Vis5D interface package
....e., F(x,y,z,t). [It's also GPL'ed and compiled
beautifully on a RH Linux 7.1/Intel machine]
The files I have so far are:
(1) FORTRAN code + header file for converting an ASCII file into Vis5D
`v5d' format (Note: compilation needs the Vis5D libraries).

http://socrates.berkeley.edu/~nklepeis/Vis5D/v5df.h
(2) R function for fitting f(x,y,z) data across different times (using
the `Tps' Kriging function in the R `fields' package), calculating
function values across a *regularly*-spaced grid, and outputting an
ASCII file that c...

Weighted Histogram

Thanks,

some related problems
I just tried to batch-start rgui.exe (not rterm.exe) in a way, that it
read.table()s data from a file with changing filename. As I understand no
command line parameters are available for that, so instead I tried to pass
the filename to an approbriate .RProfile, which works roughly, BUT
## this is my %R_USER%\.RProfile

Tps regression question
Dear all,
I'm a beginner in spatial regression, therefore, excuse me in advance for
the stupid question.
I'm using the function Tps of field library. As I read in help, the
assumed model for this regression is additive Y = f(X) + e where f(X)
is a d dimensional surface.
I have understood that d in not an argument to specify in Tps(x, Y, ...).
How can I obtain d ?
Thanks a lot.

Reading multi-line FWF data
...and let me
know of any problems.
Also, is there another (better) way to do this in R?

Graphics output device
Dear developers,
I wonder would you consider making a save to a graphics file format (as opposed
to ps)?
What prompts this is that we have just finished my wife's thesis using R
heavily for stats and graphs. The combination of latex, bibtex and R generated
.eps worked a treat and we were very pleased with both the final outcome and
the efficiency of gernerating it, especially when all the

Transpose and NA's
I noticed some odd behavior when I transpose a data frame containing
NA's. It seems to cast all the elements as "character" including the
NA's. Bug?

Limit on Function Size
With R 1.5.1 (Linux/Intel), I noticed that one of my large functions
(>3000 lines) can no longer be parsed. Somewhere around 2800 lines, R
will segfault when I `eval(parse(file="..."))' the function.
I can parse the lines after around line 2800 by themselves (i.e., cut
and pasted).
Is there some new limit on the size of R functions?

Zero is not Zero
I have a confusing problem with getting the form `x - trunc(x)' to be
exactly zero when `x' is an integer. It only seems to occur inside of a
function. [R-1.6.0 on Linux/Intel]
I have a function to return the highest precision digit of values in `x':
prec<-function(x){
init <- trunc(log10(max(x)))
y <- x - trunc(x)
while (any(y > 0)) {
init <- init - 1
