R Project Updates

Updates from R Core.

  • (Windows only) Tcl/Tk version 8.6.4 is now included in the binary builds. The tcltk*.chm help file is no longer included; please use URL: instead.

  • Illegal factors, e.g., with duplicated levels (illegal but constructable) now give a warning when printed, via new .valid.factor.

  • str(<looooooooong_string>) is no longer very slow; inspired by Mikko Korpela’s proposal in PR#16527.

  • After seven years of deprecation, duplicated factor levels now produce an error in levels<- instead of a warning, and a warning when printed.

  • New option rstandard(<lm>, type = "predicted") provides the “PRESS”-related leave-one-out cross-validation errors for linear models.

  • addNA() is faster now, e.g., when applied twice PR#16895.

Quote of the Week

R – the ultimate virus

R changed my opinion of humanity to some extent, to see how people are really willing to freely give of themselves and produce something larger than themselves without any thought of personal glory.

An NA is the presence of an absence. Don’t forget that some missing values are the absence of a presence #rstats
