Dear R-Helpers, I suspect I'm about to ask a FAQ, but I haven't been able to find an answer in the FAQ, AItR or an R Site Search. When I look at the methods of summary (below) it says, "Non-visible functions are asterisked". I looked at the help file for summary.princomp, which did not comment on it being non-visible. I ran its help file example, which printed visible output. I did not notice ho...

...arguments are passed to persp() _and_ lines() and this gives warnings. QUESTION: What is best practice to handle this sort of problem? Should I ignore the warnings() that this approach gives? I can suppress them with options(warn= -Inf), but is this a good idea? I've read section 10.4 of AITR. (the odd argument jj.colour is there because persp() needs to be called with col=NA). -- Robin Hankin Uncertainty Analyst Southampton Oceanography Centre SO14 3ZH tel +44(0)23-8059-7743 initialDOTsurname at soc.soton.ac.uk (edit in obvious way; spam precaution)

...ading two packages at startup, which is working fine with this code: local({ myOriginal <- getOption("defaultPackages") myAutoLoads <- c("Hmisc","ggplot2") myBoth <- c(myOriginal,myAutoLoads) options(defaultPackages = myBoth) }) But when reading AITR, I noticed it has a .Rprofile example that looks much simpler. It just loads the one additional package without checking the defaultPackages. Is this just as good? Does it even need to be in the .First function definition, or could it simply be a command by itself in .Rprofile? .First <- functi...

...nput & output to myresults.txt with this approach: $script myresults.txt $R > ...r commands... >q() $exit I can also use the Linux tee command to do essentially the same thing. Both of those approaches do what I want, but I assume there is a way to do it within R. I've been through AITR Appendix B and the FAQ looking for either a startup option or an R function to do this but I don't see either. What am I missing?
