Hello,
It means you should update your version of R. paste0 was introduced with
R 2.15.0 as is the shorter equivalent of
paste(..., sep = "")
I'm sending you a small correction just in case some of the elements in
A only have 1 element.
fun <- function(X){
xname <- deparse(substitute(X))
s <- strsplit(X, "/")
n <- max(sapply(s, length))
tmp <- numeric(n)
f <- function(x){
x <- as.numeric(x)
m <- length(x)
if(m > 1){
tmp[n] <- x[m]
tmp[seq_len(m - 1)] <- x[seq_len(m - 1)]
}else tmp[1] <- x
tmp
}
res <- do.call(rbind, lapply(s, f))
colnames(res) <- paste(xname, seq_along(s), sep = "")
data.frame(res)
}

Hi Rui,
I am getting some error message in the code you sent. It says "Error in fun(A) : could
not find function "paste0"
I am a new in R so could not fix it. Can you help me fix that ?
Thanks

Subject: Re: [R] splits with 0s in middle columns
Hello,
Try the following.
A <- c(
"10/20/30",
"40/20",
"60/10/10/5",
"80/10")
fun <- function(X){
xname <- deparse(substitute(X))
s <- strsplit(X, "/")
n <- max(sapply(s, length))
tmp <- numeric(n)
f <- function(x){
x <- as.numeric(x)
m <- length(x)
tmp[n] <- x[m]
tmp[seq_len(m - 1)] <- x[seq_len(m - 1)]
tmp
}
res <- do.call(rbind, lapply(s, f))
colnames(res) <- paste0(xname, 1:ncol(res))
data.frame(res)
}
fun(A)
Hope this helps,

Hi,
A column of my df looks like
A
10/20/30
40/20
60/10/10/5
80/10
I want to split it such that the last column has the last composition and if
there are not enough the middle columns get the 0s. That way my df would look
like
A1 A2 A3 A4
10 20 0 30
40 0 0 20
60 10 10 5
80 0 0 10
How can I do that ??
