What I'm wondering is what EXACTLY are C, D, E

问题 I've tried self.lblTimer = [[UILabel alloc] initWithFrame:CGRectMake(x,y,width,height)]; ..but since the label i'm looking to position is at the bottom of the screen it goes out of view when i switch devices.

I tried using something like: somevar <- 1 jpg(paste(sep='',filename,'.%03d.jpg')) while(somevar <= n) { plot(data[somevar]) dev.new() somevar <- somevar + 1 } dev.off() but it creates one .jpg file and several Rplotnnn.pdf files.
