I have a number of columns
that I would like to remove from a data frame. I know that we can delete them
individually using something
like:
df$x <-
NULL
But I was hoping
to do this with fewer commands.
Also, I know
that I could drop columns using integer indexing like
this:
df <- df[
-c(1, 3:6, 12) ]
But I
am concerned that the relative position of my variables may
change.
Given how powerful R is, I figured there
might be a better way than dropping each column one by one.
