I have a 2 by 226200 table, conveniently read in by read.table(), which exhibits some strange behavior when plotted by plot(V1,V2). The general pattern for the range of windspeeds, [0<V1<50] is as expected -- the wind gust falls in the interval [V1<V2<65] except for certain values of V2. For V2 == c(15,26,37,48,59), the V2 values are positioned at one-tenth of the V1 (i.e., as if I had issued the command plot(0.1*V1,V2) for just those values of V2 -- see attached plot, test.png). The only other values of V2 in the range, 4 and 70, also seem to be affected but aren't well enough represented to show up clearly on the plot.
However, if I plot(ws$V1[ws$V2==48],ws$V2[ws$V2==48]), I see the second attachment, test2.png, which confirms that the wind speed (V1) really should be positioned where one would expect. I haven't seen any messages covering this behaviour and so am looking for an explanation.
