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.
