Re: [Rd] install packages with missing pkg argument
Indeed it's a RStudio issue as diagnosed by Hugh, and is still an issue with the latest version.

I believe having the function work as advertised with a proper missing argument, and having it do nothing silently when the argument is of length zero, would make more sense.

Re: [Rd] install packages with missing pkg argument
Indeed Hugh, apologies for the oversight, I've reported this to Rstudio, as I believe it is problematic to get an irrelevant help file when calling `?install.packages`. https://github.com/rstudio/rstudio/issues/5154 Best regards, Antoine Le lun. 29 juil. 2019 à 13:59, Hugh Parsonage a écrit : > Are you running that command in RStudio?

Re: [Rd] install packages with missing pkg argument
Are you running that command in RStudio? And do you get the documented results when you run utils::install.packages() rather than just install.packages() If yes, then the function is likely working as advertised and you've mixed up the R and RStudio versions On 29/07/2019, Ant F wrote: > Dear all, > > The help for `?install.packages` decribes, in the `pkg` argument > description : > >> If this is missing, a listbox of available packages is presented where > possible in an interactive R session. > > In fact running it with a missing argument triggers an error : > > install.packages() >> Error in install.packages : argument "pkgs" is missing, with no default > > What however doesn't trigger an error is callinginstall.packages on a zero > length character : > > install.packages(character(0)) > > On my colleague's R 3.5.1 windows installation it shows the listbox of > available packages, on my 3.6.0 installation it pauses for a couple seconds > and doesn't do anything. > > A character vector of length zero is what you get when you compute an empty > `setdiff` or `intersection`, so it was very surprising to us to see > something popup where we were expecting a vector of missing packages to be > installed (or none if there was no missing package). > > I believe having the function work as advertised with a proper missing > argument, and having it do nothing silently when the argument is of length > zero, would make more sense. > > Best regards, > > Antoine > > [[alternative HTML version deleted]] > > __ > R-devel@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-devel > __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
[Rd] install packages with missing pkg argument
Dear all, The help for `?install.packages` decribes, in the `pkg` argument description : > If this is missing, a listbox of available packages is presented where possible in an interactive R session.
