R Project Updates

Updates from R Core.

• xtabs(~ exclude) no longer fails from wrong scope.

• str(x)’s default method is more “accurate” and hence somewhat more generous in displaying character vectors; this will occasionally change R outputs (and need changes to some *.Rout(.save) files). For a classed integer vector such as x <- xtabs(~ c(1,9,9,9)), str(x) now shows both the class and "int", instead of only the latter.

• Changes in R 3.3.2

Upcoming Events

• rstudio::conf 2017 January 13 and 14, 2017
  The conference about all things R and RStudio.
