[R] Converting dollar value (factors) to numeric

[Ruihong Huang]

If you use Linux, we can simply use "sed" (in Linux terminal, NOT R) to 
delete all leading '$' from the file "test.dat" by

$ sed -e 's/\$//g' test.dat > newdata.dat

And now R will read all this dollar as numeric.


Bests,
Ruihong
