For what it's worth, with

Yes, C does use call by value, always. However, data arrays
are almost always passed via pointers to malloc'ed space,
so, effectively, data arrays are passed by reference.
(One can put a 'const type*' in the prototype of a function to declare
that the data pointed to will not not be changed, but i

Hello,
I am trying to call the BLAS Level1 function zdotc from R via
a .C call like this:
#include "R.h"
#include "R_ext/BLAS.h"
void testzdotc() {
Rcomplex zx[3], zy[3], ret_val;
zx[0].r = 1.0; zx[0].i = 0.0;
zx[1].r = 2.0; zx[0].i = 0.0;
zx[2].r = 3.0; zx[0].i = 0.0;
zy[0

I haven't used Julia yet, but from my quick reading
of the docs it looks like arguments to functions are
passed by reference and not by value, so functions
can change their arguments. My recollection from when
I first started using S (in the course of a job helping
profs and grad students do stati
Hi,
if you use the plot.TukeyHSD() function with a main argument, that one
is printed over the default title 'X% family-wise confidence level'.
Try for example:
Model <- aov(count~spray,data=InsectSprays)
plot(TukeyHSD(Model),main='H',las=2)
This doesn't happen with an xlab or ylab argument,
10 matches
