Hi Dr Sklyar,
This is interesting to know - I have just noticed that it also happens every 100 points, there is another disjoint between 200 and 201. I have attached a file showing this. The file was created using the following code: > png("disjoint2.png") > plot(1:210, type="l") > dev.off() Regards, Richard 2008/6/27 Sklyar, Oleg (MI London) <osklyar@...>: > I do not see any disjoint on 2.7.0 patched (r45879) or 2.8.0 devel > (r45830) on RHEL5 64bit. > > Dr Oleg Sklyar > Technology Group > Man Investments Ltd > +44 (0)20 7144 3803 > osklyar@... > >> -----Original Message----- >> From: r-devel-bounces@... >> [mailto:r-devel-bounces@...] On Behalf Of Richard Martin >> Sent: 27 June 2008 12:38 >> To: r-devel@... >> Subject: [Rd] plot(type="l") disjoint between 100 and 101st datapoint >> >> Dear All: >> >> We have been experiencing networking issues so I don't know >> if this got through; I can't see it in the archive.
