I don't know if anyone is reading this, but I have more information now. I can run the same script on my other computer over and over, change the height, width and res, and it works every time. But on the faulty computer, I can open R, open the script, and run it and it works. I can re-run it any number of times and it works. However, when I change the height, width, or res settings in the function, I get the error message. From that point on, even if I change the height, width, or res back to what worked before, it will no longer run and I get the error message. I can only get it to run again by shutting down the program, re-opening R and the script, and running it again. This is just bizarre to me and I have no idea why I am having this problem. Thanks if you are still reading, and I welcome any input. I'm not very technically savvy, but I am running it on Windows XP Pro Version 2002, Service Pack 3.
The following works for me:
> png("test.png", width=50000, height=50000, res=1000)
Error in png("test.png", width = 50000, height = 50000, res = 1000) :
unable to start png() device
In addition: Warning messages:
1: In png("test.png", width = 50000, height = 50000, res = 1000) :
Unable to allocate bitmap
2: In png("test.png", width = 50000, height = 50000, res = 1000) :
opening device failed
> png("test.png",width=1000, height=1000, res=1200)
> dev.off()
