Import Costanzo 09 genetic interaction data into R.

Running read.table ("sgadata_costanzo2009_lenientCutoff_101120.txt", sep="\t")  will lead to some warnings. So, I import this file into Excel, visually check it and find it seems fine. I then saved it as
"sgadata_costanzo2009_lenientCutoff_101120.csv", which can be read.csv in R without warnings.
