Plot polls

Draws the individual polls as points and every trend added with popAddTrend() (or already published by POLITICO) as a line. Trends that come with a variance, such as kalman, are drawn with an uncertainty band, the events in x$events as vertical lines.

Usage

# S3 method for class 'popPolls'
plot(x, ..., bands = TRUE, level = 0.95, events = TRUE)

Arguments

x

A popPolls object.

...

Passed on to graphics::plot(), e.g. xlim to limit the date range. xlim takes dates or ISO date strings, NA keeps the respective end of the data range. The y axis is scaled to the polls inside xlim.

bands

Whether uncertainty bands should be drawn.

level

Coverage of the uncertainty bands.

events

Whether events should be marked.

Value

Invisibly x.

Examples

if (FALSE) { # \dontrun{
de = popRead('DE-parliament')
de = popAddTrend(de, name = 'kalman', type = 'kalman')
plot(de)
plot(de, xlim = c('2024-01-01', NA), level = 0.9)
} # }
