I am trying to install the R-ARCGIS toolbox but this message appears everytime I click on the install button: Link failed. Completed script InstallBindings... Failed to execute (InstallBindings).
Saving URL to 'c:\users\tcronin\appdata\local\temp\arc5412\tmpijjw4k\arcgisbinding_1.0.0.111.zip' installing to library 'C:/Program Files/R/R-3.1.2/library' R command returned non-zero exit status.
