Barplots and Dotplots

Description

Draws a barplot or dotplot based on results from a survey analysis. The default barplot method already works for results from svytable.

Usage

## S3 method for class 'svystat'
barplot(height, ...)
## S3 method for class 'svrepstat'
barplot(height, ...)
## S3 method for class 'svyby'
barplot(height,beside=TRUE, ...)

## S3 method for class 'svystat'
dotchart(x,...,pch=19)
## S3 method for class 'svrepstat'
dotchart(x,...,pch=19)
## S3 method for class 'svyby'
dotchart(x,...,pch=19)

Arguments

`height,x`	Analysis result
`beside`	Grouped, rather than stacked, bars
`...`	Arguments to `barplot` or `dotchart`
`pch`	Overrides the default in `dotchart.default`

Examples

data(api)
dclus1<-svydesign(id=~dnum, weights=~pw, data=apiclus1, fpc=~fpc)

a<-svymean(~stype, dclus1)
barplot(a)
barplot(a, names.arg=c("Elementary","High","Middle"), col="purple", 
  main="Proportions of school level")

b<-svyby(~enroll+api.stu, ~stype, dclus1, svymean)
barplot(b,beside=TRUE,legend=TRUE)
