Installing R on Hortonworks Sandbox issues

Hi everybody,

I’m experiencing some troubles when I try to install R dependencies with the command :

install.packages( c(“Rcpp”,”RJSONIO”,”bitops”,”digest”,”functional”,”itertools”,”reshape2″,”stringr”,”plyr”,”caTools”),repos=’http://cran.revolutionanalytics.com’)

packages are downloaded but then all I get are the messages

/usr/lib64/R/bin/R: line 8: uname: command not found
/usr/lib64/R/bin/R: line 143: exec: sh: not found

repeated as many times as the number of packages I am trying to install.

I am using R version 3.2.2, rstudio-server 0.99.489  in Hortonworks Sandbox with hadoop 2.3 (Oracle Virtualbox).

Do you have any suggestions?

Thanks for your help.
