Log message:
(math/R-classInt) Update 0.4.8 to 0.4.9, make test passed

## Version 0.4-9

- #41 issues. The maximum and minimum breaks are set to \code{+Inf}
   and \code{-Inf} to avoid errors induced in the earlier version
   where breaks could cease to be strictly ascending. The
   \code{legacy=} argument with value \code{TRUE} may be used to
   revert to the previous behaviour.

(math/R-classInt) Updated 0.4.3 to 0.4.8

## Version 0.4-8

- #18 and #38: `classIntervals()` has a new style `"box"`, where a box
   map is an augmented quartile map, with an additional lower and
   upper category. When there are lower outliers, then the starting
   point for the breaks is the minimum value, and the second break is
   the lower fence. When there are no lower outliers, then the
   starting point for the breaks will be the lower fence, and the
   second break is the minimum value (there will be no observations
   that fall in the interval between the lower fence and the minimum
   value) (@angela-li, @dieghernan).

## Version 0.4-7

- A new helper function `classify_intervals()` is introduced to return
  a vector of class intervals of same length as input (@JosiahParry)

- `classIntervals()` has a new style `"maximum"` which returns maximum
  breaks classification based on the pysal library
  [mapclassify](https://pysal.org/mapclassify/index.html)
  (@JosiahParry)

- `findCols()` now takes new argument `factor` which, when `TRUE`
  returns class membership as a factor with intervals as labels

Log message:
(math/R-classInt) Add compiler.mk buildlink

Without this change, I have following error with 9.99.82 host (amd64) which
has gcc-10. And buildlink for libgfortran was only made for gcc-10 side.
Adding this line makes both gcc-7 and gcc-10 buildlinked.

The error I had was: ( the line folded)

Log message:
(math/R-classInt) Updated  0.4.2 to 0.4.3, ChangeLog not updated (?)

Log message:
R-classInt: update to 0.4.2.

Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the
following:

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.
