cassowaryr 2.0.21

• Scree now adds a small jitter if data is perfectly colinear.
• Added second check for colinearity after outlier removal.
• all draw functions now have a set scale from [0,1] as that is scale the scagnostics are computed on (they are not rescaled after outlier removal).
• Added extra stringy tests back in

cassowaryr 2.0.20

• Moved hexbin to imports

cassowaryr 2.0.19

• Reverted default sc_skinny code to previous version.
• Updated all tests so they are able to run and pass with new changes.

cassowaryr 2.0.18

• Added diagnose_outliers function

cassowaryr 2.0.17

• Added vdiff tests for the draw_* functions

cassowaryr 2.0.16

• Depreciated sc_striated2 for sc_grid, sc_stringy for sc_stringy05, and sc_stringy2 for sc_stringy06

cassowaryr 2.0.15

• Updated the definition of sc_stringy05(), replacing the previous vertex-count-based calculation with the weighted MST diameter divided by the total MST edge length.

cassowaryr 2.0.14

• Renamed sc_stringy to sc_stringy06, corresponding to the 2006 version of the stringy index
• Renamed sc_stringy2 to sc_stringy05, corresponding to the 2005 version
• Updated documentation and ran full package checks
• Updated the vignette and fixed related errors
• Fixed several package errors and warnings

cassowaryr 2.0.13

• Skinny index fixed (including the straight-line error and unrealistically small values for visually skinny shapes).

cassowaryr 2.0.12

• standardised outlier removal in all functions to be out.rm parameter
• set binning and outlier removal to be default preprocessing steps across the entire package (including in the sc_* functions)
• included a propper description for each function that includes a citation to the definition
• consolidated the documentation for for the draw_* and top_* functions
• changed all the tidy pipes (%>%) to native pipes (|>)
• Changed the mst examples to be datasaurus dozen instead of anscomb due to small sample issues
• Change the default in all calc_scags functions to be the Wilkinson & wills scagnostics (rather than all the scagnostics in the package)
• Removed edge case versions of skinny and stringy (need to implement it in the scree)
• Rewrote clumpy using sapply (from for loops) and igraph functions so it is easier to read and runs faster

cassowaryr 2.0.11

• Broke scree function up so binning, outlier removal, and alpha calculations are in their own functions (and R files)
• Reverted outlier removal to old method, but made kept it iterative and in the scree
• Changed binning to the method implemented in the scanogstics R package
• Wrote tests for binning, outlier removal, alpha, and scree functions

cassowaryr 2.0.10

• Update draw functions so they accept a scree and also draw_alphahull allows you to set the alpha value
• Made the default alpha value clearer (alpha = "rahman")

cassowaryr 2.0.9

• Updated scree() so outlier_rm returns revised del, weights, and alpha.
• Added outlier_rm and binner options to all index functions and alpha option to alpha-hull–based indices.
• Added Tina’s name and ORCID to the package description.
• Modified sc_skinny and sc_stringy06 to return 1 for perfectly straight-line conditions.

cassowaryr 2.0.8

• Removed euclid parameter from calculation functions

cassowaryr 2.0.7

• Rename striated2 to grid and included epsilon parameter to control grid noise tolerance

cassowaryr 2.0.6

• Change alpha_omega to use mst_weights instead of weights (in the previous version I incorrectly used weights instead of mst_weights)
• Add iterative outlier removal in scree()

cassowaryr 2.0.5

• Changed Depends back to R (>= 4.0.0).
• Removed the Ubuntu oldrel R-CMD-check job from GitHub Actions, since it could not satisfy the previous R (>= 4.0.0) requirement or the new R (>= 4.5.0) dependency and was failing due to dependency errors.

cassowaryr 2.0.4

• Changed Depends to R (>= 4.5.0).
• Implemented hexagonal binning.
• Added hexbin package to Suggests (Description).

cassowaryr 2.0.3

• Added configurable alpha selection in scree(), with support for "rahman" (default), "q90", "omega", user-specified numeric values, and user-defined alpha functions.
• Temporarily skipped test_alphahull.R while alpha selection behaviour is being updated (issue).

cassowaryr 2.0.2 (2024-09-13)

• Updated the required version of interp to 1.1-6
• Changed the duplicate check inside the scree calculation to match the check done by interp

cassowaryr 2.0.1

• Added hex sticker
• Updated the required version of interp to 1.1-4

cassowaryr 2.0.0 (2022-08-09)

• In line with the alphahull 2.5 update, cassowaryr is now dependent on the package interp instead of tripack and which results in some issues to be addressed: -- scree() which calculates the convex and alpha hulls will return an error for any scatter plot where most of the data lies on a straight line -- scree() can take significantly longer on a select few scatter plots
• The energy package is now required instead of suggested
• The "line" subset in the features data is no longer a perfectly straight line to avoid the error above.

cassowaryr 1.0.1

• All functions now have a value description.
• The draw functions now have the option for outlier removal.
• draw_alphahull() function fill option now fills the polygon.

cassowaryr 1.0.0

• This package contains functions to compute scagnostics measuring different patterns in scatter plots.
