Dear R-experts, I am installing new libraries using install.packages("ggplot2",dependencies=T). But I perceive that many dependencies are already installed. As I am using a low-band internet, how can avoid reinstall installed libraries? cheers milton [[alternative HTML version deleted]]

It looks like your concern is already taken care of. -steve -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact

Why do you think are you talking about the function install.packages() ???? ^^^^^^^^ --- To answer the question you did want to ask: Do not be afraid: Depedencies are only installed when needed, i.e., no package will be downloaded and installed if it already is there.
