animation-defunct: Defunct functions in the animation package.
Description
Defunct functions in the animation package.Details
highlight.def is irrelevant to animations and hence it is no longer
in this package; the source code was moved to
http://yihui.name/en/2007/09/r-language-definition-file-for-highlight/.
write.rss is irrelevant either; the source code can be found at
https://github.com/yihui/animation/raw/1650902e43fe283d4fd0cea8f559e4e5187d60fe/R/write.rss.R.
tidy.source has been moved to the formatR package.
ani.news is no longer necessary since R has got a function
news in the utils package
