Install-Package is not recognized as an internal or external command, operable program or batch file

'C:\Program' is not recognized as an internal or external command, operable program or batch file. Warning in install.packages : running command '"C:/Program Files/R/R-3.2.0/bin/x64/R" CMD INSTALL -l "C:\Users\XXXX\Documents\R\win-library\3.2" C:\Users\XXXX\AppData\Local\Temp\XXXX/downloaded_packages/DT_0.1.tar.gz' had status 1 Warning in install.packages : installation of package ‘DT’ had non-zero exit status The downloaded source packages are in ‘C:\Users\XXXX\AppData\Local\Temp\XXXX\downloaded_packages’

Because of that it is not possible to install DT. At the same time shiny has made renderDataTable depreciated and wants it imported from DT, so it makes this feature also not available from shiny.

It seems that there is some kind of brackets or slashes in path issue in the installation code.

setx PATH “%PATH%;C:\Python38-32\Scripts;C:\Python38-32”

In the above command C:\Python38-32 is our Python installation directory.
