There are three arguments given to rnorm(): The output factor is created by the division of the range of variables into 5 equal-length intervals through break argument. Scaling is supported, as well as forcing a decimal, scientific or engineering notation. Parsing takes place in three basic stages: The flat file is parsed into a rectangular matrix of strings. So, one way around this is to first convert the factor to a character vector, and then to numeric. only by their name.
