The jamba package contains several jam base functions which are re-usable for routine R analysis work, and are important dependencies for other Jam R packages.
The goal will be to maintain these methods as lightweight as possible, so their inclusion in an analysis workflow will not incur a noticeable burden.
The sections and functions below are not comprehensive, but
provide examples of useful functions. The most highly-used functions
are: printDebug(), vigrep(), nameVector() with makeNames(),
pasteByRow(), showColors().
Enhanced graphics::smoothScatter() with plotSmoothScatter().
Enhanced graphics::image() with imageDefault()
for rasterized heatmaps that preserve aspect ratio for non-square
images; imageByColors() for data.frame of colors and optional
labels, which by default places unique labels centered within a block of
repeated values.
Quick color display showColors() for vector or list of color vectors.
Quick blank plot nullPlot() with optional labeling of margins.
Log-scaled axis labels minorLogTicksAxis().
Text labels using a border outline shadowText() for visible contrast.
Base plot wrappers getPlotAspect(), decideMfrow().
Alphanumeric sort with mixedSort(), mixedOrder(), mixedSortDF()
Custom wrappers to grep() for value-return vgrep(), vigrep();
case-insensitive pattern search igrep(), vigrep();
and grep with an ordered vector of patterns provigrep(), proigrep().
Name manipulations: make unique names with defined syntax
makeNames(); applying names to a vector nameVector();
named vector of names nameVectorN() useful with lapply().
Row-wise concatenation from data.frame or matrix pasteByRow()
optionally skipping blank values; list to matrix without filling
missing values rbindList().
Sorted base::table() with optional filter tcount().
Color interconversion functions designed to be reversible, e.g.
col2hcl() and col2hcl().
Set text contrast color for labels on colored background
setTextContrastColor().
Color wrapper functions makeColorDarker(), getColorRamp(),
showColors().
Colored text output printDebug(), colored R prompt setPrompt(),
vectorized text styling make_styles().
Interconversion from degrees to radians deg2rad(), rad2deg().
Simple date string functions getDate(), asDate(),
dateToDaysOld(), isDate(), fileInfo().
Padding character strings or integers with leading or trailing
values padString(), padInteger().
Removing or editing missing values in place: rmNA(),
rmNULL(), rmInfinite().
The jamba package recognizes some global options, but limits these
options to include only non-analysis options. For example, no global
option should change the numerical manipulation of data.
jam.lightMode - boolean, defines whether the text background
is light (TRUE is bright) or dark (FALSE is dark) mainly for the
purpose of restricting text output colors from printDebug so
they have visible contrast.
jam.adjustRgb - numerical setting used as a small adjustment of
colors used by the crayon functions to produce ANSI color text.
Other jam practical functions:
breakDensity(),
checkLightMode(),
