downloaded. Changes in version 0.6-0 (2010-06-01) - update.views() was updated reflecting that bundles are not supported anymore. Changes in version 0.5-6 (2009-11-19) - Modified code to avoid non-standard evaluation in subset(). Changes in version 0.5-5 - Simplified printing of warnings (with useFancyQuotes = FALSE). Changes in version 0.5-4 (2009-09-30) - grep(..., extended = FALSE) replaced by the more appropriate grep(..., fixed = TRUE). Changes in version 0.5-3 (2009-07-22) - The R-Forge links created from are now forced to be in lower case. Changes in version 0.5-2 (2009-06-03) - Minor changes to improve generation of tidy HTML. Changes in version 0.5-1 (2009-02-12) - In .ctv files a new tag is allowed: for links to Omegahat projects. - The tags and replace the previous and , respectively, in order to be more consistent with the terminology used in the CRAN Web pages. - Further improvements of server-side tools in order to provide tidy XHTML code. - The default style file included in the server-side tools is now CRAN_web.css (rather than R.css). Changes in version 0.5-0 (2009-02-08) - Improved server-side tools: read.ctv() and ctv2html() now try harder to provide tidy XHTML code. Changes in version 0.4-9 (2009-02-05) - Added CITATION file. Changes in version 0.4-8 (2009-01-23) - New tag. Changes in version 0.4-7 (2008-12-09) - Removed \itemize in .Rd files for new R-devel. Changes in version 0.4-6 (2008-11-06) - Changed interface of install.views() and update.views(): Argument dependencies = TRUE has been removed (but can still be specified through ...). Hence, by default, the defaults of install.packages() are inherited. However, it is still possible to get the prior behaviour by setting dependencies explicitly in install.views()/update.views(). Changes in version 0.4-5 (2008-09-18) - Enhanced support for R-Forge and Bioconductor links (new tag, similar to ). Changes in version 0.4-4 (2008-09-03) - Enhanced UTF-8 support. Changes in version 0.4-3 (2008-06-05) - Enabled UTF-8 support for character fields in CTV files. Changes in version 0.4-2 (2008-04-03) - Updated vignette to better reflect the latest changes. Changes in version 0.4-1 (2008-04-03) - Added new tags and for CTV files. Changes in version 0.4-0 (2008-02-16) - New function update.views() which only installs the packages from a view that are not installed or not up-to-date. - Added infrastructure for view version/date and contact e-mail address of the maintainer. - Adapted the server-side tools to the new web-structure of CRAN.
