Fairly new at this.
Trying to create a conditional density plot.
cdplot(status~harvd.l,data=phy)
Error in cdplot.formula(status~harvd.l,data=phy):
dependent variable should be a factor
What does this error mean? Status is a binary response of infestation (0/1)
Probably status is a numerical variable rather than a factor**. Try
print(is.factor(phy$status)) and if that is FALSE then
phy$status <- factor(phy$status, labels=c("N", "Y"))
cdplot(status~harvd.l,data=phy)
Hope this helps a little.

and harvd.l is the log of timber harvest density per catchment.
Thanks.
