something like "sprintf" in C?
so I can do:
print(sprintf("the correct result is %3.4f\n", myresult));
-------
Also, I am desperately looking for a "clear console screen" function
in
R...
thanks a lot!

It actually works in R, although you would probably prefer cat() instead of print(). -thomas> > ------- > > Also, I am desperately looking for a "clear console screen" function in > R... > > thanks a lot! > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html >Thomas Lumley Assoc.

You really need to learn how to do some searching, as you seem to
be constantly asking questions you can answer yourself
help.search("sprintf")

Great! It worked! Thank you so much! Now since it worked greatly, how can I put this function into my own library or package, so later on I can call this function from my other scripts? Thanks a lot!

People here provide their time for free and it is not much to expect posters to try to help themselves out first - especially as the developers have gone to such great lengths to produce quality documentation that explains all of this.

It is way too complicated.If an amateur like me can do it, I'm quite sure a CS degree is not needed. How many packages available on CRAN do you think were created by those with CS degrees? How many in R Core do you think have CS degrees?> There should be simpler ways.There are, and this question has been asked and answered many times over on this very list. Please do learn to search the archive, as the posting guide asks you to.
