Minor modification:
fff <- function(x) as.numeric(chartr(",", ".", x))
BX <- sapply(AX, fff)
Or this keeps the original data frame:
AX[, 1:2] <- sapply(AX[, 1:2], fff)

Subject: Re: [R] changing "," to "." in data.frame
And as follow up,
fff<-function(x) gsub(",", ".", x)
BX <- apply(apply(AX, 2, fff), 2, as.numeric)
this seems to be easier.
Cheers
