I am 100% positive there is a better fix for this problem and it has been
discussed. Thank you in advance for bringing it to my attention.
When upgrading to newer versions of R the old packages are not brought
along in the process. I solved that problem by creating a list of the
packages in the old version of R, importing them to the new version via a
CSV, and re-installing into the newer R directory. The script is below.
Is there a more efficient way to do this? Should I simply attempt to drag
the package folders from the old directory to the new one? Thanks
## in old version of R<2.6
write.csv(package$results, file="file path/oldpackages.csv")
##** Update R or open updated R version (R=2.60)
package.list<-read.csv(file="file path/oldpackages.csv", header=TRUE)
install.packages(c(package.list$Package)) #wait awhile and ignore errors
for base packages.
