Well, this is wrong. Try:
levels(factorA) <- c("lv1","lv2","lv3")
> factorA
[1] 2 2 3 3 4 4 3 4 2 2
attr(,"levels")
[1]
Dear all,
According to the post I was trying:
factorA = c(2,2,3,3,4,4,3,4,2,2)
levels(factorA <- c("lv1","lv2","lv3") )
But this returns NULL and doesn't change factor names.
Actually, my factor is included in a data.frame, so I also tried:
levels(df$factorA)[levels(df$factorA)=="2"] <-

t because it used non-numeric level names.)
I hope this helps,

Hi all,

Hi Saiwing,
If all you are asking is how to rename a factor vector, the easiest way
would be to use:
levels(Loblolly$Seed) <- c( a vector of level names you would like to use
for the factor - separated by commas)
If you are asking how to make your output look better, I am not sure I have
an idea (
mes.)
I hope this helps,
John

Hi all,
I have a pretty basic question about categorical variables but I can't
seem to be able to find answer so I am hoping someone here can help. I
found that if the factor names are all in numbers, fitting the model
in lm would return labels that are not very recognizable.
