[R] plot.hclust point to older version

[William Dunlap]

You probably have a local copy of an old version of plot.hclust or
plot.dendrogram in your global environmenet or another package that masks
the one in package:stats.  E.g., I fired up R-2.14.2 and copied those 2
plot methods to .GlobalEnv and then saved by workspace when quitting R.  I
then fired up R-3.1.1, which loads the workspace saved by the older version
of R.  I get:

> objects()
[1] "plot.dendrogram" "plot.hclust"
> plot(hclust(dist(c(2,3,5,7,11,13,17,19))))
Error in .Internal(dend.window(n, merge, height, hang, labels, ...)) :
  there is no .Internal function 'dend.window'
> traceback()
2: plot.hclust(hclust(dist(c(2, 3, 5, 7, 11, 13, 17, 19))))
1: plot(hclust(dist(c(2, 3, 5, 7, 11, 13, 17, 19))))

Note how calling traceback() after an error gives more information about
the source of the error.

To fix this, get rid of the .RData file that is being loaded when R starts.
