How to modify the values of the parameters passing via ...
Dear Friends,
Let's assume there are three parameters that were passed into fun1. In
fun1, we need to modify one para but the remains need to be untouched. And
then all parameters were passed into fun2. However, I have failed to
achieve it.
Please see the following code.

fun1 <-function(x, y, z=10) {x+y+z;}
fun2 <-function(aa, ...) {

objects and environments
Dear list,
I have two functions created in the same environment, fun1 and fun2.
fun2 is called by fun1, but fun2 should use an object which is created in fun1
fun1 <- function(x) {
ifelse(somecondition, bb <- "o", bb <- "*")
## mymatrix is created, then
myresult <- apply(mymatrix, 1, fun2)
}
fun2 <- function(idx) {

mlocal/mtrace inside a loop
Hello
I need some help in figuring Bravington’s debugger
out.
Ok
I have 2 functions, fun1 and fun2 saved in a ASCII
file say filename is funs.
Fun1 has a loop which calls fun2, fun2 has a loop
which fails and I need to find out the value of the
variables of the fun2 and fun1 loops at the specific
iteration that fails. Both fun1 and fun2 loops will
iterate thousands of times so line by line debug

emacs, Mac OS X, R
Hi!
Since August I am using emacs on my Macintosh to edit the R objects. I
have installed R 1.9.1, Mac OS X 10.3.5 and GNU Emacs 21.2.1. However
there are some issues I haven't resolved:
a) switch the caps lock key to the meta key (and when this is not
possible, switch the alt/option key to the meta). The switch should
work only within emacs!
b) having different colors for the code,

Two functions as parametrs of a function.
Hi R users:
I'm trying to make a function where two of the parameters are
functions, but I don't know how to put each set of parameters for
each function.
What am I missing?
I try this code:
f2<-function(n=2,nsim=100,fun1=rnorm,par1=list(),fun2=rnorm,par2=list()){
force(fun1)
force(fun2)
force(n)
p1<-unlist(par1)
p2<-unlist(par2)
force(p1)
force(p2)

pass "..." to multiple sub-functions
Dear list,
I know I have seen this discussed before but I haven't been successful
in searching for "ellipsis", "dots", "..." in the archives. I would
like to filter "..." arguments according to their name, and dispatch
them to two sub-functions, say fun1 and fun2. I looked at lm() but it
seemed more complicated than I need as it modifies the calling

package NAMESPACE question
Hello,
I'm building a package. My code is stored in foo.R. This code has two
functions FUN1 and FUN2. FUN1 calls FUN2. FUN1 is listed in export() under
the package NAMESPACE but NOT FUN2. After building the package when I call
FUN1 is giving me an error that cannot find FUN2.
I solved this by adding FUN2 in the export() NAMESPACE. However, what is
puzzling me is that I have other examples

Problem with the special argument '...' within a function
I'm not sure if this is what you want, but simply add ... to the list of
arguments for fun1 and fun2 would eliminate the error.

correct function formation in R
Dear list!
?
I have question of?'correct function formation'. Which function (fun1 or fun2; see below) is written more correctly? Using ''structure'' as output or creating empty ''data.frame'' and then transform it as output? (fun1 and fun1 is just for illustration).
?
Thanks a lot, OV

integrate with large parameters
Dear R-users,
i have to integrate the following function
`fun1` <- function (a, l1, l2)
{
exp(log(l1) * (a - 1) - l2 * lgamma(a))
}
but if l1 is large, i get the "non-finite function value" error, so my
idea is to rescale with exp(-l1)
`fun2` <- function (a, l1, l2)
{
exp(log(l1) * (a - 1) - l2 * lgamma(a) - l1)
}
but it seems this doesn't solve the problem, when

ifelse(is.na), with function inside
Hi,
I have a vector a=c(NA, 3, 4, 4, NA, NA, 3) and I would like to use is.na(a)
function to get a vector like this:
wy=(1,2,2,2,1,1,2) - you know, this vector create 1 or 2 depends on value in
vector "a"
This is my short code but something is wrong and I don't know what...

a=c( NA, 3, 4, 4, NA, NA, 3)

x=1

storing the results of an apply call
Hi R-users,
I have a function (myfun) that I want to apply to the rows of a matrix.
Basically, "myfun" takes the values from the matrix ("exp.des"), which
represent the different combinations of my experimental design, and pass
them as arguments to some other functions (fun1 and fun2). As I want to
replicate the results of fun1 and fun2 a certain number of time (e.g.
5), I

transform input argument (matrix) of function
Dear list!
I would like to write a function to transform matrix, which is input argument of a written function. It is easy with new matrix (see below), but my idea is to transform input argument (matrix) of function without any additional matrixes. Here is an example:
fun1 <- function(xy) {
xy <- cbind(xy[,1], xy[,2], xy[,1] + xy[,2])
return(xy)
}
df1 <- matrix(c(1,2,3,1,2,3), ncol =

Under current semantics, yes. Each 'stream' of function calls is lazily capturing the last value of `i` on that core.
Under Luke's proposed semantics (IIUC),
the result would be the same (2,4,6,8) for both parallel and serial execution. This is

`match.call` and dots substitution
I'm noticing some interesting behavior in `match.call` in some corner-ish cases that arise when you try to use `match.call` to match a "grandparent" function and there are dots involved:

fun1 <- function(b, ...) fun2()

update() can not find objects (PR#1861)
Full_Name: Yi-Xiong Zhou
Version: 1.5.1
OS: win2000pro
Submission from: (NULL) (64.169.249.42)
Update() can not find objects when it is used in a function, which is in turn
being called by another function. Here is a R script to show the problem:
######## begin of the test script ##########
fun1 <- function() {
x <- matrix(rnorm(500), 20,25)
y <- rnorm(20)

Preserving output of MCMC iterations
Dear colleagues,
I'm an epidemiologist with no background in programming and just

Resources for utilizing multiple processors
Hello,
I know of some various methods out there to utilize multiple processors but
am not sure what the best solution would be. First some things to note:
I'm running dependent simulations, so direct parallel coding is out
(multicore, doSnow, etc).
I'm on Windows, and don't know C. I don't plan on learning C or any of the
*nix languages.
My main concern deals with Multiple

[PATCH 09/23] nv50-: separate vertex formats from surface format descriptions
Why not fix the new names instead to be like the old names? Seems like that
would be way simpler...
