plot.cv_poisson_rt: Plot cv_poisson_rt

In rtestim: Estimate the Effective Reproductive Number with Trend Filtering

Plot cv_poisson_rt

Description

Plot cv_poisson_rt

Usage

## S3 method for class 'cv_poisson_rt'
plot(x, which_lambda = c("cv_scores", "lambda.min", "lambda.1se"), ...)

Arguments

x	result of cv_estimate_rt of class cv_poisson_rt
which_lambda	select which Rt's to plot. If not provided, the cross validation score will be plotted. If provided a list of lambda, the corresponding Rt estimation will be plotted. If provided a string, it must be either one of lambda.min, lambda.1se, or cv_scores. If provided lambda.min, plot Rt which is generated from the lambda that minimizes the cross validation score. If provided lambda.1se, plot Rt which is generated from the lambda whose corresponding cross validation score is 1 standard error away of the minimal cross validation score. If provided cv_scores, plot the cross validation score. If NULL, all estimated Rt values are plotted.
...	Not used.

Value

a ggplot2::ggplot

Examples

y <- c(1, rpois(100, dnorm(1:100, 50, 15) * 500 + 1))
cv <- cv_estimate_rt(y, korder = 1, nfold = 3, nsol = 30)
plot(cv)
plot(cv, which_lambda = cv$lambda[1])
plot(cv, which_lambda = "lambda.min")
plot(cv, which_lambda = "lambda.1se")
plot(cv, NULL)
