R Project Updates

Updates from R Core:

• file("stdin") is no longer considered seekable.

• dput() and dump() are no longer truncating when options(deparse.max.lines = *) is set.

• Calls with an S3 class are no longer evaluated when printed, fixing part of PR#17398, thanks to a patch from Lionel Henry.

• lengths() dispatches internally to S4 methods.

• predict(fm, newdata) is now correct also for models where the formula has terms such as splines::ns(..) or stats::poly(..), fixing PR#17414, based on a patch from Duncan Murdoch.

• extendrange(.., f) with a length-2 f now extends separately to the left and the right.

Quotes of the Week

I have a confession to make: Last year in July, I went cold turkey with #rstats to force myself to get really good at #Python. Today I fell off the wagon. What can I say? R is beautiful. It's beautiful, it's beautiful, I missed R so much.

I just likened the use of `<<-` to “blood magic” and I think the analogy basically works. #rstats
