- CHANGES IN R 3.5.2:
PACKAGE INSTALLATION:
* New macro CXX_VISIBILITY analogous to C_VISIBILITY (which several
packages have been misusing for C++ code) for the default C++
compiler (but not necessarily one used for non-default C++
dialects like C++14).
TESTING:
* The random number generator tests in tests/p-r-random-tests.R no
longer fail occasionally as they now randomly sample from
"certified" random seeds.
BUG FIXES:
* The "glm" method of drop1() miscalculated the score test
(test="Rao") when the model contained an offset.
* Linear multiple empty models such as lm(y ~ 0) now have a
correctly dimensioned empty coefficient matrix; reported by Brett
Presnell.
* vcov() and hence confint() now work (via a consistency
change in summary.lm()).
* confint() now works correctly; reported on R-devel
by Steven Pav.
* quade.test() now also works correctly when its arguments are not
yet sorted along groups, fixing PR#15842.
* Installation on a Unix-alike tries harder to link to the pthread
library where required (rather than relying on OpenMP to provide
it: configuring with --disable-openmp was failing on some Linux
systems).
* The data.frame method for print(x) is fast now also for large
data frames x and got an optional argument max, thanks to
suggestions by Juan Telleria.
* hist() no longer integer overflows in very rare cases, fixing
