[R] gap.plot fails to plot tick labels on y-axis

[Jim Lemon]

Hi Ludo,
The good news is that it was easy. The bad news is that it was my fault. I
hadn't tried labeling the axes with something other than numbers. At about
line 109 in the source code, this line:

    show.labels<-c(ytics[littletics],yticlab[bigtics])

should read:

    show.labels<-c(yticlab[littletics],yticlab[bigtics])

Attached is the code that you can "source" after loading plotrix and the
fix will be in the next version. Thanks.

Jim
