install/build/build --binary
I have question regarding package installation.
What is the difference between check, INSTALL, build and
build --binary, which imply which and what order does one
normally perform them? I have been trying:
R CMD build /mypackage
R CMD check /mypackage
R CMD build --binary /mypackage
in that order but wanted to check that this is right.
Also, what portion of the check process can be run

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?

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

substitution in expression
I have been struggling with this problem for a while and I hope someone
could help me. Or if someone could point me to a section in the manual I
would be grateful.
x <- "my"
plot(1:10, main=expression(paste( x, Delta, "values" )))
Q : How do I get the title to say "my (triangle symbol) values" ?

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)

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".
If I call this function

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.

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.

I am installing R in non standard directory.

The installation works fine.
But after starting R i get

Have I to set some additional switches during config?

C/C++
Hey everyone,
I have been looking for a while for ways to integrate R's wonderful
functions into my C++ software, but I have not found anything
concrete.
So finally, i post to this list to see if anyouse else knows about
this, or has done it!? Is it possible? Are there C++ or C R libraries?
Or is it sufficiently easy to build them?
your help is much appreciated!
thanks

Need your help with my R plot
Hi,
I am using R to plot the graph and the problem I am facing with my graph is that I have lots of points concentrated in one area and It is creating a visualization challenge.
Is there any commands in R I could use to solve this problem. Even if there is no command, do you know how I could tackle this problem...(I want to separate these points so I could see each of them...)
Any help is much

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

More efficient matrix computation
I have a 20x3 matrix as follows:
> m <- replicate(3, matrix(rnorm(20),20,1))
I need to compute, say, 95th and 99th percentiles of
each column such that the resulting matrix becomes 2x3
with each row representing the respective percentile.
My "best effort" is to compute one column at a time as
follows:
> quantile(m[,1], c(0.95, 0.99))
To do the same for columns 2 and 3, I

I am trying to write an article for the Rnewsletter, but keep getting

Sweave echoing comments (again)
Hello,
I try to document some R scripts for my collegues and observed the
problem, that Sweave strips comment lines away.
As a small example I write in an Rtex file:
\begin{Scode}
## a small example
test() # line comment
\end{Scode}
... the .tex file generated by Sweave only contains:
\begin{Schunk}
\begin{Sinput}
test()
\end{Sinput}
\end{Schunk}
... and all the comments are lost.
