[R] Printing upon calling a function

You need to mention what you actually did to get proper advice. Your problem is at the source.
Simply put, the R interpreter does have somewhat different behavior when the program is directly typed in (or slightly indirectly as in R STUDIO) than when you ask it to open another file as a source, perhaps recursively.
If you read the manual page, "source()" has lots of options.
The default is to change some of the behavior with the assumption there is no user typing things in and waiting for responses. One of the options will change the behavior to make statements auto-print. Look to see if
gets what you want. Obviously the "..." above is replaced with your additional code. Of course, an explicit print statement works too. You may also want to look at the print.eval option.
What next? Will you now tell us you forgot that you used the sink(file="hide.txt") function in the code and wonder why it does not print to your terminal?

No. I wrote the function so I am sure no "invisible" command was used.
Strangely enough, compiling the function isto part of a package, results were NOT printed. Yes if I call the function during run, by preceding the call with a line that attach the source code:
it did print. I do not understand.
