Since a name is a single value character, it is later coerced to a single-level factor and causes the error. Error in `contrasts<-` (`*tmp*`, value = contr.funs [1 + isOF [nn]]) : contrasts can be applied only to factors with 2 or more levels. Loop through a character vector to use in a function.

When fitting models using lm and glm, sometimes you can get a mystery error that says that "contrasts can be applied only to factors with 2 or more levels". This function helps trouble shoot this error when it appears by helping to find the problematic errors. Amazing details are found in the StackOverflow where this function comes from.
