When executing the command:
print(cat(paste("Input criteria does not meet specifications. Check
input against the following requirements:
a >= 0
b <= 0
c >= 0 ", sep=""), ""))
I get:
Input criteria does not meet specifications. Check input against the
following requirements:
a >= 0
b <= 0
c >= 0 NULL
(with that extra NULL at the end).
If I omit the 'cat' command, the NULL goes away, but I no longer get the
next-line formatting that I want.
I think I'm missing something about one of these functions returning a NULL
value, but I can't seem to get the exact result I want (no NULL value, and
keep the next-line formatting.)
Any ideas or suggestions are much appreciated.
Thanks!
