Dear all,
I would like to know if there is an easy to transform a vector of strings to
a vector of integers.
Ex:
("ab","ab","bb","cat","cat","ab") will be
(1, 1, 2, 3, 3, 1)
Hi Naira,
It's not all that hard...
newfactor<-as.factor(c("ab","ab","bb","cat","cat","ab"))
newfactor
[1] ab ab bb cat cat ab
Levels: ab bb cat
as.numeric(newfactor)
[1] 1 1 2 3 3 1
