graphics bug: type="l" (PR#120)
mcw@ln.nimh.nih.gov writes:
The following commands illustrate a problem with graphing relatively large data sets using the "line" option to plot: temp <- runif(200000) # or whatever other numbers you like; # same thing happens with a sine wave plot(1:200000, temp) # everything fine plot(1:200000, temp, type="l") # data gets cut off The number of points isn't crucial. The cutoff point appears to be about 65,000 points. (70,000 points demonstrates the cutoff; with 50,000 points there's no cutoff.) As far as I can tell, the problem only occurs when using the option type="l". It's unaffected by color, line type, and line width. Matt Wiener
Doesn't happen to me with 0.63.pre-3 on RedHat Linux. I can't offhand see any documented fixes that would affect this, perhaps there's an OS difference? Looks a bit like a short integer overrun (65536=2^16)
