lm(height ~ ., data=X)
nnn <- "height" ; lm(nnn ~ . ,data=X)
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.
