Improvements to greedy methods

This release improved some efficiency limitations of the greedy design methods. The methods are much more efficient now.

cbcTools 0.5.0

In v0.5.0 of the package, further revisions were made to the method argument in the cbc_design() function. The "random" and "dopt" methods were added, and restrictions were added so that orthogonal designs cannot use the label argument or restricted profile sets (as either of these would result in a non-orthogonal design). A table was also added in the documentation clarifying the different options supported by each design method.

cbcTools 0.4.0

This release marks v0.4.0 of the package. The main change was updating how the method argument works in cbc_design(), along with the introduction of a new method for orthogonal designs, pulling on the DoE.base package. This function is now better set up to add in new methods in the future.

cbcTools 0.3.0

This release addresses the following issues: #7 , #9, #10

For #7, I modified code in cbc_design() to avoid duplicate choice sets for the same respondents in random designs.

For #9 and #10, I modified code in cbc_design() to allow Bayesian D-efficient designs with restricted profile sets. I also added some input checks to make sure that the program would stop or throw warnings appropriately if the input settings made it impossible to create a design.

cbcTools 0.2.0

This is the first release of {cbcTools} to CRAN.
