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.
