How to substitute dashes with dots in every element of character vector in R?

Question

Is there an easy way to substitute dashes with dots in every element of character vector in R?

input
c("T-A-B", "C-L1")
output
c("T.A.B", "C.L1")

Was looking for help in stringi package but couldn't find answer. There is stri_substitute function but I don't know how to use this.

usually use `gsub` but in this case `make.names(c("T-A-B", "C-L1"))` — user20650, Feb 04 '15 at 22:04
I like the `make.names` usage here. Very refreshing. If you want a `stringi` solution, try `stri_replace_all_fixed(c("T-A-B", "C-L1"), "-", ".")` — David Arenburg, Feb 04 '15 at 22:15

Base R like this (gsub vectorized thanks to @docendo):

> gsub("-",".",c("T-A-B", "C-L1"))
[1] "T.A.B" "C.L1"

Or with stringr:

> library(stringr)
> str_replace_all( c("T-A-B", "C-L1"),"-",".")
[1] "T.A.B" "C.L1"
