When possible, use more numerically stable implementations #10

Closed twolodzko closed 6 years ago

twolodzko commented 6 years ago

Issues like #9 can happen also in other cases, more numerically stable implementations need to be used.

The accompanying tests can be found in tests/testthat/test-pure-r-benchmarks.R that compare the "naive" R implementations with numerically stable implementations in C++.
