dyn.load for c code
I am learning how to load C code into R-1.8.0 on Windows 98. To this end I wrote
a small c program, downloaded the tools, perl, and mingw on the "building
R for windows" page, and proceeded to create libR.a & libRblas.a as explained
in the readme.packages. I started with a simple c program called mysum.c that can
be found on:

Adding two or more columns of a data frame for each row when NAs are present.
I am fairly new to R and would like help with the problem below. I am
trying to sum and count several rows in the data frame yy below. All works
well as in example 1. When I try to add the columns, with an NA in Q21, I
get as NA as mySum. I would like NA to be treated as O, or igored.
I wrote a function to try to count an NA element as 0, Example 3 function.
It works with a few warnings,

How to call Java main method using rJava package?
Hi,
I am trying to integrate my Java program with R using rJava package. I want
to execute the whole Java program from R. The main() method in my Java code
calls all the other defined methods. So, I guess I have to call the main()
method in .jcall.
An example Java code:
*class A {
public static int mySum(int x, int y) {
return x+y;
}

optim seems to be finding a local minimum
Hello!
I am trying to create an R optimization routine for a task that's
currently being done using Excel (lots of tables, formulas, and
Solver).
However, otpim seems to be finding a local minimum.
Example data, functions, and comparison with the solution found in
Excel are below.
I am not experienced in optimizations so thanks a lot for your advice!

Function call within a function.
I am trying to call a funtion within another function
and I clearly am misunderstanding what I should do.
Below is a simple example.
I know lstfun works on its own but I cannot seem to
figure out how to get it to work within ukn. Basically
I need to create the variable "nts". I have probably
missed something simple in the Intro or FAQ.
Any help would be much appreciated.

Using R function in Excel
Does anyone know a way that an function written in R can be called within a cell of an Excel spreadsheet. I would like to use the R function much as I use the native Excel functions, e.g. instead of using the excel function sum, =sum(A2,A6), I would like to use the function mysum written in R, e.g. =mysum(A2,A6).
Thanks,
John

Incorrect comment about ISNA(x) in Arith.h (PR#13826)
R-2.9.0/include/R_ext/Arith.h has:
int R_IsNA(double); /* True for R's NA only */
int R_IsNaN(double); /* True for special NaN, *not* for NA */
int R_finite(double); /* True if none of NA, NaN, +/-Inf */
#define ISNA(x) R_IsNA(x)
/* True for *both* NA and NaN.
The first and last lines are contradictory - if R_IsNA is true only
for NA, not NaN, then ISNA should be the same.

optim and optimize are not finding the right parameter
Dear all,
I have a function that predicts DV based on one predictor pred:
pred<-c(0,3000000,7800000,15600000,23400000,131200000)
DV<-c(0,500,1000,1400,1700,1900)
## I define Function 1 that computes the predicted value based on pred
values and parameters a and b:
calc_DV_pred <- function(a,b) {
DV_pred <- rep(0,(length(pred)))
for(i in 1:length(DV_pred)){
DV_pred[i] <- a *

How to force aggregate to exclude NA ?
The aggregate function does "almost" all that I need to summarize a datasets, except that I can't specify exclusion of NAs without a little bit of hassle.

[LLVMdev] "fork" and "sync" for LLVM thread support - any comments?
Dear all,
Recently I've wanted to add support for threads to LLVM (motivated by
OpenMP, more or less), but before jumping in and implementing anything,
I thought it might be a good idea to describe what I have in mind and
ask for comments. Hence this email - if anyone has any comments, I'd be
very glad to hear them.
WHAT I'M PROPOSING:

render html partial from atom builder
So I have an action that results in atom:
def index
...
respond_to do |format|
...
format.atom { render :layout => false}
end
end
Then I have a builder template to render the atom, called
index.atom.builder.
Inside this builder template, I''d like to render one of my existing html
partials, to put in the atom:content element, perfectly normal atom
thing to do.

Linking Rblas
Dear all,
when making a DLL via Rcmd SHLIB is there a way to link against a
library such as Rblas (I am on a Windows platform) on a case to case
basis?
I played a bit around with some self-written C-code which should call
the function 'dasum' defined in Blas.h.
I encountered the following problem:
u:\codeplay>Rcmd SHLIB mysumming.c

Dear Prof. Ripley,
thank you very much. It works now absolutely fine using a "Makevars"

Thanks again,

function corresponding to map of perl
Is there a function in R that corresponds to the
function ``map'' of perl?
It could be called like:
vector.a <- map( vector.b, FUN, args.for.FUN )
It should execute for each element ele.b of vector.b:
FUN( vector.b, args.for.FUN)
It should return a vector (or data.frame) of the results
of the calls of FUN.
It nearly works using:
apply( data.frame( vector.b ), 1, FUN,

A coding question
Dear List:
I have the follow code:
y <- replicate(10,replicate(8,sum(rnorm(rpois(1,5)))))
Now I need to apply the following condition to _every_ randomly generated
Normal number in the code above:
x - max(0,x-15) + max(0,x-90), where x represents the individual Normal
numbers.
In other words, the said condition needs to be applied before
replicate(...(replicate(...(sum(...))) takes place.
