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 ))) > View this message in context: > http://r.789695.n4.nabble.com/decimal-separator-from-comma-to-dot-tp4673414p4673433.html > Sent from the R help mailing list archive at Nabble.com.
