df2mat

Convert a 3-column data.frame (dim1, dim2, value) to a 2-D matrix

internal

A 'ggplot2'-consistent approach to generating 2D displays of  volumetric brain imaging data.
Display data from multiple NIfTI images using standard 'ggplot2' conventions such scales, limits, and
themes to control the appearance of displays. The resulting plots are returned as 'patchwork' objects,
inheriting from 'ggplot', allowing for any standard modifications of display aesthetics supported by 'ggplot2'.

df2mat function

<dl><dt>df</dt>
<dd>A <code>data.frame</code> representing a melted 2-D matrix, having columns dim1, dim2, and value</dd>
<dt>replace_na</dt>
<dd>if not <code>NULL</code>, this numeric value will be used to replace any NAs in <code>df</code> in the
resulting matrix. This is useful if downstream code is not built to handle missing values.</dd></dl>
