R Project Updates

Updates from R Core:

• The self starting function attr(SSlogis, "initial") now also works when the y values have exact minimum zero and is slightly changed in general, behaving symmetrically in the y range.

• When tar() is used with an external command which is detected to be GNU tar or libarchive tar (aka bsdtar), a different command-line is generated to circumvent line-length limits in the shell.

• system(*, intern=F), file.edit() and file.show() now issue a warning when the external command cannot be executed.

• .C when returning a logical vector now maps values other than FALSE and NA to TRUE, as documented.

• system, file.show, and file.edit now even on Windows report an error when external command cannot be executed.

• range(c(TRUE,NA), finite=TRUE) and similar no longer return NA. (Reported by Lukas Stadler.)
