How to do this "combination" ?
Thanks David first.
Probably, David misunderstood my points.
source vector = (1,2)
the length of the target vector = 3
My expected "complete" outputs should be:
111, 112, 121, 122, 211, 212, 221, 222.
sample(c(1,2),3,replace=TRUE) just gives me one "randomly sampled"
combination at a time. However, I need the whole list displayed above at a
time.

./configure --prefix and R_LIBS
Hi!
I am installing R in non standard directory.
./configure --prefix=/non/standard/directory
The installation works fine.
But after starting R i get
.libPaths()
/usr/lib/R/library
but they cant be there of course!
Have I to set some additional switches during config?

customising installed libraries
hello
I am returning to some libraries that I had previously customised by amongst
other things adding additional functions. I had simply typed these new
functions into the file in library/R/thelibrary. These however do not seem
to be loaded now as they previously were under older versions of R.
What's changed and what do i need to do?
Thanks

Bug? using { as a function in lapply
This seems like a bug to me. Can someone verify this?
First we define a function f that returns its second argument and
lapply it to 1:2 using 9 as the second argument and all seems well.
Note that "{" as a function does the same thing as f, as illustrated
with f(1,9) and "{"(1,9); however, when we attempt to use "{" in the
very same way we used f in lapply,

Is there a way to represent the ... argument in signature?
Hi!
I guess that it cant work. but maybee I am wrong.
I would like to define a function rbind.
> rbind
function (..., deparse.level = 1)
{
which works only for objects of class Myclass
Is it possible to use something like
setMethod("rbind",signature(...="Myclass",deparse.level="numeric")
This gives an error.
Or should I use
rbind.Myclass

method names conflict.
Hi!
I would like to give my objects functions like "subset", "union", et cetera and name it also in this way.
But this functions names are already used in the base package and they are not generic.
I am right in that if they would be generic then i still can use the neat names with my objects?
I have the impression that there are more and more packages are going to be

variable definition
Hello All:
This function obviously fails
x <- function(z) paste("go", z, sep = ".") <- 10
x("now")
But is there a way to define the name of a variable through passing a
parameter in a function call?

scatterplot of 100000 points and pdf file format
Hi,
I want to draw a scatter plot with 1M and more points and save it as pdf.
This makes the pdf file large.
So i tried to save the file first as png and than convert it to pdf.
This looks OK if printed but if viewed e.g. with acrobat as document
figure the quality is bad.
Anyone knows a way to reduce the size but keep the quality?

XML Package.
Hi!
I have installed the new R on windows.
I wanted to reinstall the XML package. I am not able to find the XML.zip anymore. I am quite shure that they where a windows binary version.
Has anyone old XML windows binary?

2 images with 2 color scales on one graphic device. How to get it?
Hi!
Would like to plot two image plots with color scale (like levelplot (lattice) implements) in one graphic device.
Tried to plot 2 levelplot's (lattice) (the data has not much in common) in one graphics device by setting par(mfrwo=c(2,1)) which does not work.
Is there a way to force levelplot to use only a half of the graphic device?
Is there a function like image which provides the color

empty string
Hi!
How to generate a empty string of a precise length without using a loop?
I need a empty string (char **) to pass it with .C function to a c dll. The c routine writes the result into the string.

plot.dendrogram and plot.hclust ZOOM into the height?
Hi,
I clustered a distance matrix and would like to draw it using
plot.hclust or plot.dendrogram.
The dendrogram is not informative because I have a few extremely small
dissimilarities in the distance matrix (e.g. 0), but most of the other
distances are in the range 1e10+-5000.
I would like to show the tree only for the height of 1e10+-5000 but
unfortunately their are no parameter like

How to add values to an array at any position.
Hi,
How to add values to an array at any position.
Asking because of the following:
e.g.
y<-c(0.1,NaN,0.2,NaN) #or data frame
x<-na.omit(y)
take some columns from x and
do some computation with functions which do not allow NaN 's.
After the computing add NaN's at positions stored in
attr(x,"na.action")
of the result vector.
