using Rmath standalone
...the Rsource and compiled the library as recommened (compiled on windows 98 using the cygwin environment). But whenever i try to use functions from the library i get similar error messages -
eg. using the function dnorm(double, double...... etc ) i get the message : "undefined reference to dnorm4".
dnorm4 is called by dnorm to implement the function, but for some reason the function isn't being implemented. Can anyone suggest what might be a solution to this? I have tried including all the relevant directories in my compiler path for both inlcude and library files. I don't kn...

What should dnorm(0, 0, -Inf) return?
Hi,
Apropos of a recent Inf question, I've previously wondered if dnorm "does the right thing" with
dnorm(0, 0, -Inf)
which gives zero. Should that be zero or NaN (or NA)?
The help says "'sd < 0' is an error and returns 'NaN'" and since -Inf < 0 is TRUE, then... is this a bug?
Thank you,

What should dnorm(0, 0, -Inf) return?
Good question, I cannot speak for R's developers but I would like to
provide some information on the problem. Here are the first few lines of
the dnorm function located at src\nmath\dnorm.c:
```
double dnorm4(double x, double mu, double sigma, int give_log)
{
#ifdef IEEE_754
if (ISNAN(x) || ISNAN(mu) || ISNAN(sigma))
return x + mu + sigma;
#endif
if(!R_FINITE(sigma)) return R_D__0;
if(!R_FINITE(x) && mu == x) return ML_NAN;/* x-mu is NaN */
if (sigma <= 0) {
if (sigma <...

Minor inconsistencies in tools:::funAPI()
Hi Ivan
Can you please clarify what input files should be used with your
proposed function? I tried a few files in r-svn/src/include and one of
them gave me an error.
