I suggest you issue the following command: ?pnorm
which will get you to a manual page that will give you information about the following commands: dnorm(x, mean=0, sd=1, log = FALSE) pnorm(q, mean=0, sd=1, lower.tail = TRUE, log.p = FALSE) qnorm(p, mean=0, sd=1, lower.tail = TRUE, log.p = FALSE) rnorm(n, mean=0, sd=1) John John David Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics University of Maryland School of Medicine Division of Gerontology Baltimore VA Medical Center 10 North Greene Street GRECC (BT/18/GR) Baltimore, MD 21201-1524 (Phone) 410-605-7119 (Fax) 410-605-7913 (Please call phone number above prior to faxing) >>> sandsky <[EMAIL PROTECTED]> 11/1/2008 5:39 PM >>> Is there anyone knowing a function or way for standard normal cumulative distribution?
