changing "," to "." in data.frame

tring
Dear friends - I have a data.frame with "," instead of "." and found the
discussion

http://r.789695.n4.nabble.com/How-to-replace-all-commas-with-semicolon-in-a-string-tt4721187.html#a4721192

so copying the code of Ulrik(I hope:-)) I tried

(making some data)

AX <-
data.frame(a=chartr(".",",",rnorm(5)),b=chartr(".",",",rnorm(5)),c=rnorm(5))


library(plyr)

adply(AX, 2, function(x){
if(!is.numeric(x[[1]]){
gsub(",", ".", x[[1]])
}else{
x[[1]]
}
})

and got the unwelcome error

Error: unexpected '{' in:
"adply(AX, 2, function(x){
if(!is.numeric(x[[1]]){"

Here is:

Re: changing "," to "." in data.frame

PIKAL Petr
Hi

missing ) after if statement.

adply(AX, 2, function(x){
if(!is.numeric(x[[1]])){
gsub(",", ".", x[[1]])
}else{
x[[1]]
}
})

However the data frame is transposed after the function which could be desired or not.

Cheers
Petr

Missing ) in if(!is.numeric(x[[1]]){

It should be

if(!is.numeric(x[[1]]) ){

Re: changing "," to "." in data.frame

PIKAL Petr
In reply to this post by tring
And as follow up,

fff<-function(x) gsub(",", ".", x)

BX <- apply(apply(AX, 2, fff), 2, as.numeric)

this seems to be easier.

Cheers
Petr

Along the lines of Petr's followup:

AXnew <- data.frame(lapply( AX, function(s) sub(",",".",s)))

Re: changing "," to "." in data.frame

David Carlson
In reply to this post by PIKAL Petr
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
