svycoplot: Conditioning plots of survey data In survey: Analysis of Complex Survey Samples

Description

Draws conditioned scatterplots ('Trellis' plots) of survey data using hexagonal binning or transparency.

Usage

 ```1 2``` ```svycoplot(formula, design, style = c("hexbin", "transparent"), basecol = "black", alpha = c(0, 0.8),hexscale=c("relative","absolute"), ...) ```

Arguments

 `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`

Value

An object of class `trellis`

Note

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.

`svyplot`

Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13``` ```data(api) dclus2<-svydesign(id=~dnum+snum, weights=~pw, data=apiclus2, fpc=~fpc1+fpc2) svycoplot(api00~api99|sch.wide*comp.imp, design=dclus2, style="hexbin") svycoplot(api00~api99|sch.wide*comp.imp, design=dclus2, style="hexbin", hexscale="absolute") svycoplot(api00~api99|sch.wide, design=dclus2, style="trans") svycoplot(api00~meals|stype,design=dclus2, style="transparent", basecol=function(d) c("darkred","purple","forestgreen")[as.numeric(d\$stype)], alpha=c(0,1)) ```
