[R] Problems faced with Levene Test using R

[Philip Wong]

Hello everyone, I'm trying to build Levene's test.  The below command is what
I used to do the test, I also included the error it prompts up and some data
example that I used when trying to build the test.  Can someone please tell
me what did I do wrong? thanks in advance!

> res=lm(as.matrix(xx$B_Leth)~as.factor(xx$Wt_Leth))
> resid=abs(res$residuals)
> lev=lm(resid~as.factor(xx$Wt_Leth))
> mvlev=manova(lev)
Error in manova(lev) : need multiple response
