Scientific notation?
Hi,
Would there be a function and/or some options to force R to write a value of
say 1.0e-4 as "0.0001"? More specifically I want to use R to write ASCII
file(s) for other programs to read and some of these programs don't know how
to deal numbers in scientific notation or have a different convention.
Thanks in advance.

Rcmd ?
Hi,
I tried running Rcmd.exe to no avail. It doesn't even start because it tries
to read some memory address that NT says it can't and terminate.
I tried downloading and reinstalling rw1020sp.zip with the installer twice
just in case it got corrupted somehow in transport but it resulted in the
same problem.
What should I do?

Redrawing !
Hi,
If I may suggest that something be done to the window drawing function of a
plot. As it is now, we don't even have time to resize the window by a tiny
bit before it's invoke and I think it would be an improvement if while the
mouse is down the redrawing was delayed somehow. This is especially true
when the plot is crowded. I also observed that moving the plot window around
was a lot

Cleaning things up?
Hi,
I know it must be written somewhere but I can't find it.
I'd like to remove all variables or objects that I've created but not the
functions. I look at a few things without success. Is there a R way of doing
this? There are to many to create a manual list.
Thanks in advance.

How to?
Hi,
Is there a way to apply a function to rows or columns of a matrix?
Now I use apply(as.matrix(1:nrow(m), 1, function(x) mean(m[x,])) which works
fine but kind of slow on large matrix. I'm sure there is something on this
somewhere but I can't find it.
Thanks

Principal component?
Hi everyone,
I did a principal component analysis (princomp) on a dataset I have, I
plotted the first two columns and labeled the points by their index number.
I observed that most index sequences (points 50:65 for example) kind of form
arc shape trajectories on the graph (even loops), some of those seem to
converge at some particular location and those specific patterns just happen
to have some

Folding ?
Hi,
I need to write a function that would look something like this:
S <- function(b=betas){
expression(b[1] * f(b[2] * x * f(b[3] * x * f(...b[n-1] * x * f(b[n] *
x)))...)
}
Where n is the number of element in b.
Further I need to be able to evaluate S at some x numerically of course and
I need to use "deriv" and produce dS/dx such that I can evaluate it also at
some x.

Sorry to ask this but what is the meaning of "AFAIK". From a darn Frenchman!

Rcmd
I'm running Windows NT4. Rcmd does not seen to
read the command line. Rterm and other things work
well. For example "Rcmd check --help" fails with
the command interpreter trying to find a program
or file called "check." What have I missed?

Filled region on graph
Hi,
Say I'd like to fill in color or by hashing the region above 0.5 and
below -0.5 in the following situation.
> x <- seq(0,2*pi, length=100)
> plot(x, sin(x), type="l")
> # Now fill the top part and the bottom part
The only mention of the words "fill" or "filled" seem to be in
filled.contour.
So is this possible in R?
Thanks in advance.
