engineering notation format
Hi,
How can I format numbers to engineering notation?
That is, like scientific but where the exponent is always a multiple of
three.
Some examples:
1635 000 000 => 1.635E9
163 500 000 => 163.5E6
0.000 000 000 135 => 135E-9
I've tried format and formatC but I couldn't get them to work they I
want.
Any help is greatly appreciated.
Thanks,
Sam

Install rgdal, lazy loading error
Hi all,
I have successfully made and installed both gdal, and proj.4, but still
cannot get rgdal to be installed in R. I think i'm very close. I do not
have root access, if that matters, i've installed everything locally. I'm
using debian on a beowulf cluster.
I call:

How to Reshuffle a distance object
I would like to randomly shuffle a distance object, such as the one
created by ade4{dist.binary} below. My first attempt, using
sample(jc.dist) creates a shuffled vector, losing the lower triangular
structure of the distance object. How can I Ishuffle the lower
triangular part of a distance matrix without losing the structure?
Thanks. --Dale

avoid using Dingbats symbols for points()
Hi,
I came across with a tiny problem.
E.g.:
pdf()
plot(1:5)
points(2, 3, cex=10, pch=21, bg="grey", lwd=0.3)
points(2, 4, cex=1, pch=21, bg="grey", lwd=0.3)
dev.off()
If I execute this I'll get a nice PDF. Fine.
But I want to edit this PDF with let's say by using Adobe Illustrator.
If I try to open it Illustrator shows up an error message:

diagnostic information in glm. How about N of missing observations?
I handed out some results from glm() and the students ask "how many
observations were dropped due to missing values"?
How would I know?
In other stat programs, the results will typically include N and the
number dropped because of missings. Without going back to R and
fiddling about to find the total number of rows in the dataframe, there
is no way to tell. Somewhat

configure statement for R-devel with updated zlib in user account
I'm aware R-devel no longer includes zlib. This works find on
up-to-date Linux systems.
On the older Centos 6 cluster at KU, they have zlib tool old for
R-devel. The R-devel configure fails thus:
checking if zlib version >= 1.2.5... no
checking whether zlib support suffices... configure: error: zlib
library and headers are required
In other software, I've seen this kind of thing, so

text vector clustering
Hi,
I am a new user of R using R 2.8.1 in windows 2003. I have a csv file with
single column which contain the 30,000 students names. There were typo
errors while entering this student names. The actual list of names is <
1000. However we dont have that list for keyword search.
I am interested in grouping/cluster these names as those which are
similar letter to letter. Are there any

Permutation of a distance matrix
Hi there,
I would like to find a more efficient way of permuting the rows and columns of a symmetrical matrix that represents ecological or actual distances between objects in space. The permutation is of the type used in a Mantel test.
Specifically, the permutation has to accomplish something like this:
Original matrix addresses:
a11 a12 a13
a21 a22 a23
a31 a32 a33

Proposed change in file.exists() to tolerate Windows
I'm writing to ask if R Core would make file.exists more Windows
tolerant when the argument has a trailing slash. This has been
discussed by users a few times here, I know it is not a new topic. But
it is not a solved problem, yet. I acknowledge that CRAN packages
exist which fix this by replacing file.exists(), but it seems more
elegant to me to fix the problem in R itself.

Overall p-value from a factor in a coxph fit
Hi all.
If I run the simple regression when x is a categorical variable ( x <-
factor(x) ):
> MyFit <-coxph( Surv(start, stop, event) ~ x )
How can I get the overall p-value on x other than for each dummy
variable?
> anova(MyFit)
does NOT provide that information as previously suggested on the list.
All the best,

Plot and Boxplot in the same graph
Hii,
Is it possible, to use the plot() funktion and the boxplot() funktion
together ?
I will plot a simple graph and additionally to the graph on certain places
boxplots. I have imagined to plot the graph a little bit transparency and
show in the same graph on certain places boxplots....
Is it possible to do it in this way ?

Sweave documents have corrupted double quotes
I'm attaching a file foo.Rnw and I'm hoping some of you might run it
through your R & latex systems to find out if the double-quotes in
typewriter font turn out as black boxes (as they do for me). If you
don't use Sweave, but you have a system with a working version of R
and LaTeX, the file gives the instructions you need to use to process
the file. The

Converting coordinates to actual distances
Hello,
I've been searching for a method of converting Lat/Lon decimal
coordinates into actual distances between points, and taking into
account the curvature of the earth. Is there such a package in R? I've
looked at the GeoR package, but this does not seem to contain what I am
looking for. Ideally the output would be a triangular matrix of
distances.
Thanks in advance,

how to make plotmath expression work together with paste
Recent questions about using plotmath have renewed my interest in this question
I want to have expressions take values of variables from the
environment. I am able to use expressions, and I am able to use paste
to put text and values of variables into
plots. But the two things just won't work together.
Here is some example code that shows what I mean.
plot(NA,xlim=c(0,100),ylim=c(0,100))

Please explain your workflow from R code -> package -> R code -> package
Hi,
I'm asking another one of those questions that would be obvious if I
could watch your work while you do it.
I'm having trouble understanding the workflow of code and package maintenance.
Stage 1. Make some R functions in a folder. This is in a Subversion repo
R/trunk/myproject
Stage 2. Make a package:
After the package.skeleton, and R check, I have a new folder with the

Care to share an R presentation?
The R movement is picking up steam in the center of America. People
that ignored my R-enthusiasm 10 years ago are now calling me up asking
for presentations. I need to make a 2 hour presentation to a
collection of faculty and grad students who might like to use R. I
don't want to make it seem too complicated (as I often do), but I
don't want to mislead them to think it will be easy.

Tinn-R
I am new to R and have recently tried Tinn-R with very mixed and unexpected
results. Can you point me to a Tinn-R tutorial on the web or a decent
reference book?
