Hi Nellie,
hope I got you right. I guess you want something like that.
for (i in 1:7) {
oneOfNelliesArray<- eval(parse(text=paste("grp",i, sep="")))
anyFunction(oneOfNelliesArray)
}
Paste() just returns you a string. But you want R to evaluate the
expression. So you have to parse it and tell R to evaluate it.
But using get() is so much simpler and safer.
