If the title string to a histogram is of length > 1, the words 'Histogram of'
get pasted to each element. Looks wrong.



Produces a title that goes:

  Histogram of apply(matrix(0,10,10),1,function(x){
          Histogram of runif(1)
             Histogram of })

Its in the way that 'Histogram of' is pasted to the deparsed expression. If that
expression has an anonymous function in it, then that gets deparsed into a
vector of length 3, and hence 'Histogram of' gets put on the start of each one.

There's probably several trivial ways to fix this, so I wont choose one, but
leave it to the experts.
