[R] for loop for automatic pdf generation

[stephen sefick]

Sorry for not reading the FAQ- that solved the problem.


#loop to spit out PDFs
list.names <- as.character(unique(braggxsec[,"Creek"]))
pdf("~/Desktop/base_pdf_xsec/braggxsec.pdf")
for(i in 1:length(list.names)){
f <- 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())
print(f)
}
dev.off()

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
