Hi! My regression is lm(Y ~ A + B + C + D + E + F + G), where each covariate "A--G" is of the kind "as.factor(column of the dataframe)". I receive an error for the first explanatory variable "A": Error in column of the dataframe: wrong number of dimensions. What does it mean? -- View this message in context: http://r.789695.n4.nabble.com/lm-regression-tp3060123p3060123.html Sent from the R help mailing list archive at Nabble.com.
