R help - May 2010 - Removing columns from data frame referenced by column index

Can you suggest me any way to remove a column of a data frame by the column
number,not by the column name.

Thanks,

data(airquality)
head(airquality)
Suppose you want to remove the 1st and the 3rd column this will do
 airquality[,-c(1,3)]
