I have a list called cols with column names in it:
cols <- c('Column1','Column2','Column3')
I'd like to reproduce this command, but with a call to the list:
data.frame(Column1=rnorm(10))
Here's what happens when I try it:
> data.frame(cols[1]=rnorm(10))
Error: unexpected '=' in "data.frame(I(cols[1])="
The same thing happens if I wrap cols[1] in I() or eval().
How can I feed that item from the vector into the data.frame() command?
