Thanks Ista, that's sort of what I'm doing at the moment. But my problem is that I don't always know if the data has such symbols or signs in them. I can do a gsub on the entire dataset but I also need to preserve the currency signs to deal with multiple columns with different currencies. Doing string replacement on all of them would be messy. I would also have to save the currencies as an index in another vector to preserve the meaning of the data. So I was hoping there is a more elegant way to do it, considering the wide usage of R in the finance world.
