In patchPlot: Scatterplots of image patches

Description Usage Arguments Value Author(s) See Also Examples

Draw a scatterplot with images patches as placeholders for the points.

1	drawPatches(data, patches, patchSize=0.05, alpha=0.5, patchNpix=20, highlight=numeric(0), labels=rep("1", length(highlight)))

`data`	nx2 matrix of points positions in the 2D space.
`patches`	rgbpatch object, with n rows in each channel specifying n elements. The values of a row-element are mapped to pixel intensities. Patch width is deduced from patchNpix argument.
`patchSize`	patch size as a ratio of the whole window.
`alpha`	If highlight is empty, this is the alpha value for all patches. Else if a set is highlighted, highlighted elements have this alpha value, and other elements have alpha/20.
`patchNpix`	expected size of the image patches sides. Should match the specification of patches object.
`highlight`	numeric vector taking values in 1..n, indicating elements in data to highlight. Patches are associated to alpha=1 if highlighted, 0.04 if not. If no highlight is specified, all patches have alpha=1.
`labels`	text labels associated to highlighted elements. Defauts to "1" for all highlighted elements.
