foo <- "https://cran.r-project.org/src/contrib/archive/ggvis/ggvis_0.4.2.tar.gz" install.packages(foo, repos=null, type="source") 

based on post: installing older version of r package

this result in console. have replaced name of company , user in directories "company" , "user" respectively discretion.
