[R] How to replace all commas with semicolon in a string

Dear list,

Say I have a data frame

test <- data.frame(C1=c('a,b,c,d'),C2=c('g,h,f'))

I want to replace the commas with semicolons

sub(',',';',test$C1) -> test$C1 will only replace the first comma of a string.

How do I replace them all in one run? Thanks.
