Have a class for which I would like to provide a "colnames<-.myclass"
function so that
colnames(myintsance) <- c("a","b","c")
can be called.

Dear devels,
I need to create a (short) vector in C, which contains potentially very
large numbers, exponentially to the powers of 2.
This is my test example:
lgth = 35;
int power[lgth];
power[lgth - 1] = 1;
for (j = 1; j < lgth; j++) {
power[lgth - j - 1] = 2*power[lgth - j];
}
Everything
Hi Witold,
you should first of all redefine colnames to use UseMethod.
Then you have to write a colnames.default that uses base::colnames
(so that it does not interfere with existing code and other functions)
and the you can define the method for your class.
I would suggest, though, to use attribu

This isn't an R question, except in so far that R mandates the usual
convention of C being 32-bit. However

Dear Prof. Ripley,
Once again, thank you for your replies.
I must confess not being a genuine C programmer, having learned how to use
C only in connection to R (and the macros provided are almost a separate
language to learn).
I'll try to read more about the types you've indicated, and will keep

I am simply using Rprintf():
long long int power[lgth];
power[lgth - 1] = 1;
Rprintf("power: %d",

`colnames<-` is not generic as Luca noted.
But `dimnames<-` is.
If you write a suitable `dimnames<-.myi
Hi,
read.dcf() can modify the locale variable LC_CTYPE, and here is a
minimal example:

[1] "en_US.UTF-8"

a
1 b
> Sys.getlocale('LC_CTYPE')
[1] "C"
After diagnosing the problem, it seems the on.exit() call in
read.dcf()

Oh my goodness, this was a printing issue...!
