visualizationQualityControl 0.5.3

  • median_correlations now has more columns, regardless of the setting for between_classes, to provide consistency.
  • median_correlations output gains an extra column, group to allow easier filtering of within and between class comparisons.

visualizationQualityControl 0.5.2

  • Fixed behavior of visqc_test_pca_scores to skip testing attributes that either have a single value, or the number of numeric values matches the number of samples.

visualizationQualityControl 0.5.0

  • Changed some functions to treat columns as samples and rows as features:

    • keep_non_zero_percentage
    • summarize_data
    • calculate_fratio

  • Added keep_non_missing_percentage, which allows using multiple values to represent missingnes.

  • Made summarize_data handle possible missing values.

  • Removed correlation calculation functions, those have been superseded by ICIKendallTau.

visualizationQualityControl 0.4.11

  • Added a new argument only_high to determine_outliers to only look at the high end of the score distribution for outliers, as sometimes boxplot.stats will pick up outliers at the low end as well.

visualizationQualityControl 0.4.10

  • Updated the quality_control vignette to use ICIKendallTau instead of other correlation measures.

visualizationQualityControl 0.4.9

  • Windows and Mac binaries are now available via r-universe, and installation instructions are updated to reflect that.

visualizationQualityControl 0.4.7

  • Updated determine_outliers to be able to use either the output from median_correlations or outlier_fraction singly or together. If using one or the other alone, I suggest explicitly naming the arguments so that the correct entry is set to NULL and the other one used.
  • Updated the README to show using ici_kendalltau instead of the it_weighted_correlation.
  • Updated tests, and moved to testthat v 3.
  • Updated pkgdown for rendering the help site.

visualizationQualityControl 0.4.0

  • Moving all of the ICI-Kendall-tau code into it's own package, ICIKendallTau. This reduces the dependencies necessary if all you want is to run a fast Kendall-tau.

visualizationQualityControl 0.3.100

  • Making the splitup version of ICI-Kendall-tau the "implementation" (visqc_ici_kendallt), and using a single core if the user doesn't setup a "plan" first. A reference version still exists so we can run tests against it, but it is no longer exported for general users.

  • Also inlined the C++ sign function, which gave us another 3X speedup on my 8 core machine on a larger test data set.

visualizationQualityControl 0.3.96

  • Now throw an error if X and Y are not the same length in ici_kendallt.

visualizationQualityControl 0.3.85

  • Added a function for calculating the information-content-informed Kendall-tau correlation, ici_kendallt, and variants around calculating all pairwise correlations between samples; visqc_ici_kendallt and visqc_ici_kendallt_splitup for parallel processing.

visualizationQualityControl 0.3.16

  • Removed requirement for ggbiplot, instead we added a function for calculating the variances of each of the PCs in the scores.

  • updated the vignette accordingly.

  • Now using globally_it_weighted_correlation and locally_it_weighted_correlation instead of pairwise_correlation.

visualizationQualityControl 0.3.2

  • keep_non_zero_percentage gains an argument, all, that defaults to FALSE to keep previous behavior. Setting all = TRUE means that the value must be non-zero in at least X% of all of the sample classes.

visualizationQualityControl 0.3.0

  • median_correlations gains a new argument, between_classes to generate the median values to samples in other classes. This causes the appearance of two more columns when set to TRUE. The default is FALSE, so hopefully this does not cause current code to misbehave, but I've bumped the version number as a warning.

visualizationQualityControl 0.2.18

  • Augmented correlations (weight = TRUE) should be much more useful and interpretable.

  • information_volume and correspondence calculations improved. Namely that information_volume is being scaled by the maximum.

  • correspondence by default does not consider presence of zeros in both samples to be informative, this can be changed by setting not_both = TRUE. The default is more useful in cases where there are lots of features and the data is sparse, and zeros are likely to happen by chance.

  • In addition to returning the cor matrix and keep matrix, pairwise_correlations now returns the raw correlations, and the weighting matrices info and correspondence so that each one can be examined.

  • The diagonal of info weighting corresponds to how many features a sample has compared to the sample with the most features.

visualizationQualityControl 0.2.5

  • Added two functions, information_volume and correspondence to calculate weights based on the amount of things that are non-zero in both things when doing pairwise correlation.

  • Added logical argument weight to pairwise_correlation to weight the correlations. If weight = TRUE, the diagonal will not be 1 anymore, but instead will reflect how many features out of the total are in that sample.

visualizationQualityControl 0.2.3

  • A bug was discovered in median_correlations that meant the wrong sample ids might be added to the output data, making detection of real problems difficult

visualizationQualityControl 0.2.1

  • pairwise_correlation now uses cor internally directly, whereas previously it did a for loop to allow pairwise comparisons. This makes the correlations 3x faster.

  • count has been removed from the list returned by pairwise_correlation

  • new function pairwise_correlation_count to get the counts in each pairwise comparison

visualizationQualityControl 0.1.1

  • Changed correlation function to return a list instead of a matrix. This list contains the correlations (cor), counts in each correlation (count), and which points passed the criteria (keep).
