How to list all installed R-packages
I don’t use R, and nor I do know much about it. However, I maintain R’s installation on linux machines at work. Today, I learned a new trick to list all installed R-packages. Here it is: ip = as.data.frame(installed.packages()[,c(1,3:4)]) ip = ip[is.na(ip$Priority),1:2,drop=FALSE] ip And here is the sample output: Type 'license()' or 'licence()' for distribution details.

Type 'contributors()' for more information and 'citation()' on how to cite R or R packages in publications. Type 'demo()' for some demos, 'help()' for on-line help, or 'help.start()' for an HTML browser interface to help. Type 'q()' to quit R. > ip = as.data.frame(installed.packages()[,c(1,3:4)]) > ip = ip[is.na(ip$Priority),1:2,drop=FALSE] > ip Package Version akima akima 0.5-12 alr3 alr3 2.0.5 BRugs BRugs 0.8-6 car car 2.1-2 coda coda 0.18-1 colorspace colorspace 1.2-6 DEoptimR DEoptimR 1.0-5 dichromat dichromat 2.0-0 digest digest 0.6.9 distillery distillery 1.0-2 extRemes extRemes 2.0-7 fields fields 8.4-1 ...
