graphics bug: type="l" (PR#120)
Tue, 16 Feb 1999 21:33:52 +0100

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.
