[R] How to read percentage and currency data?

[Hrishi Mittal]

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.
