deformGrid2d

visualise differences between two superimposed sets of 2D landmarks

Description

visualise differences between two superimposed sets of 2D landmarks by deforming a square grid based on a thin-plate spline interpolation

Usage

deformGrid2d(matrix, tarmatrix, ngrid = 0, lwd = 1, show = c(1:2),
  lines = TRUE, lcol = 1, col1 = 2, col2 = 3, pcaxis = FALSE,
  add = FALSE, wireframe = NULL, margin = 0.2, gridcol = "grey",
  cex1 = 1, cex2 = 1, ...)

Arguments

`matrix`	reference matrix containing 2D landmark coordinates or mesh of class "mesh3d"
`tarmatrix`	target matrix containing 2D landmark coordinates or mesh of class "mesh3d"
`ngrid`	number of grid lines to be plotted; ngrid=0 suppresses grid creation.
`lwd`	width of lines connecting landmarks.
`show`	integer (vector): if c(1:2) both configs will be plotted, show = 1 only plots the reference and show = 2 the target. plotted. Options are combinations of 1,2 and 3.
`lines`	logical: if TRUE, lines between landmarks will be plotted.
`lcol`	color of lines
`col1`	color of "matrix"
`col2`	color of "tarmat"
`pcaxis`	logical: align grid by shape's principal axes.
`add`	logical: if TRUE, output will be drawn on existing plot.
`wireframe`	list/vector containing row indices to be plotted as wireframe (see `lineplot`.)
`margin`	margin around the bounding box to draw the grid
`gridcol`	color of the grid
`cex1`	control size of points belonging to `matrix`
`cex2`	control size of points belonging to `tarmatrix`
`...`	additional parameters passed to plot
