In inspectdf: Inspection, Comparison and Visualisation of Data Frames

inspectdf 0.0.11

• Bug fixes to inspect_types() for pairwise comparison plots
• Updated tests for inspect_types() for pairwise comparisons
• Migrate to vdiffr 1.0.0 for graphics tests
• Fixed #32, improved appearance of inspect_cat() plots when number of categories is small. Thanks to Ivo Kwee for the suggestion.
• Fixed #40, ensuring inspect_num() histogram bins are correct in comparisons of data frames. Thanks to Roel Verbelen for the report.

inspectdf 0.0.10

• Add include_int option in inspect_cat() to allow treatment of integer columns as categorical.
• Improved p-values associated with binned categorical and numeric comparisons. This is now based on a modified chi-squared test and is labelled as pval in the resulting output.
• Fixed #27 ensuring plots for inspect_cat() respect any filtering or sorting of the summary output prior to show_plot(). Thanks to Roel Verbelen for the report.
• Additional detail in inspect_type() comparison of two dataframes to make it easier to see which columns and types differ.

inspectdf 0.0.9

• Minor change, ensuring all functions use return properly.

inspectdf 0.0.8

• Important change: the show_plot argument has been removed from all inspect_*() functions. To generate visualisations of data frame summaries, please use the more flexible show_plot(inspect_*()) or via the pipe inspect_*() %>% show_plot().
• show_plot() improvement that nudges points that might otherwise have coincided for dataframe comparisons of imbalance (for example, with inspect_imb(df1, df2) %>% show_plot())
• Plots for grouped summaries: inspect_cor(), inspect_na() and `inspect.
• inspect_cor() slight speed up for dataframes with large numbers of columns.
• inspect_cor() can be filtered prior to plotting, for example inspect_cor(starwars) %>% filter(abs(corr) > 0.2) %>% show_plot(). Thanks to Roel Verbelen for the suggestion
• Fixed bug causing inspect_imb() to fail on certain types of factor columns. Thanks to Roel Verbelen for the report.
• show_plot() has new arguments label_size, label_angle and label_color. Each provide adjustments to text annotation where applicable. Thanks to Bartosz Bursa for the suggestion.
• changes to text annotation to improve how coord_flip() works on resulting plots. Thanks to Roel Verbelen for the report.

inspectdf 0.0.7

• Added bytes column to inspect_mem() output, for downstream numeric comparison and consistency with inspectpd.
• Added pcnt_nna column to inspect_cor() output containing the percentage of pairwise complete observations used calculated correlations. Thanks to Theo Broekman for the suggestion.
• Fixed bug causing order of grouping variable in grouped inspect_ statements to be incorrect. Thanks to the report from Theo Broekman.
• Removed erroneous print statement from inspect_num().

inspectdf 0.0.6

• Updates to documentation throughout.
• inspect_* functions now returns results by group grouped dataframes.
• Added option for inspect_num() %>% show_plot() to show histograms with color palettes specified by the col_palette argument.
• Fixed bug causing inspect_imb() to sometimes fail when factors present. Thanks to Doug Friedman for the report.

inspectdf 0.0.5

• Fixed error causing inspect_num() to fail when columns contained all NA values. Thanks to Ryan Tanner for the report
• Speed-up of inspect_cor() for large data frames with many numeric columns.
• Added approximate confidence intervals and tests for method = 'kendall' and method = 'spearman' in inspect_cor().

inspectdf 0.0.4

• Fix issue causing inspect_na() %>% show_plot() to fail when 0 NA present. Thanks to the report by Metin Yazici.
• show_plot() now returns a ggplot2 object rather than printing the plot - thanks to Garrick Aden-Buie for the suggestion.
• Dramatic speed up of inspect_cat plotting by avoiding text labels for small regions.
• Added tech dataset.
• Fix for text annotation of inspect_cat() plots when labels are empty strings. By default "" will be shown. Thanks to Michael Swenson for the report
• inspect_cor(method = ...) argument added, thanks to suggestion from George Dontas. Options for pearson, spearman and kendall. Note that confidence intervals and tests currently only supported for pearson.
• Fix error when duplicate factor labels present in inspect_cat() & inspect_imb().

inspectdf 0.0.3

• text_labels autoscale size using ggfittext::geom_fit_text(). For an example see inspect_cat(). Thanks to David Wilkins for the PR.
• 6 different color palettes supported in show_plot() via col_palette argument. Colorblind friendly option specified via show_plot(col_palette = 1) - thanks to Richard Careaga for the suggestion.
• inspect_imb().
  • include_na option for categorical columns that are 100% missing, or constant are underlined in plot for easier comprehension.
• inspect_cor()
  • Points and whiskers changed to coloured bands for single dataframe summaries - these are easier to see when CIs are narrow.
  • Points changed to bars for inspect_cor() comparison plots - makes it easier to see smaller differences in correlations.
  • NA correlations omitted from inspect_cor() comparison when plotted. Ordering of correlations reversed to be consistent with returned tibble.

inspectdf 0.0.2

• show_plot() function (show_plot argument in inspect_ functions will be dropped in a future version)
• high_cardinality argument in show_plot() for combining unique or near-unique categories for plotting inspect_cat().
• progress bars shown when processing larger datasets
• Improvements to plots throughout

inspectdf 0.0.1

• Initial CRAN release
