Hi, I have a data frame datas with half of the columns with the same name "A". I want to delete all those columns from the data frame so here is what I did: datas$A<- NULL The problem is that it deleted only one column, I would have to do it as many times as there are "A" columns. Is there a way to do it in one time? thank you ----- Anna Lippel
