Here is one way with an example:
datas=data.frame(x=1:3,A=1:3,A=1:3)
names(datas)=c("x","A","A")
datas
datas=datas[,names(datas)!="A",drop=FALSE]
datas

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
