How to turn one symbol into another

Im trying to find a way to substitute out the "|" symbol in this dataset for the "/" symbol
df<-c(2|4,5|6,3|4,4|7,5|8)
So that way the final would look like
df<-c(2/4,5/6,3/4,4/7,5/8)

Any help would be great thankyou

>Solution :

If it is a single string (or a vector of elements) use chartr from base R

chartr("|", "/", df)
[1] "2/4,5/6,3/4,4/7,5/8"
df2$col1 <- chartr("|", "/", df2$col1)
> df2
  col1
1  2/4
2  5/6
3  3/4
4  4/7
5  5/8

data

df <- "2|4,5|6,3|4,4|7,5|8"
df2 <- data.frame(col1 = c("2|4", "5|6", "3|4", "4|7", "5|8"))
