quadrupen 0.2-8 (2020-11-18)

Minor: + Avoid warning in C++ to pass CRAN checks, thanks to a PR of Dirk Eddelbuettel [email protected] + Minors changes in examples, default mc.cores to 2

quadrupen 0.2-7 (2019-08-28)

Minor: + change sort(, 1) to sort(, "descend") in C++ code to avoid warnings during checks

quadrupen 0.2-6 (2018-04-30)

Minor: + change & to && in C++ code to avoid warnings during checks

quadrupen 0.2-5 (2017-03-07)

quadrupen 0.2-4 (2014-01-16)

Minor: + memory leak corrected (sp_mat declaration) + linking to Rcpp/RcppArmadillo headers (requires R 3.0-2)

quadrupen 0.2-3 (2013-09-30)

• added back the 'normalize' parameter
  • standardization is performed within the C++ code
  • use of sparse conversion from Matrix to Armadillo
  • corrected bug with the 'intercept' and 'residuals' components of the quadrupen class
  • added more tests in the inst directory
  • correction in the documentation
  • added r.squared to the quadrupen class

quadrupen 0.2-2 (2013-04-08)

• minor fix to comply with recent ggplot2 updates.

quadrupen 0.2-1 (2013-02-27)

• minor fix to pass CRAN check on Windows operating systems.

quadrupen 0.2-0 (2013-02-26)

Major: + added bounded regression (regression penalized by infinity norm + structered l2 norm) + added corresponding functionalies for cross-validation and stability path Minor: + corrected wrong annotations of the stability path (PFER) + handled normalization internally ('normalize' is no longer a parameter) + more simple internal handling of penscales and correction of the rescaling of the intercept + better use of multicore features + handled runtime error exception in RcppArmadillo when the system is singular (end of the solution path) A consequence is quadrupen is less likely to crash due to user's "bad" parametrization + simplification of the C++ code, bugs corrected, probably new ones added :-'( + added 'examples' and 'tests' directories

quadrupen 0.1-0 (2012-10-10)

• first build: structured elastic-net with (weighted) quadratic loss, cross-validation and stability selection methods.
