Dear help I have been attenpting to compile R0.49 on both of these unix machines and have had no compilation errors but core dumps at run time. The HP UX box start out by putting up a graphics window and then crashing with the following error message before giving the prompt R : Copyright 1997, Robert Gentleman and Ross Ihaka Version 0.49 Beta (April 23, 1997) R is free software and

I came across a quite interesting post from Ross Ihaka, thought would be good to share it and get the opinion of folks around here.

Full_Name: Skylab Gupta Version: R version 2.5.1 (2007-06-27) OS: Windows XP Submission from: (NULL) (216.82.144.137) Hello, I have been playing around with the statistical distributions in R. I think the computations for the cumulative distribution function of the students t distribution in R are not very accurate. For instance, the cdf of a students t distribution with 13 degrees of freedom

Hi Ross - I believe I was wrong in thinking that passing via the ... list to stripchart() was ever allowed. Here are patches: Add ... to the argument list Add, at the beginning of the function: pars <- list(...) There are two calls to axis(). Modify these to: axis(1, at = at, labels = names(groups), las=pars$las) axis(2, at = at, labels = names(groups), las=pars$las) Also

We have two lectureship positions advertised at the moment. One (or both) of these is intended for a specialist in statistical computation. The salary doesn't look great by international standards but there are compensations: housing is cheap, the air is clean, and the worlds problems are far away. We also have a track record of getting tenure for computing people.

On 23/02/05 I suggested that given R had included TOMS 708 to correct for t= he=20 poor performance of pbeta, TOMS 654 should be included to fix all the pgamm= a=20 problems. I was slightly surprised to find Morten's code had been included= =20 instead 2 days later. I noticed but did not worry that the reference to me = had=20 been removed.=20 The derivation of the asymptotic expansion for

Is it conceivable that Julia could be ported to use R syntax in a way that would allow the vastly larger numbers of R programmers to seamlessly switch? Or equivalently, could an iteration of R itself do this?

Hello, I have been playing around with the statistical distributions in R, and overall I think the accuracy is very good. However, it seems that for the Student's t distribution, the CDF loses accuracy when evaluated at values close to zero. For instance, I did the following in R ---------------------------------- df<-seq(1,100,by=1)
