animation 2.7

• saveGIF() didn't work when the option ani.dev is set to a function (thanks, @stla, #120 #121).

• The ani.res option works for saveHTML() and saveVideo() now (thanks, @trevorld, #127 #129).

• The ani.res option works for arbitrary graphical devices now (thanks, @trevorld, #135).

animation 2.6

• Added a new option ani.res to ani.options(), to control the resolution of png, jpeg, bmp and tiff images when using saveGIF() (#99).

• saveGIF() and im.convert() now support converting using the 'magick' R package which does not require shelling out to external software.

• The stopping criterion in kmeans.ani() was buggy: the iteration should stop only when the cluster centers do not change any more (thanks, Sen Zhou).

animation 2.5

• removed all examples from the package, since this package failed to pass R CMD check on CRAN for unknown reasons; all examples are still available on Github https://github.com/yihui/animation/tree/master/inst/examples and they will be moved to https://yihui.name/animation in the future
