rounding
Hi,
Round(0.55,1)=0.5
Round(2.55,1)=2.6
Can this be right?
Thanks,

Still having trouble with slow opening of printer properties
List,
I asked a while back about problems with very slow openings of printer
properties windows. This afternoon our main internet link was upgraded
to 6Mb (symmetric) and so I thought I might see some improvements in
response.
But no change. I really don't think it's the pipe that's at fault,
there's something wrong with my samba configuration. When I open the

logical operations with lists
Sorry, maybe it's easy but I haven't found anything useful:
how can I obtain a list C that contains all the members in the list B that are not in list A? This are lists of nanes, not numbers!
Thank you

question about dll crashing R
I have ported some R code to C to make it faster.
I can perform .Call("foobar",....) once and it
works fine. Absolutely correct answer.
If I put a loop inside foobar and run the main code
routine more than 100 times, it crashes R.
Or if I call .Call("foobar"....) seperately more than
two tims it crashes R.
For the most part I am doing matirx multiplies using

When calling external C-function repeatedly I get different results; can't figure out why..
Dear all,
I need to calculate tr(xyxy) fast for matrices x and y. Inspired by the R-source code, I've created the following functions (I am *new* to writing external C-functions, so feel free to laugh at my code - or, perhaps, suggest changes):
#include <Rinternals.h>
#include <R_ext/Applic.h> /* for dgemm */
static void matprod(double *x, int nrx, int ncx,
double *y, int

Not an expert in programming either, but to me it seems like you've forgotten to initialize the variable "tr". It just picks up garbage from allocated memory previously initialized by other processes.

Using matprod from array.c
Hi,
I was wondering if I could use the matprod function from array.c in my own C routine. I tried the following as a test
/* my_matprod.c */
# include <Rinternals.h> /* for REAL, SEXP etc */
# include <R_ext/Applic.h> /* array.c says need for dgemm */
/* following copied from array.c */
static void matprod(double *x, int nrx, int ncx,
double *y, int nry, int ncy, double *z)

i don't know the status of nci, but suif/suif2 development and
publication is very active. it's will be great if there are tools to
transform llvm ir and suif ir to each other. acutally, i didn't use
suif but llvm just because suif cannot be compiled by visual
studio.net (but visual studio 6).

Speeding up matrix multiplies
I've looked at the code for matrix multiplies in R, and found that it
can speeded up quite a bit, for multiplies that are really vector dot
products, and for other multiplies in which the result matrix is small.
Here's my test program:
u <- seq(0,1,length=1000)
v <- seq(0,2,length=1000)
A2 <- matrix(2.1,2,1000)
A5 <- matrix(2.1,5,1000)
B3 <- matrix(3.2,1000,3)
A4 <-

Internal state indicating if a data object has NAs/no NAs/not sure (Was: Re: Speeding up matrix multiplies)
Hi, I'm just following your messages the overhead that the code for
dealing with possible NA/NaN values brings. When I was setting up
part of the matrixStats package, I've also though about this. I was
thinking of having an additional logical argument 'hasNA'/'has.na'
where you as a user can specify whether there is NA/NaN:s or not,
allowing the code to avoid it or not.

[EXTERNAL] Re: NOTE: multiple local function definitions for ?fun? with different formal arguments
Because functions get called and therefore, the calling sequence matters. It?s just protecting you from yourself, but as someone pointed out, there?s a way to silence such notes.

how can I plot bar plots with all the bars (negative and positive) in the same direction????
Dear r-help mailing list,
this seems stupid, but I actually don't find the solution:
if I have a vector of numbers x of length n, ranging, say, from -3 to 4, if I do
barplot (x)
all the values below 0 go downwards, and all the positive values go upward. How can I make them all begin from the minimum pointing upwards?
Thanks!

[EXTERNAL] Re: NOTE: multiple local function definitions for ?fun? with different formal arguments
Here's a dummy example that I think illustrates the problem:
toto <- function() {
if (runif(1) < 0.5)
function(a) a
else
function(a,b) a+b
}
> fcn <- toto()
> fcn(1,2)
[1] 3
> fcn <- toto()
> fcn(1,2)
[1] 3
> fcn <- toto()
> fcn(1,2)
Error in fcn(1, 2) : unused argument (2)
How can you use the returned function, if you get different arguments?

how to create automatically names for vectors in a loop?
Hi,
I want to generate a number of vectors and store them with different names, like this:
x=1
while (x<100)
{
vector#x# = rnorm(100)
x=x+1
}
where each vector has, at its hand, instead of #x# a number which goes from 1 to 99.
How can I do this?
Thanks

how to call function in ../src/main
Hi, This is Kotien Wu from NIH/NCI.
We want to use R function for our web:
http://cgap.nci.nih.gov
It works for functions in R/R-1.9.1/src/nmath/standalone very well.
We have function GetPvalueForT.c which has
#define MATHLIB_STANDALONE 1
#include <Rmath.h>
double GetPvalueForT ( double t, double deg ) {
return 2 * pt(t, deg, 0, 0);
}
We create GetPvalueForT.i, which has
