I just need to go back to the basics and learn how to add "rows" to data.frames. I am sure it won't be hard, its just my personal learning curve with several new data types (factors, tables, data.frames vs vectors, lists, arrays which I am more familiar with). For example, yesterday I tried max(myFactor) and it gave me an error (something like "must be a vector"), even though to my naive way of thinking myFactor clearly had a numeric max.
