Re: Convert ASCII string to Hex in R (vice versa)
Difficult to understand what you want: could be
x = 32
(b = sprintf("%x",x) )
Also check hexmode/as.hexmode

Dear Colleagues,
I have run the following two models, where category has 3 levels and comp
has 8 levels:
mod1 <- lmer(x~category+comp+(1|id),data=impchiefsrm)
mod2 <- lmer(x~category+comp+category*comp+(1|id),data=impchiefsrm)
followed by:
anova(mod1,mod2)
The anova shows that the interaction t
Dear Gabor,
Thank you (again) for this second suggestion, which does exactly what I
want. At the risk of appearing ungrateful, and although the judgment is
admittedly subjective, I don't find it simpler than mysort().
For curiosity, I tried some timings of the two functions for the sample
problem
Another possibility is to use strapply in gsubfn giving a solution
that is non-recursive and shorter:
library(gsubfn)
mysort2 <- function(s) {
L <- strapply(s, "([0-9]+)|([^0-9]+)",
~ if (nchar(x)) sprintf("%9d", as.numeric(x)) else y)
L2 <- t(do.call(cbind, lapply
Dear Gabor,
Thanks for this -- I was unaware of mixedsort(). As you point out,
however, mixedsort() doesn't cover all of the cases in which I'm
interested and which are handled by mysort().
Regards,
John

Dear r-helpers,
I'm looking for a way of sorting variable names in a "natural" order, when
the names are composed of digits and other characters. I know that this is a
vague idea, and that sorting character strings is a complex topic, but
perhaps a couple of examples will clarify what I mean:

Hello,
Dear all,
For example I want to process set of files.
Typically Perl's idiom would be:
__BEGIN__
@files = glob("/mydir/*.txt");
foreach my $file (@files) {
# process the file
}
__END__
What's the R's way to do that?
