svycoplot {survey} | R Documentation |
Draws conditioned scatterplots ('Trellis' plots) of survey data using hexagonal binning or transparency.
svycoplot(formula, design, style = c("hexbin", "transparent"), basecol = "black", alpha = c(0, 0.8),hexscale=c("relative","absolute"), ...)
formula |
A graph formula suitable for xyplot |
design |
A survey design object |
style |
Hexagonal binning or transparent color? |
basecol |
The fully opaque 'base' color for creating transparent
colors. This may also be a function; see svyplot for details |
alpha |
Minimum and maximum opacity |
hexscale |
Scale hexagons separate for each panel (relative) or across all panels (absolute) |
... |
Other arguments passed to grid.hexagons or xyplot |
An object of class trellis
As with all 'Trellis' graphs, this function creates an object but does
not draw the graph. When used inside a function or non-interactively
you need to print()
the result to create the graph.
