Re: [R] grab values in R
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.

[R] grab values in R
