Code density functions

Dear Andy

Thanks for your reply.  I don't seem to find the file that you 
suggested. I tried:

file.show('C:/Program Files/R/rw1091/src/nmath/dnorm.c.')

NULL
Warning message:
file.show(): file C:/Program Files/R/rw1091/src/nmath/dnorm.c. does not 
exist

Then I looked at the directory and tried a file with similar name:

file.show('C:/Program Files/R/rw1091/src/include/Rmath.h')

But this file does not show the actual code used to calculate the 
densities, only the declarations of the procedures.

What am I doing wrong?

Thanks again!

Francisco Zagmutt :)

Dear <insert your name here>:

You need to look at the C-level source codes, in R-1.9.1/src/nmath/d*.c.

Hello

I would like to see the algorithm that R uses to generate
density functions
for several distributions (i.e. Normal,Weibull, etc).  I tried:

dnorm

function (x, mean = 0, sd = 1, log = FALSE)
.Internal(dnorm(x, mean, sd, log))
<environment: namespace:stats>

How can I see the code used for densities?

Thanks!
