lm(height ~ ., data=X) works fine. However nnn <- "height" ; lm(nnn ~ . ,data=X) fails
How do I write such a formula, which depends on the value of a string variable like nnn above? A typical application might be a program that takes a data frame containing only numerical data, and figures out which of the columns can be best predicted from all the other columns.
