I'm working on an R package in C and can't seem to get the same level
information about a factor that the R console displays.
If I define a factor as:
lvls <- factor(c('red','blue','blue','green','red'), c('blue','green','red'),
ordered=TRUE)
When I get the "levels" attribute in C, I get back the the first vector, not
the second. If I run attr(lvls,"levels") in R, I get back the second vector.
There are no attributes besides class and levels, so how do I get the list of
levels in the correct order?
Thanks
