moderndive 0.5.3

• Added alaska_flights consisting of Alaska Airlines subset of nycflights13::flights

moderndive 0.5.2

• Changed printing of non-baseline categorical variable levels in regression table to be cleaner #102
• Added explicit conf.level argument to get_regression_table() inherited from broom::tidy.lm()
• Improved main package vignette based on feedback from @lwjohnst86 & @lisamr
• Added JOSE publication in vignettes/paper.md
• Fixed pkgdown and covr issues, defragged documentation.

moderndive 0.5.1

• Use vdiffr conditionally

moderndive 0.5.0

• Modified vignettes/why-moderndive.Rmd main vignette
• Updated geom_parallel_slopes() with new arguments:
  • Use fullrange=TRUE to draw regression lines over the entire support of the x-axis (by @wjhopper)
  • Use level to set different level of confidence interval shading (by @echasnovski)
• Added new function geom_categorical_model() for visualizing regression models with one categorical explanatory/predictor variable (by @wjhopper)
• Add deprecation warning message to gg_parallel_slopes() directing users to use geom_parallel_slopes() instead (by @mariumtapal)

moderndive 0.4.0

• Added geom_parallel_slopes() geom extension to ggplot2 package to plot parallel slopes regression models with one numerical and one categorical variable (this is not possible using ggplot2::geom_smooth()). Note this renders gg_parallel_slopes() function added in v0.3.0 obsolete.
• Added example of geom_parallel_slopes() to “Why moderndive?” vignette
• Added student names (permission obtained in all cases) to pennies_resamples data frame columns
• get_correlation() now:
  • Respects dplyr::group_by() grouping
  • Can handle missing data by either passing na.rm = TRUE argument or by passing standard stats:cor(use = "complete.obs") argument via ...

moderndive 0.3.0

• Added minimally viable “parallel slopes” regression model plotting function gg_parallel_slopes(). In the future we hope to define a new ggplot2 geom.
• Added “Why moderndive?” vignette
• Added ID argument to get_regression_points() to return a column that identifies the observational units/rows
• Datasets:
  • Added DD_vs_SB: Dunkin Donuts and Starbucks in Eastern Massachusetts data collected by @DelaneyMoran
  • Added promotions: tibble version of openintro::gender.discrimination used to illustrate permutation test.
  • Added MA_schools: Relationship between SAT scores and socio-economic status for Massachusetts high schools.
  • Added mythbusters_yawn: Data from study on Mythbusters show on whether yawning is
  • Added promotions_shuffled: one instance of promotions with gender permuted/shuffled
  • Original pennies_sample sample of 40 pennies from pennies has been renamed orig_pennies_sample. New pennies_sample consists of 50 pennies sampled from bank in Northampton, MA, USA on 2019/2/1.
  • Added pennies_resamples: 35 bootstrap resamples of new pennies_sample
  • Added movies_genre: random sample of 32 action and 36 romance movies from ggplot2movies::movies
    
• Removed all assertive::assert() code
• Converted house_prices$date from dttm (date-time) to date per R4DS comment on using simplest data type possible

moderndive 0.2.0

Updated package for:

• Use in DataCamp’s Modeling with Data in the Tidyverse, in particular added evals and house_prices datasets and updated get_regression_table() and get_regression_points() functions.
• v0.4.0 of ModernDive textbook

Details:

• Created get_correlation() function to omit $ syntax and return a data frame
• Import infer::rep_sample_n() instead of our own defined version, as this function is now included in infer
• Added evals, house_prices, tactile_prop_red, pennies_sample and mythbusters_yawn datasets
• Added mean squared error and root mean squared error to output of get_regression_summaries()
• Added newdata argument to get_regression_points(). When:
  • Original outcome variable is included in newdata, output it as well as residual (See Issue 17).
  • Otherwise omit residual
• Removed tidyverse from Depends, Imports, or Suggests

moderndive 0.1.1

Fixed broken url in ?bowl_samples

moderndive 0.1.0

• Added three get_regression_* functions meant for novice R users/regression fitters that process regression model outputs
• Added datasets:
  • pennies: 800 pennies to be treated as a population from which to simulate sampling a numerical variable from (year of minting)
  • bowl: Bowl of 2400 balls of which 900 are red to be treated as a population from which to simulate sampling a categorical variable from (color). Also known as the urn sampling framework .
  • bowl_samples: data from tactile version of sampling from bowl done in class: 10 groups sampled n=50 balls from and counted the number red [ADD MODERNDIVE LINK]
