I am trying to install the dplyr and stringr package but i get the below error

Warning in install.packages :
  downloaded length 139264 != reported length 3227450
Warning in install.packages :
  error 1 in extracting from zip file
Warning in install.packages :
  cannot open compressed file 'dplyr/DESCRIPTION', probable reason 'No such file or directory'

I tried different installation commands like

install.packages(“dplyr”)
install.packages(“dplyr”,  repos="http://cran.us.r-project.org")
install.packages(“dplyr”,  repos="http://cran.us.r-project.org",type="win.binary")

Till yesterday, I was able to install this package successfully. But today it is throwing this error.

This error happens with other packages like stringr as well. I tried chaging CRAN mirrors as well but still no help

Can help please?

  • Have you tried downloading the package source files instead? [dplyr_0.8.5.tar.gz](https://cran.r-project.org/web/packages/dplyr/index.html ) – SidharthMacherla Apr 14 '20 at 08:43
  • Are you asking me to download this zip file and load them in my workspace as a local package? – The Great Apr 14 '20 at 08:46
  • But isn't there a way to fix this issue? Meaning by using install.packages()? – The Great Apr 14 '20 at 08:57
  • This is likely caused by something outside of R: your virus checker may be interfering with the download, for example. @SidharthMacherla's suggestion may let you work around that. – user2554330 Apr 14 '20 at 10:01
  • @user2554330 - But it was working fine yesterday. – The Great Apr 14 '20 at 10:09
  • But the same works in R Gui. Meaning install.packages work in R Gui. But when I use them in RStudio, I get this error. Is it possible that I install packages using R gui and load the libraries in RStudio. Will this setup work? – The Great Apr 14 '20 at 10:11
  • Try this [solution](https://stackoverflow.com/a/69706249/4502415). It worked out for me. – Mohamed Ismaiel Ahmed Oct 27 '21 at 09:12
  • Are you running code with smart quotes around `dplyr`? – Hugh Oct 27 '21 at 09:16

I have downloaded a R package and installed from local files. Next I tried to install a package, with many imports, through Install package(s), I could not install. I closed R and restarted R, now I am able to install packages, with many imports. Rahul, R user.

This error typically happens because R cannot access the default directory for installing the packages. This error is a system-related error. Try this solution. It worked out for me. I changed the default installation directory in the environment variables and it worked smoothly.
