I ran reshape package and got the following error messages.


> library(reshape)
Loading required package: plyr
Error in get(Info[i, 1], envir = env) :
cannot allocate memory block of size 2.3 Gb
Error: package ‘plyr’ could not be loaded
> mdata <- melt(mydata, id=c("id","time"))
Error: could not find function "melt"


Do not quite understand where it went wrong.
