Exuberant Ctags with R

Question

Is there any documented use of ctags with R? Would this be useful? Would it be difficult to implement?

Specifically, I\'ve just started using Vim. It would be cool to be

Answer 1

Universal-ctags has an R parser.

$ cat input.r
add <- function (x, y) {
    3 -> z
    return(x + y + z)
}
add (3, 4)
$ ./ctags --quiet --options=NONE -o - --kinds-R='*' --fields=+S input.r
add input.r /^add <- function (x, y) {$/;"  f   signature:(x, y)
x   input.r /^add <- function (x, y) {$/;"  z   function:add
y   input.r /^add <- function (x, y) {$/;"  z   function:add
z   input.r /^    3 -> z$/;"    v   function:add

In addition, the ctags implementation supports R6Class and S4Class.
