search for: erfc

I am converting some matlab code into R that use inverse of the complementary error function, erfcinv and did not find an equivalent in R, is there such a function in some contributed modules? Thanks.

In the latest R 2.8 alpha for Win32, if either of the commands are typed: > help("erfc") .. or .. > ?erfc the result is: No documentation for 'erfc' in specified packages and libraries: you could try '??erfc' This should be: 'help.search("erfc")', as shown in R 2.7.2 Apologies if this has already been submitted/fixed. -Mike --please do not...

...y be wrong, (and often am), but in trying to determine how to calculate the erf function, the documentation for 'pnorm' states: ## if you want the so-called 'error function' erf <- function(x) 2 * pnorm(x * sqrt(2)) - 1 ## and the so-called 'complementary error function' erfc <- function(x) 2 * pnorm(x * sqrt(2), lower=FALSE) Should, instead, it read: ## if you want the so-called 'error function' erf <- function(x) 2 * pnorm(x / sqrt(2)) - 1 ## and the so-called 'complementary error function' erfc <- function(x) 2 * pnorm(x / sqrt(2), lower=FAL...

Dear all, The package NORMT3 which computes the erf, erfc functions as well as the exact values of the convolution of a Gaussian with a Student's t 3 distribution has been enhanced with the addition of a function to compute Faddeeva's function. Thanks to Krishna Myneni for this addition. Guy Nason [[alternative HTML version deleted]] __...
