Please do read the Posting Guide. You are asked to include context. In this case including the citation to the Archive-stored code would have been courteous as well;

 #### not recommended ####
mysub <- function(x) {sub(",",".",x)}
mydata <- (apply(kk, 2, mysub ))
kk1 <- data.frame(apply(mydata, 2, as.numeric))


I would have expected that as.numeric(as.character(x)) to be needed rather than the "factor-mangling" as.numeric() strategy. This IS in the FAQ,
	7.10 How do I convert factors to numeric?
  In this case you only have a single column that is affected so:

   df$POT_TX <- as.numeric(as.character( sub(",", ".", df$POT_TX )))

Nabble tries very hard to confuse its users about the nature of Rhelp. It even omits the message below when posting content.

So, maxbre,  please do step up to your responsibilities. You've been posting to rhelp for a year and have 58 posts per the Markmail search engine.
