Given an arbitrary data frame, it is easy to exclude a column given its index:
df[,-2]. How to do the same thing given the column name? A naive attempt
df[,-"name"] did not work :)

Hi,
This piece of code does the trick. Most important is the which() command:
df = data.frame(a = runif(10), b = runif(10))
df[,-which(names(df) == "a")]
cheers,
Paul
