Hi all,
I am having a bit of trouble using the levels() function.
I have a factor with many elements, and when I use the function levels() to
extract the list of unique elements, some of the elements returned are not

vec1- factor(1:5,levels=1:10)
vec1
#[1] 1 2 3 4 5
#Levels: 1 2 3 4 5 6 7 8 9 10
vec2-droplevels(vec1)
levels(vec2)
#[1] 1 2 3 4 5
vec2
#[1] 1 2 3 4 5
#Levels: 1 2 3 4 5
