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

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,

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

./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()

but they cant be there of course!
Have I to set some additional switches during config?

Hiding internal package functions for the doc. pkg-internal.Rd
Hallo!
I would like that the internal package functions does not appear in the documentation.
I placed they names as aliases in the file nameofmypackage-internal.Rd as advised.
After R CMD check (which runs neatly) they are still listed in 00Index.html.
Is there no way to hide internal functions from the doc?
Have I overlook something?
Sincerely Eryk.

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

could help me. Or if someone could point me to a section in the manual I
would be grateful.

Q : How do I get the title to say "my (triangle symbol) values" ?

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?

gplot.hexbin - how to set figure margin.
Hi,
Would like to use to the hexbin package to plot a 2D hist - because it looks really _cool_.
My problem is related to drawing a pdf hexbin graphic in series of other graphics.
All other figures have a par(mar=c(3.2,3.2,1,1)). So the gplot.hexbin figure in this series looks a little alienated?
Was trying a to specify the _mar_ using par, viewport, hexViewport etc. a little.

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?
Thanks,

Ordering of values returned by unique
Hi,
Is the ordering of the values returned something on what I can rely on,
a form of a standard, that a function called unique in R (in futher
versions) will return the uniq elements in order of they first occurcence.
> x<-c(2,2,1,2)
> unique(x)
[1] 2 1
Its seems not to be the standard. E.g. matlab
>> x=[2,2,1,2]
x =
2 2 1 2
>> unique(x)

question about hierclust {multiv}
my major is bioinformatics, and i'm trying to cluster ( agglomerate
the closest pari of observations ) in R.
i have already got my own similarities metric, but do not know how to
clust it based on similarities instead of dissimilarities.
since the help document of hierclust mentions the parameter "sim",
which seems good to me, but it doesn't appear in the code of

Function _coerce_ in _setIs_ never entered (S4).
Hi,
Please consider the following trivial example.
In the sample code I first define a class MVCa using composition. This
class contains a slot of type list.
Next I define an inheritance relation using the function setIs -> MVCa
"is a" list.
Then I define a function printlength which prints the list-length which
is defined for the type "list".

problems with starting R
When I try to start R from my desktop, an "information"-window pops up:
"Fatal error: Invalid HOMEDRIVE".
I already deleted and reinstalled the program, but the problem lasts.
How can I solve this problem?
I would be very glad, if you can give me a hint, what??s going wrong.

Stats package
Hi
The cor function in the stats package calculates the correlation between
columns of data, does anyone know if it is at all possible to calculate
the correlation between rows instead ?
Or is there an appropriate package or function that is more appropriate
I'd like to calculate spearman & pearson correlations between rows.
Many thanks
Jason
