Hi. I'm running R OS X GUI 1.35-dev Leopard build 64-bit. When I run the following code (snippet from a larger code) from the GUI I obtain 2 separate *.pdf files as you would expect from the high-lighted code. However, when I run from Rscript (command-line), I only get the first one. No errors appear in the console log however I do get a 'null device' message that I don't understand. It's probably related but I have no clue how to debug this. Perhaps the second output file is not getting initialized? I've tried a few variations to see if I can unearth the cause but no joy so far. Any suggestions would be appreciated.
Thanks. ... profiles.spl <- smooth.spline(x, y) (profiles.spl) x_pred = seq(1,as.integer(max(x))) B = data.frame(predict(profiles.spl,x_pred)) pdf(file=paste("/Volumes/SLR_Data_001/USN_SERDP_SLR/data/level1/beach_profiles_Flick/",Filename,".pdf",sep="")) caption = paste(aLocation," (", aYear,".",aMonth,".",aDay,")",sep="") credits = paste("splineWriter.R / hel...@ucsd.edu / 20110120") xrng = range(x) yrng = range(y) pred = qplot(x,y, data=B, xlab="Distance (m)", ylab = "Elevation (m)", xlim=c(0,1000), ylim=c(-12,4)) pred + geom_text(aes(700,2,label=caption)) + geom_text(aes(180,-12,label=credits),size=2.7) dev.off() ## Residual (Tukey Anscombe) plot: pdf(file=paste("/Volumes/SLR_Data_001/USN_SERDP_SLR/data/level1/beach_profiles_Flick/",Filename,"TA.pdf",sep="")) qplot(fitted(profiles.spl), residuals(profiles.spl)) dev.off() ... -------------- John Helly, University of California, San Diego / San Diego Supercomputer Center / Scripps Institution of Oceanography / stonesteps (Skype) / stonesteps7 (iChat) / http://www.sdsc.edu/~hellyj [[alternative HTML version deleted]] ______________________________________________ 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.
