Hello,
While running the following code I encountered a bit of a funny error.
First the code:
library(animation)
ani.options(convert = shQuote('C:/Program
Files/ImageMagick-6.7.0-Q16/convert.exe'))
plot.ani<-function() {
for (ts in 1:730){
dat<-read.table(paste("c:/temp/ConcProfile_",ts,".txt",sep=""),
header=T,sep='\t')
#tiff(paste("c:/temp/Plot_ConcProfile_sp",ts,".tif",sep=""),height=800,width=600,res=130)
plot(dat$Conc[1:200],rev(dat$Depth[1:200]),type="l",xlab="Conc.",ylab="Depth",
yaxt="n",col="blue",lwd=2,xlim=c(0,120))
axis(side=2,at=seq(0,200,by=25),labels=rev(seq(0,200,by=25)),las=1)
axis(side=2,at=seq(0,200,by=5),labels=F,tcl=-0.25)
text(x=110,y=200,paste("SP ",ts,sep=""))
ani.pause()
#dev.off()
}
}
saveMovie(plot.ani(),movie.name="concSlug.gif",img.name="ConcProfile",interval=0.15,outdir=getwd())

# There seems to be an error in the conversion...
The code runs without issue when I dump individual tiff images to the temp
directory (that is, I run only the for loop). Is there a limit to the
number of frames that can be added? If I shorten the for loop to 100 the
gif is created, if I try to run it all the way out to 730 days (as coded
above) it terminates with the rather non-descriptive error above. Is there
an option I've overlooked?
Thanks...
Eric
