A general description is here.
‘smooth(x, *)’ now also works for long vectors.
‘smooth(*, do.ends=TRUE)’ did not always work correctly in R versions between 3.0.0 and 3.2.3.
‘pretty(D)’ for date-time objects ‘D’ now also works well if ‘range(D)’ is (much) smaller than a second. In the case of only one unique value in ‘D’, the pretty range now is more symmetric around that value than previously.
The figures in help pages such as ‘?points’ were accidentally damaged, and did not appear in R 3.2.3. (PR#16708)
