Hallo! I want to plot multiple grouped data in a postscript file using a loop. As I use a loop no plot (or just one empty plot) is generated. Here an example: library(nlme) data(Loblolly) # example data from nlme postscript("PSFile.ps") for (i in 1:1) # just as example { plot(Loblolly) } dev.off() Result: Just an empty PSFile.ps. (Withoput the loop it works. May anybody help? Karl

Michael Lapsley was suggesting on R-help direct copies to gif/png/jpeg. The following seems to do a sensible job for me of copying the current device to any bitmap format supported by gs. The manipulation is needed to work around assumptions made by postscript(), and I think better fixed in postscript() (but not a couple of days before a release). I want to make onefile=FALSE work on

Hi. I have a function that works well under R 1.7.1 But under 1.8.0 and 1.8.1 I get:Warning message: calling par(new=) with no plot And it doesnt plot The function is: mplotmeth1<-function(data1,data2,alpha,nr){ psfile<-paste("Meth1_",nr[1],"-",nr[length(nr)],".ps",sep="") postscript(psfile) close.screen(all=T) par(mex=0.73,cex=0.8)

Hi, Is it possible to set up a printer in samba that will use ps2pdf converter to create pdf documents when printing on it ? Best Regards Steph

Hello R users, This question might be already discussed before, I apologize if it is the case. Simple... how can I do to include a figure in a latex document. As I have already done in Splus, I tried this: \begin{figure} \special{psfile=gauss.ps .......} \end{figure} but it didn't work. Any help? Thank you in advance. PS: I let down the Mac and the MS Window platforms and I am back to my

Hi. I just noticed the paper by Morales and Nocedal Remark on "Algorithm 778: L-BFGS-B: Fortran Subroutines for Large-Scale Bound Constrained Optimization". TOMS 2011; 38(1): 7 http://www.ece.northwestern.edu/~morales/PSfiles/acm-remark.pdf which describes a couple of improvements (speed and accuracy) to the original Netlib code which AFAICT is that still used by optim() via f2c. Updated code is under http://www.ece.northwestern.edu/~nocedal/lbfgsb.html released under the New BSD License. Has this already been ma...

Hello: The development version of Ecdat on R-Forge contains a vignette in which optim(?, method=?L-BFGS-B?) stops with an error message while violating the lower bound. To see all the details, try the following: install.packages("Ecdat", repos="http://R-Forge.R-project.org") Then do "help(pac=Ecdat)" -> "User guides, package

We are currently using Rsync (with cygwin) to propagate static files from a preview server (Windows) to our live servers (Windows) on demand. Unfortunately, because the live servers are *live*, inevitably some of the files we mean to update are in use and therefore locked by the windows filesystem. Since they are locked, they are not updated, and our servers get out of synch. Does anyone know

Hello, I have samba 3.20 running in test on Solaris 8 and 9 beautifully it is curently configured as a Domain Client it authenticates using winbind and nsswitch libraries using ADS with windows 2003 server. I have krb5 and ldap working just fine but I now find myself with a mess of bugs and questions and I could really use some of your expertise in the matters so here they go, Thank you soooo

Hi all, After a long time having no time, I have finally done some fresh work on my software fax machine. I have replaced the original carrier tracking with something more robust. I have also added 4800, and 2400 bits per second modes, and cleaned up a few bugs in areas like superfine mode operation. I apologise for this update taking so long.
