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).
Error in model.frame(formula, rownames, variables, varnames, extras,
extranames, : invalid variable type
Is this an lda issue or an R issue?
