Hello Peter,
Thank you, and the R core team, for the new release.


I see that in R 2.11.0 there is now support for rendering of raster (bitmap)
images through rasterImage().

I am wondering - can this be used to create a texture/fill-pattern for
hist()/barplot()  ?
(A request made several times throughout the years on the mailing list.
For example:
http://osdir.com/ml/lang.r.general/2005-07/msg00799.html
)

(I am also sending this e-mail to the maintainers of lattice, ggplot2 and
gplots in the hope for more perspectives)

With much respect,
Tal

>    o   Trying to dispatch S4 methods for primitives during the search
>        for inherited methods slows that search down and potentially
>        could cause an infinite recursion.  An internal switch was
>        added to turn off all such methods from

>    o   R framework installation (on Mac OS X) would not work properly
>        if a rogue Resources directory was present at the top level.
>        Such a non-symlink will now be renamed to Resources.old (and

>    o   The checks for conforming S4 method arguments could fail when
>        the signature of the generic function omitted some of the

>        should now be ignored (treated as "ANY") in dispatching.
>
>    o   The computations for S4 method evaluation when '...' was in the
>        signature could fail, treating '...' as an ordinary symbol.
>        This has been fixed, for the known cases.

>    o   callNextMethod now works again with the drop= argument in `[`
>
>    o   parse() and parse_Rd() miscounted columns when multibyte UTF-8

>
>    o   Formatting of help pages has had minor improvements: extra
>        blank lines have been removed from the text format, and empty
>        package labels removed from HTML.
>
>    o   cor(A, B) where A has n x 1 and B a 1-dimensional array
>        segfaulted or gave an internal error.

>    o   cut.POSIXt() applied to a start value after the DST transition
>        on a DST-change day could give the wrong time for 'breaks' in units

>    o   Internal function matchArgs no longer modifies the general

>    o   gsub() in 2.10.x could fail from stack overflow for extremely

>
>    o   The internal C function 'coerceSymbol' now handles coercion to

>    o   The X11() device with cairo but not Pango (notably Mac OS X)

>    o   All the results from hist() now use the nominal 'breaks' not
