microRutils: Mike Rowe's Miscellaneous R Utility Functions

The microRutils package contains various functions for text manipulation, plotting and general utility. These have been developed over the last decade or so; they range from the picayune to the highly useful.

Version: 1.0.3.20210610

General Utility:

• cbindSafe(), rbindSafe(): Column-/row-wise concatenation of objects with potentially different rows/columns.
• compressMatrix(): Resize a matrix by combining adjacent elements.
• express(): Programmatically generate expression objects.
• getLapplyIndex(): Access index of list element from within lapply().
• nameslike(): Find named elements, rows or columns using a regular expression.
• nonUniq(): Find replicated elements in a vector.
• numberReplicates(): Number recurring elements within a vector.
• Order(): Order items using columns of a data.frame as keys.
• prepDir(): Create a new directory.
• pvalOrder(): Order p-values by levels, then numeric value.
• rowMads(): Fast calculation of MADs by row.
• rowSds(): Fast calculation of standard deviations of rows.
• rowZs(): Fast calculation of Z-scores by row.
• samediff(): Find elements in common, and unique to, two vectors.
• selectRows(): Row selection of a data.frame.
• uniqRowFreqs(): Count occurrences of replicate rows in a data.frame.
• untab(): Convert a table object to an array.

Text Manipulation:

• is.char(), as.char(): Alises for as.character() and is.character().
• asciiToChar(): Conversion between letters and ASCII codes.
• cString(): Create a c() expression from character vector.
• orString(): Generate an OR regular expression substring.
• p.print(): Formats p-values for readability.
• percent(): Format numeric values as (character) percentages.
• regextr(): Substring extraction by regular expression.
• rename(): Rename elements, rows or columns, etc. of an object.
• strrev(): Reverse character order within each element of a character vector.
• yyyymmdd(): Generate a formatted time stamp.

Plotting Functions:

• circle(): Plot a circle or regular polygon.
• Custom colormaps for heat maps: aqua.brown(), grayscale, hot(), hot2(), jet(), orange.blue(), purple.green(), purple.orange(), red.green(), yellow.blue()
• enclose.plot(): Draw edge around a plot.
• groupedTickLabels(): Label axes with hierarchically organized groups.
• Hist(): Modified version of the graphics::hist() histogram function.
• Image(): Modified version of the graphics::image() plotting function.
• logtix(): Add log-scaled tick marks to an axis.
• plot2Dhist(): Generate and plot a 2D-histogram as a heatmap.
• sym(): Get a numeric range that is symmetric around zero.
• T.width(): Determine width of caps on error bars as fraction of plot width.
• VennPlot(): Draw a Venn plot with proportional areas.
• x.pt(), y.pt(): Get the location value associated with a fraction of x- or y-axis.
