I am trying to install several packages on the RStudio-hosted Shiny Server, but these packages run with at least R version 3.0.0. A possible solution that I found on the Internet:
download.file('http://cran.rstudio.com/src/contrib/Archive/devtools/devtools_1.1.tar.gz', destfile='devtools_1.1.tar.gz')
install.packages('devtools_1.1.tar.gz', type='source', repos=NULL)
unlink('devtools_1.1.tar.gz')
does not work and I get the following error:
Warning in install.packages : package ‘devtools_1.1.tar.gz’ is not available (for R version 2.15.3)
How could I modify this code in such a way that I am able to install the devtools package?
Thank you in advance!
