Thank you, Duncan, it works now with rgl.snapshot (i did have to upgrade to 2.12.1). Is there any way to manipulate the size of the created image? The created plots are a bit small (256*256)
Sure, they're the size of the window: it's just a snapshot. Just make it bigger (by mouse, or using par3d(windowRect= ...)) before taking the snapshot.

Thank you for your help once again :) Best, Jurica On Tue, Jan 4, 2011 at 8:31 AM, Duncan Murdoch <murdoch.dun...@gmail.com <mailto:murdoch.dun...@gmail.com>> wrote: On 03/01/2011 8:17 PM, Jurica Seva wrote: Hi, I have been trying to output my graphs to a file (jpeg, pdf, ps, it doesnt matter) but i cant seem to be able to get it to output. As Uwe said, you are using rgl graphics, not base graphics. So none of the standard devices work, you need to use the tools built into rgl. Attach that package, and then read ?rgl.postscript (for graphics in various vector formats, not just Postscript) and ?rgl.snapshot (for bitmapped graphics). Some notes: - For a while rgl.snapshot wasn't working in the Windows builds with R 2.12.1; that is now fixed, so you should update rgl before getting frustrated. - rgl.snapshot just takes a copy of the graphics buffer that is showing on screen, so it is limited to the size you can display - rgl.postscript does a better job for the parts of an image that it can handle, but it is not a perfect OpenGL emulator, so it doesn't always include all components of a graph properly. Duncan Murdoch I tried a few things but none of them worked and am lost as what to do now. I am using the scatter3d function, and it prints out the graphs on tot he screen without any problems, but when it comes to writing them to a file i cant make it work. Is there any other way of producing 3dimensional graphs (they dont have to be rotatable/interactive after the print out)? The code is fairly simple and is listed down : #libraries library(RMySQL) library(rgl) library(scatterplot3d) library(Rcmdr) ############################################################################## #database connection mycon<- dbConnect(MySQL(), user='root',dbname='test',host='localhost',password='') #distinct sessions rsSessionsU01<- dbSendQuery(mycon, "select distinct sessionID from actiontimes where userID = 'ID01'") sessionU01<-fetch(rsSessionsU01) sessionU01[2,] #user01 data mycon<- dbConnect(MySQL(), user='root',dbname='test',host='localhost',password='') rsUser01<- dbSendQuery(mycon, "select a.userID,a.sessionID,a.actionTaken,a.timelineMSEC,a.durationMSEC,b.X,b.Y,b.Rel__dist_,b.Total_dist_ from `actiontimes` as a , `ulogdata` as b where a.originalRECNO = b.RECNO and a.userID='ID01'") user01<- fetch(rsUser01, n= -1) user01[1,1] #plot loop for (i in 1:10){ userSubset<-subset(user01,sessionID == sessionU01[i,],select=c(timelineMSEC,X,Y)) userSubset x<-as.numeric(userSubset$X) y<-as.numeric(userSubset$Y) scatter3d(x,y,userSubset$timeline,xlim = c(0,1280), ylim = c(0,1024), zlim=c(0,1800000),type="h",main=sessionU01[i,],sub=sessionU01[i,]) tmp6=rep(".ps") tmp7=paste(sessionU01[i,],tmp6,sep="") tmp7 rgl.postscript(tmp7,"ps",drawText=FALSE) #pdf(file=tmp7) #dev.print(file=tmp7, device=pdf, width=600) #dev.off(2) } ______________________________________________ R-help@r-project.org <mailto:R-help@r-project.org> mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
