Executing R commands in Bash script?

Question

From a bash script would I like to execute these R commands

install.packages('knitr', dependencies = TRUE)
install.packages("xlsx", dependencies="Depends")
install.packages("xtable")

One way would be to put them in a R file, then execute that, but I would prefer not to do that.

Can these commands be executed directly from a Bash script?

Try Rscript -e "..." (read Rscript man for details) or google for littler — jangorecki

Just use #!/usr/bin/env Rscript like you would use #!/bin/bash in an executable shell script. — nrussell

apt-get -y install littler

echo 'install.packages("knitr", dependencies = TRUE, repos="http://cran.rstudio.com/")' | r

R -e can also be used.
