Hi there,
I've got a set of 10 numeric variables called Mood1 to Mood10 in a dataset
called mood. I'm trying to create a set of 10 new variables called m1 to m10
so that m1=Mood1*1, m2=Mood2*2, etc to m10=Mood10*10
Trawling through the internet, I eventually tried the following code:
for (i in 1:10){
assign(x=paste0("mood$m",i),
value=paste0("mood$Mood",i)*i,
envir=.GlobalEnv)
}
Indexing works via
mood[[paste0("Mood", i)]]
However, assignment to separate objects is typically a bad idea, just
aollect them in another data.frame or list.

unfortunately this doesn't work as it seems the paste0 function returns a list
object that only contains the vector's name and not the vector itself.
Hope someone can help...
