Convenience S3 methods for working with ggcpt objects: coerce the
changepoints to a tibble or data frame, render a one-line summary string, or
produce the default plot (a base-graphics fallback that delegates to
autoplot.ggcpt).
Usage
# S3 method for class 'ggcpt'
as_tibble(x, ..., .name_repair = NULL)
# S3 method for class 'ggcpt'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)
# S3 method for class 'ggcpt'
format(x, ...)
# S3 method for class 'ggcpt'
plot(x, ...)Arguments
- x
A
ggcptobject.- ...
Additional arguments passed to methods.
- .name_repair
Ignored (the changepoints tibble already has valid, unique names); present for signature compatibility with the generic.
- row.names, optional
Passed to
as.data.frame.
Value
as_tibble() and as.data.frame() return the changepoints
table; format() returns a length-one character string; plot()
returns a ggplot object.
Examples
set.seed(2022)
res <- cpt_detect(c(rnorm(50), rnorm(50, 5)), method = "pelt")
as_tibble(res)
#> # A tibble: 1 × 2
#> cp cp_value
#> <int> <dbl>
#> 1 50 0.368
as.data.frame(res)
#> cp cp_value
#> 1 50 0.3681734
format(res)
#> [1] "ggcpt [pelt] 1 changepoint(s) on 100 observations"
