Reading numeric as factor can have many causes from weird formating to some nonumeric characters. If you can not clean it when making *.csv file you shall either adopt reading function by using different options
or if it does not help, you can either polish your values by some regular expressions.
For simple changing factor values to numeric you shall use
fb <- as.numeric(as.character(fb))
But all values which are not transferable to numeric will be changed to NA
