I am missing (or not aware) of a feature in ESS to run some R code on selected text. When editing a script, like

df1 <- data.frame(a=1:100,b=rnorm(100))

I often want to see head(df1) in my terminal. I'd like to be able to move the cursor to df1 and run an elisp function that sends head(df1) to the R terminal. Can you direct me to how to do that, please? If I can define a few R-functions in Elisp functions and assign them to shortcuts, it would often ease my workflow.

Here's a quick and dirty approach. Depending on what you want there's lots of room for improvement.

(defun head-at-point ()
 (interactive)
 (let ((target (thing-at-point 'symbol)))
 (ess-send-string (ess-get-process ess-local-process-name)
 (concat "head(" target ")n"))))
