Publish your work with R Markdown. R is a terrific tool for telling stories with graphics and data, but sometimes you need words too. R Markdown weaves together narrative text and code to produce elegantly formatted reports, papers, books, slides and more. Garrett Grolemund will give you a personal R Markdown tour with his Get Started With R Markdown video, or you can choose your own path through the wonders of R Markdown at rmarkdown.rstudio.com. Bookmark R Markdown: The Definitive Guide (2018) as you work too; it provides a great overview of what is possible within the R Markdown family of packages.
I am joining this thread because I am having the same issue. The arrows were working fine until I downloaded RStudio 2023.06.0+421. I am working on a MacBook Pro using OS Monterey 12.6 and R 4.2.0. Like @jahnavi I closed everything and restarted RStudio, reinstalled RStudio, and ensured everything was updated.
If it's helpful for anyone on this post, the link shared above has this workaround:
rstudioapi::writeRStudioPreference("data_viewer_max_columns", 1000L)
A word of caution around it: Make sure that the value is no larger than the number of columns. If you do, then the >> will become clickable, and clicking on it could cause the application to freeze.
Hopefully this issue gets fixed, it's incredibly annoying.
I'm unable to get R to install binary packages from packagemanager.rstudio.com on a CentOS Linux server. R will always fetch the source and compile it instead of getting the binary when I try to install a package.
