collapse 1.8.0

collapse 1.8.0, released mid of May 2022, brings enhanced support for indexed computations on time series and panel data by introducing flexible ‘indexed_frame’ and ‘indexed_series’ classes and surrounding infrastructure, sets a modest start to OpenMP multithreading as well as data transformation by reference in statistical functions, and enhances the packages descriptive statistics toolset.

collapse 1.7.0

collapse 1.7.0, released mid January 2022, brings major improvements in the computational backend of the package, its data manipulation capabilities, and a whole set of new functions that enable more flexible and memory efficient R programming - significantly enhancing the language itself. For the vast majority of codes, updating to 1.7 should not cause any problems.

collapse 1.6.5

collapse 1.6.4

Checks on the gcc11 compiler flagged an additional issue with a pointer pointing to element -1 of a C array (which I had done on purpose to index it with an R integer vector).

collapse 1.6.3

CRAN checks flagged a valgrind issue because of comparing an uninitialized value to something.

collapse 1.6.2

CRAN maintainers have asked me to remove a line in a Makevars file intended to reduce the size of Rcpp object files (which has been there since version 1.4). So the installed size of the package may now be larger.

collapse 1.6.1

A patch for 1.6.0 which fixes issues flagged by CRAN and adds a few handy extras.
