Hi: I'm using R to start learning about quantitative finance. I'm good at R, just learning finance. Some stocks on the TSX have periods in their names, usually indicating that it's a class B share, for example. The usual functions to download stock data seem to crash on these characters. Thoughts?

#load library
library(fImport)
library(quantmod)
#these work
yahooSeries(symbols='AQN')
getSymbols('AQN', src='yahoo')
#These don't
yahooSeries(symbols='ATD.B')
getSymbols('ATD.B', src='yahoo')
