date as dimension produced an error in case a
timestamp column with multiple classes had been used; fixed in this
release.timestamp as dimension produced an unnecessary
warning due to checks; this has been fixed.stringsAsFactors default configuration in
data.frame.The conversion to Date or POSIXct is
not forced anymore & depends on the initial class. This brings
significant speed to all functions (provided the initial class is
already date/timestamp);
There have been some other minor improvements in speed,
e.g. applying basic transformations to columns through
data.table’s set instead of
lapply and .SD.
The collapse_ranges function got two new arguments,
i.e. startAttr and endAttr - see
?collapse_ranges;
Moreover, the core function has been re-written in
Rcpp for some speed gains.
