ggDoE 0.7.8

BREAKING

  • gg_boxplots() arguments response,factor,group_var are now string characters

NEW FUNCTIONS

  • added theme_bw_nogrid(), simple theme settings which were used throughout ggDoE plots

CHANGES

  • removed dplyr dependency in favor of data.table. data.table has significantly less dependencies compared to dplyr.

  • added insightto Imports for checking if required packages are installed for each respective function. insight will later be used for cleaning up source code for extracting information from model objects such as variables, responses, etc...

  • switched gridExtra and unrepx from Imports to Suggests

MINOR CHANGES

  • updated pkgdown website with new theme and reference structure

ggDoE 0.7.7

BREAKING

  • renamed argument ncols to n_columns in all functions which previously used this argument. These functions are: diagnostic_plots(),gg_rsm(), interaction_effects(),main_effects(),twoD_projections()

NEW FEATURES

  • half_normal() has new argument point_color to change the color of the points
  • diagnostic_plots() has a new argument cooksD_type to change the threshold computed for Cook's distance plot (plot #6)

CHANGES

  • half_normal() now uses ggrepel::geom_text_repel instead of hard-coded geom_text to try and avoid label overlap

ggDoE 0.7.6

  • minor fixes to documentation/vignettes
  • moved unrepex from Suggests to Imports
  • added cran-comments.md

ggDoE 0.7.5

NEW FEATURES

  • changed appearance of gg_boxplots() from using fill to color. Added new argument jitter_points to gg_boxplots() to overlay points to boxplots.

  • Added initial vignette for a quick overview of ggDoE. Still needs further details for certain plots

ggDoE 0.7.4

BUX FIXES

  • Fixed bug in twoD_projections() that would output the same plot for every plot in the grid

ggDoE 0.7.3

NEW FUNCTIONS

  • Added new function twoD_projections(). This function will output all two dimensional projections from a Latin hypercube design. Will add further details to documentation in future updates.

CHANGES

  • Switched gridExtra to Imports instead of Suggests under Description file

ggDoE 0.7.2

CHANGES

  • Added new plot to visualize collinearity through variance inflation factor (VIF) in diagnostic_plots() function. This is the sixth diagnostic plot.

ggDoE 0.7.1

BREAKING

  • in gg_rsm() restricted model class to only be an rsm object. Future updates will add back lm class object option.

BUG FIXES

  • added error message to diagnostic_plots() to check if there is insufficient degrees of freedom to obtain standard errors, t.value. It won't plot any of the diagnostic plots for that model.

MINOR CHANGES

  • Consistent use of left-arrow operator (<-) for all functions in this package

ggDoE 0.7

  • Added a NEWS.md file to track changes to the package.

CURRENT FUNCTIONS

  • alias_matrix() Color Map on Correlations

  • boxcox_transform() Box-Cox transformation plot with 95% confidence interval of lambda values to consider

  • gg_boxplots() Boxplots created with ggplot2

  • diagnostic_plots() Regression Diagnostic Plots with ggplot2

  • gg_rsm() Contour plot(s) of a fitted linear model in ggplot2 from an RSM object

  • half_normal() A halfnormal plot for factorial effects

  • lambda_plot() Lambda plot for tracing t-staitics across different values of lambda

  • main_effects() Main effects plots for each factor in a design given a specified response

  • pareto_plot() A bar plot with ordered effects, margin of error (ME) and simultaneous margin of error (SME) cutoffs.

  • viridisPalette() A simple wrapper for the viridisLite package used for changing the color palette in most plots above
