I have a problem whith a data.frame. I want to make a subset where some of the variables have values within ceartain limits. The variables are proportions like 1,00, 0,54, 0,00 etc. I don't get it right as R take the variables for factors.    

> ekobsub1 <- subset(ekob, PAP>0,25 & PAP<0,6 & CAP>0,1 & CAP<0,6 & FAP>0,1)
Error in `[.data.frame`(x, r, vars, drop = drop) : object "CAP" not found In addition: Warning message:
In Ops.factor(PAP, 0) : > not meaningful for factors  

> ekobn<-as.numeric(as.character(ekob[["PAP"]]))
Warning message:
NAs introduced by coercion
