hello list! I'm sorry, I just stumbled over this strange behaviour (at
least I am not able to explain the behaviour, therefore I assume it to
be a strange behaviour):
attach(water) # I know, this is not recommended
names(water[3:10])
[1] "temp" "pH" "DO" "BOD" "COD" "no3" "no2" "po4"
for (i in names(water)[3:10]){
fname<-paste("Henni/GFX/fem",i,".png",sep="")
mname<-paste("Henni/GFX/mal",i,".png",sep="")
png(fname,1000,1000)
xyplot(N_female~eval(parse(text=i)) |group,xlab=i,ylab="Abundance")
graphics.off()
png(mname,1000,1000)
xyplot(N_male~eval(parse(text=i)) |group,xlab=i,ylab="Abundance")
graphics.off()
}
well, to anyone's surprise, there are no plots in the folder. the loop
finishes (i, fname and mname have values assigned) and executing
png(fname,1000,1000)
xyplot(N_female~eval(parse(text=i)) |group,xlab=i,ylab="Abundance")
graphics.off()
does produce a png in the folder. I assume this to be caused by the png
function, since removing the graphics.off() and playing with dev.off()
and the likes did not help. anyone ideas?? am I missing the obvious??
