barplot.svystat {survey} | R Documentation

## 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)
    dotchart(b)
