@RaghavBatra : So the fix will be a little more involved than this. If you try installing your branch, you will see that the documentation will now be incorrect for DataFrame.replace. I think you might have to define replace in the Series class and add custom documentation there (unless I'm forgetting some doc-trick @jreback ?)

Hey this looks like more work than I thought. Maybe later and thanks for your help!
