无法在DSX Desktop中安装新的R包

Question

I've just installed DSX Desktop with RStudio. I'm unable to load new packages, eg lubridate , and get the error below. If I check for package updates, I get the message "all packages are up-to-date", but the error below suggests it needs a newer version of Rcpp .

installing to /user-home/_global_/R/lubridate/libs
** R
** data
*** moving datasets to lazyload DB
** inst
** preparing package for lazy loading
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  namespace ‘Rcpp’ 0.12.9.2 is already loaded, but >= 0.12.13 is required
ERROR: lazy loading failed for package ‘lubridate’
* removing ‘/user-home/_global_/R/lubridate’
Warning in install.packages :
  installation of package ‘lubridate’ had non-zero exit status

The downloaded source packages are in
  ‘/tmp/RtmpIV4HWl/downloaded_packages’

I tried install.packages("Rcpp") which returned the message:

Error in unloadNamespace(pkg_name) : 
  namespace ‘Rcpp’ is imported by ‘httpuv’, ‘reshape2’, ‘tidyr’, ‘bindrcpp’, ‘tibble’, ‘htmltools’, ‘dplyr’, ‘plyr’ so cannot be unloaded

If I try remove.packages("Rcpp") or removing the packages above, I get the following message, and they remain in the Packages view.

Removing package from ‘/user-home/_global_/R’
(as ‘lib’ is unspecified)
Error in remove.packages : there is no package called ‘Rcpp’

Any advice please on how to proceed?

Answer 1

There seems to be a fundamental problem with RStudio. I encountered exactly the same problems you describe with the latest version (1.1.442). The problems are:

1. Packages viewed as out-of-date go into a loop when installing with a repeated error dialog box appearing.
2. The package version check refers out-of-date packages and will not install the current package versions showing on CRAN. This is due to RStudio pointing at a MRAN mirror that has old updates. This means that all packages stored there are out of date. You can see when the packages on MRAN were last updated here .
3. Removal of other packages (eg dependencies) doesn't work properly, and manual deletion of the folders doesn't solve the problem.

Inside Tools , Global options , Packages there is the ability to specify the mirror that should be used for package management. This doesn't seem to work.

I fixed my problem by going into R and performing a package update inside that. RStudio now uses the updated packages.

I have contacted RStudio about this and received the reply that they don't provide support for free versions of RStudio.

tl;dr: RStudio appears to be broken for updating packages. Use R itself for updates.

I was getting this error: Windows 7, update.packages problem: “unable to move temporary installation”? Which I think was due to my antivirus, but not sure. MRAN version was 3.3.1 and this is what I would do to fix this error everytime I opened R-Studio and needed to install:

trace(utils:::unpackPkgZip, edit=TRUE)
# Edit line 142 - change Sys.sleep(2.5)

I was still having versioning issues with tidyverse, so looked around and decided to install the latest MRAN from Microsoft and that fixed all of my R-Studio versioning issues and install inssues. I had other issues where I was doing a work.
