tsqqplot: Quantile-Quantile Plots
Description
`tsqqplot` is a function to produce a normal QQ plot of the values in y.
Usage
tsqqplot(
x,
title = NULL,
x.name = NULL,
qq.pwidth = 0.7,
qq.lwidth = 0.7,
qq.col = "black",
qqline.col = "red"
)
Value
A QQ plot of x will be displayed with no further values or objects returned.
Arguments
- x
a univariate time series object or a numeric vector or matrix.
- title
title of the QQ plot. Default is NULL.
- x.name
name of the series. If omitted here, the series name found by tsname() will be taken over here. If tsname() is NULL, the variable name will be used instead. Default is NULL.
- qq.pwidth
size of the markers in the QQ plot. Default is 0.7.
- qq.lwidth
line width of the theoretical normal line in the QQ plot. Default is 0.7.
- qq.col
colour of the data points in the QQ plot. Default is `black`.
- qqline.col
colour of the theoretical normal line in the QQ plot. Default is `red`.
