I'd like to subset a df within a function, and use select for choosing the variable. Something like (simplified example):
mydf <- data.frame(a= 0:9, b= 10:19)
ttt <- function(vv) {
tmpdf <- subset(mydf, select= vv)
mean(tmpdf$vv)
}ttt(mydf$b)
But this is not the correct way. Any help? Thanks in advance
Juli
