# pdqr 0.3.0

- New function
`region_distance()`

computes distance
between pair of regions.
`summ_center()`

gets new method “midrange” with
corresponding new `summ_midrange()`

function. It returns a
mean of left and right edges of support.
`summ_distance()`

gets new method “avgdist”. It computes
average distance between sample values from inputs.
- New single-number option “pdqr.approx_discrete_n_grid” may be used
to tweak degree of granularity of how continuous pdqr-function is
approximated with discrete one during some complicated tasks (like in
`summ_distance()`

with method “avgdist”).

# pdqr 0.2.1

- Outputs of
`new_p()`

and `new_q()`

now work
more accurately in case of dirac-like functions.
`form_mix()`

now uses new algorithm of discontinuity
approximation, which enables proper handling of distributions with
“touching” supports.
- New boolean option “pdqr.assert_args” may be used to turn off sanity
checks of function arguments, which will somewhat increase general
execution speed.
- Minor fixes to remove CRAN “additional issues”.

# pdqr 0.2.0

`form_estimate()`

gets argument `estimate`

renamed to `stat`

to avoid possibly confusing word
duplication.
`form_retype()`

gets default value `NULL`

of
`type`

, which means taking opposite of input’s type. This
usage seems to be the most common.
`form_retype()`

gets new **default** method
“value” that preserves ratio of d-function values at certain “x” points.
It is more robust than previous options.
`summ_spread()`

gets new method “range” with
corresponding new `summ_range()`

function. It returns a range
length of “x” values within region of positive probability.
- New functions
`form_recenter()`

and
`form_respread()`

are implemented. They change center and
spread of distribution (with linear transformation) to be equal to some
desired value.
