Plot Letter

Description

This function returns a plot of a single graph extracted from a document. It uses the letterList parameter from the processHandwriting() or processDocument() function and accepts a single value as whichLetter. Dims requires the dimensions of the entire document, since this isn’t contained in processHandwriting() or processDocument().

Usage

plotLetter(
  doc,
  whichLetter,
  showPaths = TRUE,
  showCentroid = TRUE,
  showSlope = TRUE,
  showNodes = TRUE
)

Arguments

doc	A document processed with processHandwriting() or processDocument()
whichLetter	Single value in 1:length(letterList) denoting which letter to plot.
showPaths	Whether the calculated paths on the letter should be shown with numbers.
showCentroid	Whether the centroid should be shown
showSlope	Whether the slope should be shown
showNodes	Whether the nodes should be shown

Value

Plot of single letter.

Examples

library(handwriter)

twoSent_document = list()
twoSent_document$image = twoSent
twoSent_document$thin = thinImage(twoSent_document$image)
twoSent_document$process = processHandwriting(twoSent_document$thin, dim(twoSent_document$image))
plotLetter(twoSent_document, 1)

plotLetter(twoSent_document, 4, showPaths = FALSE)
