this is rather simple since you can communicate with R via AppleScript.

Create a new tmCommand with:
----------------------------------------
#!/usr/bin/env bash
[[ -f "${TM_SUPPORT_PATH}/lib/bash_init.sh" ]] && . "${TM_SUPPORT_PATH}/lib/bash_init.sh"


Rcmd="length($TM_SELECTED_TEXT)"

osascript <<-APPLESCRIPT
tell application "System Events"
    tell application "R" to cmd "${Rcmd//\"/\"}" 
end tell
APPLESCRIPT
----------------------------------------

Input: Selection; format: Text
Output: Discard
Key Equivalent: "whatever you like"

The 4th line of code is the interesting part:

- $TM_SELECTED_TEXT holds the content of the current selection
- Rcmd is the variable whose content will send to R.app - thus in that example it will send "length({content of selection})"  


Hope it helps.
Cheers,
Hans
