I use this function to update my installed R packages:
updatePac <- function (checkBuilt = FALSE, ...)
update.packages(repos = "http://cran.rstudio.com";, instlib =
"/usr/local/lib/R/site-library",
checkBuilt = checkBuilt, ...)
When I type updatePac() I get:
Warning: package 'MASS' in library '/usr/lib/R/library' will not be updated
Warning: package 'Matrix' in library '/usr/lib/R/library' will not be
updated
Warning: package 'mgcv' in library '/usr/lib/R/library' will not be updated
Warning: package 'nlme' in library '/usr/lib/R/library' will not be updated
Warning: package 'nnet' in library '/usr/lib/R/library' will not be updated
Warning: package 'spatial' in library '/usr/lib/R/library' will not be
updated
Should I not try to update recommended packages in
/usr/local/lib/R/site-library on my Ubuntu system but specify
/usr/lib/R/library instead?
