Dear All,

please excuse me for insisting from a previous post (Error with R package RontoTools regarding administrator issues downloading updated KEGG data), but because i dont have any significant experience in any related issues, i would like to ask to general questions about the installation of R packages:

1) as i want to remove a specific R package: because when i updated in  R 3.2.2 i kept also my previous r R version-but from Rstudio i run only the latest version- should i remove manually the package,

or use something like: remove.packages("ROntoTools") # the specific package ??

2) Secondly, to reinstall the above package again, but using a custom library path(because with the default biocLite i have problems in dowloading data-"permision denied" etc..-, could i use some argument with biocLite() specifying this ?

I searched also some forums and found the function: 

.libPaths() which by default returns : .libPaths()

[1] "C:/Program Files/R/R-3.2.2/library"

Thus, could i use this argument specifying a different location for installing this specific package, like my default working directory: 

"C:/Users/Efstathios/Documents" ??

Any help or suggestions would be essential !!
