R help - Nov 2009 - getting the name of a single object in R for debugging output

I often use a debug flag (set to TRUE) to turn on various debugging print
statements in my R scripts.  I was thinking I should create a function
debugPrint(object,debugFlag),
to print out the object name and contents if the debugFlag is set to TRUE.  Then
I wouldn't have to make my script ugly(..er) than it already is by adding IF
statements all over the place.  I've seen how ls() dumps object names, but
how do I get access to the character representation of the name of an object.

E.g.

myVar<- 10

print(myVar) produces "10"

I'd like to print out something like " myVar : 10"

I'd appreciate any suggestions.

Regards,

Andrew

Try this:

debugPrint <- function(x, ...){
	print(sprintf("%s: %d", deparse(substitute(x)), x), ...)
}
