[R] Tracking what R actually executes

This question is probably conceptual rather than technical and I have not thought out all of the issues yet.  Let’s say I have an extensive list of functions and some lines of code that call the functions.  I would like to have a record of all the commands that were actually executed.  I realize that this could be voluminous but it might be necessary.
For example, the code and function might be:

###############
INPUT:
COUNTER	<- function(N)
	for (i in 1:N)	cat(“count”, i, “\n”)
COUNTER(10)

###############
OUTPUT:
cat(“count”, 1, “\n”)
cat(“count”, 2, “\n”)
cat(“count”, 3, “\n”)
cat(“count”, 4, “\n”)
cat(“count”, 5, “\n”)
cat(“count”, 6, “\n”)
cat(“count”, 7, “\n”)
cat(“count”, 8, “\n”)
cat(“count”, 9, “\n”)
cat(“count”, 10, “\n”)

If I have formulated the question poorly, please do you best to understand the intent.
