I don't believe your message actually came from R's XERBLA. Note that the=
=20
name is not quoted and that the name of the routine is not 6 characters=20
long.
Actually, it did.
You seem to be agreeing that it did not (which is the truth).
I didn't quote the message exactly (as I said).
You didn't say, and the posting guide does ask you to do so exactly.
Now, I took the liberty to make my own suggested change in
R-devel_2005-08-28 and rebuilt, and you may guess what error message I
got.;)
Error in coxreg.fit(X, Y, rs, strats, offset, init, max.survs, method, :
The BLAS/LAPACK routine 'DSYR ' gave error code -7
BTW, the original BLAS xerbla (from the netlib page you referred to)
gives the message:
WRITE( *, FMT = 9999 )SRNAME, INFO
9999 FORMAT( ' ** On entry to ', A6, ' parameter number ', I2, ' had ',
$ 'an illegal value' )
which I think is even better than my original suggestion.
(Why was it changed?)
Probably because R is not a Fortran program and so needs to make clear
what these refer to, and because LAPACK does have other error values that
invalid parameter values.

Here is a genuine example from R:
Error in La.svd(x, nu, nv) : LAPACK routine 'DGEBRD' gave error code -10
There is no R 2.2.0, BTW. If referring to R-devel, please do so with an=20
SVN revision.

Some BLAS routines call xerbla for error messages, which results in a mes=
sage
like
"LAPACK routine DGER gave error code -9".
Suggested solution: In
void F77_NAME(xerbla)(char *srname, int *info)
{
/* srname is not null-terminated. It should be 6 characters. */
char buf[7];
strncpy(buf, srname, 6);
buf[6] =3D '\0';
error(_("LAPACK routine '%6s' gave error code %d"), buf, -(*info));
}
change 'LAPACK' to 'The' (or 'The BLAS/LAPACK').
