A method for creating vertical histograms sharing a y-axis using base graphics.

Add `freq`

argument which is equivalent to the `freq`

argument in `hist`

: if `FALSE`

(default), frequency densities are represented; if `TRUE`

, frequencies/counts are represented.

Add `rhs`

argument which, if specified, splits xyloplots in the middle, with left hand side distribution given by `x`

and right hand side by `rhs`

.

Added 'Examples' vignette and `xylo_positions`

function which lets you get the positions of the xylophones lest the user wants to add more graphical objects to the plot.

Fix bug whereby `max`

valued data point not shown for continuous data.

Added support for plotting discrete data supplied as character vectors or factors - e.g. `xyloplot(sample(c("goldfish","cat","dog","fish","mouse","giraffe"), size=100, replace=TRUE))`

, `xyloplot(replicate(n=5, simplify=FALSE, expr=factor(sample(c(0.01, 0.1, 0.2, 0.25, 0.5, 1), size=10, replace=TRUE))), col=rainbow(5))`
