Description General Utility Text Manipulation Plotting 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.

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.

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.

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.
