musicMCT 0.2.0

New ineqmat features

• New make_black_ineqmat() and make_gray_ineqmat() allow new transposition-sensitive hyperplane arrangements to be studied; ineqmat parameter for other functions (e.g.  signvector() now accepts “black” and “gray” as options.
• New make_offset_ineqmat() creates version of standard ineqmats (MCT, white, black, etc.) which have been translated to be centered on an arbitrary set.
• Creation functions for ineqmats (makeineqmat(), make_black_ineqmat(), make_white_ineqmat(), make_roth_ineqmat()) now return a consistent value (integer(0)) rather than various errors when card is small.
• New data set roth_ineqmats.rda with precomputed results from make_roth_ineqmat(); accessed with new get_roth_ineqmat().
• New data sets for pastel and white arrangements (for cardinalities <= 6) uploaded to modalcolortheory repository and linked in the documentation for make_white_ineqmat().

New behaviors for quantization functions

• Affected functions are quantize_color(), quantize_hue(), and set_from_signvector().
• Upon failure, quantization functions now return a result whose format matches expected success format depending on value of reconvert parameter. That is, if reconvert=TRUE, failure to quantize results in a NA vector (as before), but if reconvert=FALSE, failure to quantize results in a list with entries set and edo, both of which are NA.
• Quantization functions gain a target_edo parameter, which allows user to search for desired scales in a specific edo rather than all possible edos.

New Functions

• New clockface() offers a simple plotting mechanism to visualize sets on a pitch-class clockface (with numbers corresponding to any equal temperament).
• New ianring() creates a convenient way to open a browser window to information about the input set on Ian Ring’s website The Exciting Universe of Music Theory.
• New functions for basic applications of the DFT to set theory are added. These include set_to_distribution(), distribution_to_set(), and dft().

Updates to Existing Functions

• brightnessgraph() now returns an invisible copy of the igraph graph object underlying the plotted brightness graph, instead of an invisible NULL.
• sim() gains a goal parameter, which allows it to calculate the interscalar interval matrix for two sets.
• vl_generators() now throws a warning instead of an error when set is perfectly even, returning a 2-by-0 matrix.

musicMCT 0.1.2

• Updated writeSCL() to require user to enter a path.
• Updated vignette “Visualizing Higher Dimensions” to reset par() changes.

musicMCT 0.1.1

• Removed extraneous license file.

musicMCT 0.1.0

• Initial CRAN submission.
