[R] cv.lm syntax error

[agent dunham]

Yea, sorry,  that's what I mean, and  v1,...,v5 and factor have the same
length, that's why I don't understand the error

> dfmod.1 <- data.frame(v1,v2,v3,v4, v5,factor)

> CVlm(df= dfmod.1, form.lm = formula(v1 ~ v2+v3+ v4+ v5+ factor), m=3,
> seed=29, plotit=TRUE, printit =TRUE)

Error en `[.data.frame`(df, , ynam) : undefined columns selected 

Thanks,
