library(Rcatch22)

Rcatch22 is an R package for the calculation of 22 CAnonical Time-series CHaracteristics (catch). The package is an efficient implementation that calculates time-series features coded in C.

Core calculation function

The main function of the package is catch22_all which automates the computation of the 22 features. This can be run in a one-liner:

data <- rnorm(100)
outs <- catch22_all(data)

Taking a look at the returned dataframe, we can see a nice tidy data structure:

outs

catch24

An option to include the mean and standard deviation as features in addition to catch22 is available through setting the catch24 argument to TRUE:

outs2 <- catch22_all(data, catch24 = TRUE)
outs2

Feature list

A list of the time-series features included in Rcatch22 can be viewed using the included feature_list vector:
