Hello all!
I have a problem with R. How can I do this assemble the ELM PRP for each ua.
My data is like this:
ua ELM PRP 122C MO 5 122C BR 3 122C FA 1 122C MO 1 122D BR 7 122D MO 2
122D BR 1
and I want to obtain something like this:
ua ELM PRP 122C MO 6 122C BR 3 122C FA 1 122D BR 8 122D MO 2
Thank you very much!

Hello, To me, and maybe for others, it is beyond understanding. Please clarify.

Hi, Use ?aggregate(), ?ddply() from library(plyr) etc. dat <- read.table(text="ua ELM PRP ? 122C MO 5 ? 122C BR 3 ? 122C FA 1 ? 122C MO 1 ? 122D BR 7 ? 122D MO 2 122D BR 1",sep="",header=TRUE,stringsAsFactors=FALSE) library(plyr) ?ddply(dat,.(ua,ELM),summarize,PRP=sum(PRP)) #??? ua ELM PRP #1 122C? BR?? 3 #2 122C? FA?? 1 #3 122C? MO?? 6 #4 122D? BR?? 8 #5 122D? MO?? 2 A.K. On Tuesday, March 11, 2014 6:04 AM, catalin roibu <catalinroibu at gmail.com> wrote: Hello all! I have a problem with R.
