How do I select all but the first two rows from e.g. the mtcars dataset?
I know that I can write no_mazda <- mtcars[3:32]
, which does work as long as I know the number of rows. But when I don't know the number of rows I need to write e.g. no_mazda <- mtcars[3:nrow(mtcars)]
which of cause also works, but:
Does R provide a smarter syntax than an expression that includes mtcars
twice?
I prefer using tail
with negative values for n
:
tail(mtcars,-2)
