Hey, folk.
I am trying to get many figures by using the function "xyplot" in the library
"lattice". I tried to using the loop to finish it quickly. But I cannot open
the saved file after I run the program. But if I use the function "plot" to get
other simply figures, it can work. So I want to ask how I can get the saved
figures by using "xyplot".
The following is a simple example about my program:
library(lattice)
require(stats)
## Tonga Trench Earthquakes
Depth <- equal.count(quakes$depth, number=8, overlap=.1)
for (i in 1:5) {
filename=paste("fig",i,".pdf",sep="")
pdf(filename,width=6.5,height=4.5)
xyplot(lat ~ long | Depth, data = quakes)
graphics.off()
}
# I cannot open the pdf files.
Buf if I try:
for (i in 1:5) {
filename=paste("fig",i,".pdf",sep="")
pdf(filename,width=6.5,height=4.5)
plot(lat ~ long, data = quakes)
graphics.off()
}
# I can open the pdf files.
Hope you can help me.
Thanks so much,
