head
and tail
are really useful functions!
head(sort(Forbes2000$profits,decreasing=TRUE), n = 50)
If you want the first 50 rows of the data.frame, then you can use the arrange
function from plyr
to sort the data.frame
and then use head
library(plyr)
head(arrange(Forbes2000,desc(profits)), n = 50)
Notice that I wrapped profits
in a call to desc
which means it will sort in decreasing order.
To work without plyr
head(Forbes2000[order(Forbes2000$profits, decreasing= T),], n = 50)
