This blog is updated daily.
A general description is here.
‘R CMD INSTALL’ and hence ‘install.packages()’ gave an internal error installing a package called ‘description’ from a tarball on a case-insensitive file system.
‘match(x, t)’ (and hence ‘x %in% t’) failed when ‘x’ was of length one, and either ‘character’ and ‘x’ and ‘t’ only differed in their ‘Encoding’ or when ‘x’ and ‘t’ where ‘complex’ with ‘NA’s or ‘NaN’s. (PR#16885.)
‘unloadNamespace(ns)’ also works again when ‘ns’ is a ‘namespace’, as from ‘getNamespace()’.
‘rgamma(1,Inf)’ or ‘rgamma(1, 0,0)’ no longer give ‘NaN’ but the correct limit.
‘length(baseenv())’ is correct now.
‘pretty(d, ..)’ for date-time ‘d’ rarely failed when ‘"halfmonth"’ time steps were tried (PR#16923) and on ‘inaccurate’ platforms such as 32-bit windows or a configuration with ‘--disable-long-double’; see comment #15 of PR#16761.
In ‘text.default(x, y, labels)’, the rarely(?) used default for ‘labels’ is now correct also for the case of a 2-column matrix ‘x’ and missing ‘y’.
‘as.factor(c(a = 1L))’ preserves ‘names()’ again as in R < 3.1.0.
‘strtrim(""[0], 0[0])’ now works.
Use of ‘Ctrl-C’ to terminate a reverse incremental search started by ‘Ctrl-R’ in the ‘readline’-based Unix terminal interface is now supported for ‘readline’ >= 6.3 (‘Ctrl-G’ always worked). (PR#16603)
‘diff(<difftime>)’ now keeps the ‘"units"’ attribute, as subtraction already did, PR#16940.
