Easily knit a custom figure fragment

THis function was written to make it easy to knit figures with different, or dynamically generated, widths and heights (and captions) in the same chunk when working with R Markdown.

knitFig(plotToDraw,
        template = getOption("ufs.knitFig.template", NULL),
        figWidth = getOption("ufs.knitFig.figWidth", 16/2.54),
        figHeight = getOption("ufs.knitFig.figHeight", 16/2.54),
        figCaption = "A plot.",
        chunkName = NULL, ...)

Arguments

plotToDraw	The plot to draw, e.g. a ggplot plot.
template	A character value with the knit_expand template to use.
figWidth	The width to set for the figure (in inches).
figHeight	The height to set for the figure (in inches).
figCaption	The caption to set for the figure.
chunkName	Optionally, the name for the chunk. To avoid problems because multiple chunks have the name "unnamed-chunk-1", if no chunk name is provided, digest is used to generate an MD5-hash from Sys.time.
…	Any additional arguments are passed on to knit_expand.

Value

This function returns nothing, but uses knit_expand and knit to cat the result.
