Problem w/ axis and distortion in a plotting function
I have a function for plotting soil texture that I am having a problem with.
The function is:

y.con <- y*sin(1/3*pi)
data.frame(x=x.con, y=y.con)

I can't make .C(...) web-page example.
Hi everyone!
I'm trying to lear how to call external C code in R but even the R help
web-page example is drive me crazy.
I copy-paste the example at:
http://stat.ethz.ch/R-manual/R-patched/doc/manual/R-exts.html#Interface%20functions%20.C%20and%20.Fortran
here is the example:

{
int i, j, nab = *na + *nb - 1;
for(i = 0; i < nab; i++)
ab[i] = 0.0;
for(i = 0; i < *na; i++)
for(j = 0; j < *nb; j++)
ab[i + j] += a[i] * b[j];
}

and then................
