Hi,
I have a dataset where the results are coded ("yes", "no") We want to
do some machine learning with SVM to predict the "yes" outcome
My problem is that if I just use the as.factor function to convert, then
it reverses the levels.
----------------------
x <- c("no", "no", "no", "yes", "yes", "no", "no")
as.factor(x)
[1] no no no yes yes no no
Levels: no yes
You want to use ?factor, not ?as.factor. Then you can use the "levels"
argument.
factor(x, levels = c("yes", "no"))
Also see ?relevel.
