CHANGES IN R VERSION 2.3.0
USER-VISIBLE CHANGES
o In the grid package there are new ‘arrow’ arguments to
grid.line.to(), grid.lines(), and grid.segments()
(grid.arrows() has been deprecated).The new ‘arrow’ arguments have been added BEFORE
the ‘name’, ‘gp’ and ‘vp’ arguments so existing code that
specifies any of these arguments *by position* (not by name)
will fail.o all.equal() is more stringent, see the PR#8191 bug fix below.
o The data frame argument to transform() is no longer called ‘x’,
but ‘_data’. Since this is an invalid name, it is less likely
to clash with names given to transformed variables. (People
were getting into trouble with transform(data, x=y+z).)
