Box muller algorithm r

WebThe R source code for this is here: myrnorm.r. Again, because this procedure can be entirely vectorised, it will be very fast and efficient in R, and so there will be little to be gained from re-coding in C. Implementation in C In order to get a bit more of a feel for C, we'll see how to write some code to generate Normal random quantities.
