similar to: power.t.test needs to check delta==NULL before abs(delta) (PR#3140)

Something like the following should be done for power.t.test to make sure that it doesn't try to evaluate abs(NULL), which results in an error. --- rossini.power.t.test.R 2003-05-30 07:24:49.000000000 -0700 +++ rossini.power.t.test.R.~1~ 2003-05-30 08:47:09.000000000 -0700 @@ -10,7 +10,7 @@ alternative <- match.arg(alternative) tsample <- switch(type, one.sample = 1,

Greetings, I've tried to update the power.t.test function to allow for different sample sizes and sample variances in the case of a two-sample t test. I'd gladly update the corresponding help page if the code is to replace the current power.t.test function. The modified power.t.test code is included below. The changes are as follows: - Added three new arguments to the function *

One thing that has driven me batty to no end is the fact that ESS doesn't handle R's "exit" well. Any thoughts as to the default? I'm thinking of something like: current: do what currently is done C-u Y C-c C-q : quit and save workspace C-u N C-c C-q : quit and don't save workspace. Comments? best, -tony -- A.J. Rossini Rsrch.

There's a bit of a symmetry issue, which may or may not be important (led to 15 seconds of confusion until I got my bearings straight): row.names, rownames; colnames, no col.names? I _NOW_ realize the difference between row.names and rownames, but is there any reason not to have col.names for re-naming columns in a data.frame? (if there is, I don't particular need to know it, but it

Is there a simple way to determine at run-time the directory with HTML version of help pages?

It's cool, it's exciting, and much thanks to Duncan. He announced RJava yesterday (or this morning?) on the R-devel list, and it's really worth it. http://www.omegahat.org/RSJava for more details. But it does mean that we can run Orca code directly within R, (without Thomas' socket connections) (and also means that we really need a "stop" button, since killing

Another example: Jerry Friedman's MART is available in R from Salford for the same price as the stand-alone TreeNet, even though they don't advertise it on their web site.

Duncan - (but sent to R-devel, for any other thoughts?) How do you envision RSPerl being used? Without having seen the details, I can think of playing with strings; is there a preferred incantation for stringification of R objects (serialization)? (actually, the main problem I'm having is that I know how I want to code something like: Robject <-

Hi to all who suffer from rterm not shutting down in xemacs/ESS on windows NT or 2000. Also hi to those who could eventually help. Here is some more information which could help and some ENCOURAGEMENT to contribute to a solution. 1. It may be an xemacs problem but it is more likely an interaction between rterm/comint/and xemacs. In fact, the problem started occurring around version R 1.6.0. I

I observed the same behavior as Edward this morning with R-1.2.2 on Red Hat Linux 7.0. There appears to be a problem with the library in netpbm-9.5-5, even after hunting down the missing shhopt.h that pbmplus.h is looking for. I worked around the problem by compiling e1071 without pbm support (moved pbm.c to pbm.c.bak). Matt Matthew R. Nelson, Ph.D. Director, Information Systems Esperion
