R hangs sometimes and crashes (PR#429)
Full_Name: Kjetil Kjernsmo
Version: 0.65.1
OS: Digital UNIX 4.0
Submission from: (NULL) (129.240.28.172)
I have the following R code:
ncloudsbin <- function(binno, ntotalclouds, numberofbins = 100, linewidth =
numberofbins / 6)
return(ntotalclouds * dnorm(binno, sd = linewidth))
photonsincidenttodetectorbin <- function(binno, ntotalclouds,
avgphotonfromcloud, ampmode = 1, ampmean = 2, numberofbins = 100, linewidth =
numberofbins / 6)
{
sc <- ampmean - ampmode...

rpois gives a large number repeatedly (PR#439)
...really
strange because a poisson distribution with a parameter of 3 shouldn't see the
number 1932 very often, but the same, incredibly high number is drawn
repeatedly.
These are the two relevant functions, the latter somewhat expanded for debugging
purposes.
ncloudsbin <- function(binno, ntotalclouds, numberofbins = 100, linewidth =
numberofbins / 6)
return(ntotalclouds * dnorm(binno, sd = linewidth))
photonsincidenttodetectorbin <- function(binno, ntotalclouds,
avgphotonfromcloud, ampmode = 1, ampmean = 2, numberofbins = 100, linewidth =
numberofbins / 6)
{
sc <- ampmean - ampmode...

Problem with match.arg() (PR#536)
...roduce, I just did 100000 runs of ramp(10000, "point")
directly with no problems. In my code, ramp is called by a function that is
called
by a function, that is... :-)
However, the code isn't very involved, really, so if you want to try, here it
is:
ncloudsbin <- function(binno, ntotalclouds, numberofbins = 100,
linewidth = numberofbins / 6)
return(ntotalclouds * dnorm(binno, sd = linewidth))
intensityfromcloud <- function(ncloudsbin, cloudintensity, exptime, amptype)
return(cloudintensity * exptime * ramp(ncloudsbin, amptype))
photonsdetectedbin <- f...

Package GSS for interpolation in more than 2D?
...est case, I have two data.frames: For each of the data.frames
The three first coloumns make up a 3D grid (I'd like to go up to at least
5), and the fourth coloumn contains the values for the point specified in
the first three.
The smaller data.frame, may have been generated by e.g.
expand.grid(ntotalclouds=seq(1000000, 12000000, length=2),
EW=seq(8,25,length=3),
numberofbins=seq(100, 1000, length=3))
while the larger data.frame may look like
argsspacex50 <- expand.grid(ntotalclouds=seq(1000000, 12000000, length=6),...
