profmem 0.6.0 (2020-12-13)

The defaults of arguments 'expr' and 'newpage' of print() for Rprofmem can now be set via options 'profmem.print.expr' and 'profmem.print.newpage'.

The 'bytes' column returned by readRprofmem() would be of type integer when zero allocation events where read, whereas otherwise it would be of type numeric.
print(x) for Rprofmem now uses an explicit stringsAsFactors=FALSE when internally coercing 'x' to a data frame.

Nested profmem() calls are now supported, such that inner profmem() calls will not affect outer ones. This allows, for instance, a package to use profmem internally without having to worry about profmem already being active when its functions are called.

Added profmem_begin() and profmem_end() as an alternative to profmem().
Added profmem_suspend() and profmem_resume() for suspending and resuming an active profmem session.
Added profmem_status() for checking whether profmem is inactive, active, or suspended.
Added profmem_depth() to get the current depth of nested profmem sessions.
print() for Rprofmem now reports on the threshold used, if known.
print() for Rprofmem gained arguments 'expr = TRUE' and 'newpage = FALSE', controlling whether the profiled R expression and 'new page' entries should be displayed or not.
Added option 'profmem.threshold' for controlling the default threshold level for profmem() and profmem_begin().

VIGNETTE: Updated the example in Section 'An example where memory profiling can make a difference' due to improvements in R (>= 3.4.0), which made the previous example no longer valid.
help("profmem") how provide much more details previously only available in the vignette.
