Re: [Rd] add Rvsnprintf to API ??

Could Rvsnprintf (in src/main/errors.c) be added to the R API

Here's my problem. I'm trying to write some code that is not
totally tied to R. Hence I want R style error messaging to
be isolated in a small module. I do not want #include R.h
and calls to error (Rf_error) in most of my code.
Hence I want to write a module with something like
- begin code snippet -
#include stdarg.h
#include stdio.h
#include R.h
#define BUFSIZE 1024
void die(const char *format, ...)
{
char buf[BUFSIZE];
va_list arg;
va_start(arg, format);
vsnprintf(buf, BUFSIZE, format, arg);
va_end(arg);
buf[BUFSIZE - 1] = '\0';
error(buf);
}
- end code snippet -
But that's not portable because vsnprintf isn't.
You've already made a big effort to work around nonportability of
vsnprintf, but don't make it available in the API. Why not?
If I could change vsnprintf to Rvsnprintf above, then I wouldn't
have to do some horrible autoconf song and dance that probably wouldn't
be completely portable anyway.
Or is there a better solution I haven't seen?
R guarantees to have *vsnprintf* available. Putting things in the API is
a one-way decision and ties our hands for ever. Rvsnprintf is not even
exported from errors.c: it is static and just a convenience wrapper.
About all a user package needs to do is
AC_CHECK_DECLS([vsnprintf])
and in your code snippet
#if defined(HAVE_DECL_VSNPRINTF) !HAVE_DECL_VSNPRINTF
extern int vsnprintf (char *str, size_t count, const char *fmt, va_list arg);
#endif
However, AFAIK all known R platforms do have vsnprintf these days: the
MinGW compiler used on Windows gained it within the last year.

Re: [Rd] Bug in axis labels (PR#7860)
This is fixed now, in R-patched and R-devel. Duncan Murdoch [EMAIL PROTECTED] wrote: Bob O'hara wrote: I'm a bit reluctant to call anything a bug: I know it's usually my incompetence instead. In this case, I can't see what else it is, although it may be a bug in Windows. The problem comes from trying to create a .png of a figure in Windows XP, with R2.1.0. On the screen it looks OK, but in the .png the text for the x label is smaller than for the y label. The problem seems to be created by using axes=F in plot(). Here's some code to demonstrate the problem: XX=1:5; YY=1:5 png(thing.png) par(mfrow=c(2,1)) plot(XX, YY, axes=F, xlab=X label, ylab=Y label) plot(XX, YY, xlab=X label, ylab=Y label) dev.off() I get a similar problem with bmp() and jpeg(), but not postscript() or pdf(). If I draw the figure in the window in R and then save it as a .png from the menu, the png looks fine. Everything works fine in R1.5.1 (I know, I know!) on Debian Linux, which is why I'm reporting this as a Windows problem. I see the problem in the first figure, and it's still there in a recent r-devel build. My test was also on Windows. Since png() uses the Windows graphics driver, it does look like an R bug in the Windows graphics driver, but I'd like to hear from someone on a different platform...

[Rd] PR$7706, png device plot on athlon 64 processor
A later bug report (#7860) had to do with inappropriate sizing of the first text drawn on a png() device, and I've now fixed the bug that caused that. Could you please check whether you still see your bug on today's build? It will be available on CRAN tomorrow (May 15), in http://cran.r-project.org/bin/windows/base/rpatched.html Thanks!

[Rd] Specifying dependency on a specific patched version
Is there a way to specify a package dependency in the Depends: field of the DESCRIPTION file for a specific patched version of a specific OS? For example, today's Windows patched release (2005-05-14) has the capability of changing the time zone within R on Windows via Sys.putenv(TZ=GMT) but prior patched versions do not have this. Is there some way of ensuring that the 2005-05-14 or later release is used if on Windows only? __ R-devel@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
