Colleagues,

I have encountered the following problem using R2.7.0 in Windows  
(Vista).

I want to delete a series of functions before I close an R session.  I  
execute the following commands from a script:

FunctionsToDelete	<- c("function1", "function2", "function3")

for (EachFunction in FunctionsToDelete)
	{
	if (exists(EachFunction))
		{
		remove(EachFunction)
		 } else invisible()
	}

This results in a series of warning messages (one message per entry in  
FunctionsToDelete):
	Warning in remove(EachFunction)  :  variable "EachFunction" was not  
found

I tried one variant, changing:
	remove(EachFunction)
to
	remove(list=EachFunction)

Warnings are now issued in the form:
	Warning in remove(list=EachFunction) : variable"function1" was not  
found
	Warning in remove(list=EachFunction) : variable"function2" was not  
found
	
Any thoughts as to the problem?

Dennis
