[R] lda in R vs S

[Marc R. Feldesman]

I'm running a discriminant analysis in R (0.64.1) to compare it with SPlus
4.5R2.  The following command line works fine in SPlus but gives an error
in R.  I've only used R for a little while so I'm not certain here what R
(or lda) is complaining about.  The dependent variable (sarich.na[,3]) is
an alpha categorical variable, if that makes a difference.  I'm using
version VR5.3 (file name VR5.3pl037.zip).

lda.out<-lda(sarich.na[,3]~., data=sarich.na[,4:32])
Error in model.frame(formula, rownames, variables, varnames, extras,
extranames,  : invalid variable type

Is this an lda issue or an R issue?
