Method for plotting the density of an RVG frequency table.

1 2 |

`x` |
object of class |

`rows` |
integer or array of integers that indicate the rows of the table for which the density is plotted. If missing all rows are used. |

`alpha` |
significance level for plotting critical values. |

`...` |
further graphical parameters. |

`plot`

creates a density plot for the given RVG frequency table.
The display zooms into the union of the range of frequency values and
2 times the confidence intervals for the frequencies.
Thus it visualizes significant deviations from the unifrom
distributions. The critical values for significance level `alpha`

are marked by a red (dashed) line.

`rows`

is either a number or a vector of numbers that indicate
the rows of RVG tabel `x`

which are merged (cumulated) for the
plot. If this argument is missing, all rows are merged.

`rvgt.ftable`

for creating the frequency table;
`hist`

for the height of the drawn rectangle.

## Create a frequency table for normal distribution and show histogram.
## Use a sample of size of 5 times 10^5 random variates.
ft <- rvgt.ftable(n=1e5,rep=5, rdist=rnorm,qdist=qnorm, mean=1,sd=2)
## Plot histogram
plot(ft)
## Plot histogram for row 1 only
plot(ft,rows=1)
## Plot histogram for rows 2 and 4 only
plot(ft,rows=c(2,4))
## Same with the buggy random variate generator
## (try to increase sample size 'n' or 'rep')
RNGkind(normal.kind="Buggy Kinderman-Ramage")
ft <- rvgt.ftable(n=1e5,rep=1, rdist=rnorm,qdist=qnorm)
plot(ft)
