fitting a mixture of distributions with optim and max log likelihood ?
...warnings() to see them)
Questions:
1) Did I mess up anything in the formulae?
2) Any suggestions for converging to the same value?
3) Any suggestions for other methods to get means, stddevs and proportions of the mixture of distributions?

dxf() like bmp() or postscript()?
...ogical
sufaces and it would be handy to be able to dump a plot as an autocad dxf
file for vector import into autocad. A search of rhelp of 99 thru 01 gave no matches for dxf. Any suggestions for a dxf or dump of a plot as vectors?

Performance note: Preallocating helps? and two questions
...for(i in 1:length(AU))AUcap30[i]<-min(30,AU[i])
is very quick (a few seconds)
Is this performance difference common in r (ie is linux the same way)?
Are there other tricks to speed up R (in windows) (besides a faster processor and more memory)?

R under Win2000?
Dear all,
Will R run under Win2000 or is it safer to stay with NT4.0 for a while?

Re: R 0.90.0 for Windows rwinst fails (for me) and workaround
...ded r 0.90.0 for windows and ran rwinst.exe and the base package would not install for me. I had to unzip
rw0900b1.zip and r20900b2.zip manually and then do the rest of install with rwinst. Is this due to b being replaced
by b1 and b2?

percentile labels in qqnorm
...0,30,50,70,90,95,99)
axis(1,at=qnorm(l/100),label=l)
which was ok for this data set.
Does anyone have a more general solution which would allow one to
specify the number of x labels and then "pretty" choose the label values
and plot them?

getting a windows environment variable in r
hi-
I would like to get a value set with the dos set command (e.g. set dog=cow) in a rterm session on rterm 1011 under windows 2000. if I try in a dos window:
set dog=cow
echo %dog%
i get cow (what I want)
then i start rterm
system("echo %dog%",intern=T)
gives "%dog%"
I can of course do something like
set dog=cow
echo %dog% >jnk.rin
and then start rterm and

outlier detection methods in r?
hi -
if I sample from a normal distribution with something like
n100<-rnorm(100,0,1)
and add an outlier with
n100[10]<-4
then
qqnorm(n100)
visually shows the point 4 as an outlier
and calculating the probablity of a value of 4 or bigger in 100 samples of norm(0,1)
gives
> 1-exp(log(pnorm(4,0,1))*100)
[1] 0.003162164
If I have more than 1 sample above outlier threshold the math is a

Summary :Re: 1.2.2 under M$ windows 2000 lots of plots out of memory?
hi list-
Under windows 2000 I was asking for more than the 256MB limit. solutions (and first suggester) were:
1) Reading the rw-FAQ and ?Memory for memory management under 1.2.x. (Prof Brian Ripley) <- this is the one I should have used
2) Run with P:\r\base\rw1022\bin\rgui.exe (Thomas Lumley) <-this is one I used
3) use gc() (Joerg Polzehl) <this is handy
Thanx to the list

implementing a foreign system with system?
Hi-
There is a public doman geostatistics package used in the minieral industry called GSLIB and I would like to use it from R. However it is fortran (but portable and easy to compile on windows and linux)and has its own file format and control file format. It seems easiest to write an r function to dump r data to an ascii file, build a control file in ascii; call the GSLIB program with
