a R_PV problem
Dear all,
When using gdb to debug my C code, I use R_PV to show the content of
SEXP variables:
SEXP sexp; // it is a data.frame
SEXP colNames = getAttrib(sexp, R_NameSymbol);
A strange thing is that after halting the program:
(gdb) p R_PV(colNames)
does not show the content of colNames. I am positive my code is right

Questions about piecewise spline fitting
Hi All,
I want to fit a piecewise spline of degree 1, i.e. a spline consisting of a
straight line over each piece. I downloaded the R package pspline, then I
have following questions:
1. in the program, the degree of the spline is specified by 2*norder-1. Why
do they adopt such scheme that we can only fit a spline with odd degree?
2. norder cannot be set to 1. Is there any specific reason
