[R] for loop for automatic pdf generation

[stephen sefick]

I know this is not reproducible, but I don't want to clog up mail
boxes with the data frame.  I would be happy to send this off list.  I
am sure that I am missing something simple. The plotting works if I
just paste the call to qplot into R and replace the [i] with a number.
  Thanks for all of your help in advance.


#loop to spit out PDFs
list.names <- as.character(unique(braggxsec[,"Creek"]))
for(i in 1:length(list.names)){
	pdf(paste("~/Desktop/base_pdf_xsec/", list.names[i], ".pdf", sep=""))
	qplot(measurment_num, value , data=subset(braggxsec.melt,
Creek==list.names[i]), colour=variable, geom="line", xlab="meters
across the channel", ylab="meters from bankfull", col="black",
linetype=variable,
main=list.names[i])+facet_grid(station~Creek)+scale_y_reverse(breaks=breaks)+scale_x_reverse()+theme_bw()+
opts(panel.grid.minor = theme_blank(), panel.grid.major=theme_blank())
	dev.off()
}
