EddingtonModule {eddington}

An Rcpp Module for Tracking Eddington Numbers for Cycling

Description

A stateful C++ object for computing Eddington numbers.

Arguments

rides

An optional vector of values used to initialize the class.

store_cumulative

Whether to store a vector of the cumulative Eddington number, as accessed from the cumulative property.

Fields

new

Constructor. Parameter list may either be empty, store_cumulative, or rides and store_cumulative

current

The current Eddington number.

cumulative

A vector of Eddington numbers or NULL if store_cumulative is FALSE.

hashmap

A data.frame containing the distances and counts above the current Eddington number.

update

Update the class state with new data.

getNumberToNext

Get the number of additional distances required to reach the next Eddington number.

getNumberToTarget

Get the number of additional distances required to reach a target Eddington number.

Warning

EddingtonModule objects cannot be serialized at this time; they cannot be carried between sessions using base::saveRDS or base::save and then loaded later using base::readRDS or base::load.

Examples

# Create a class instance with some initial data
e <- EddingtonModule$new(c(3, 3, 2), store_cumulative = TRUE)
e$current

# Update with new data and look at the vector of cumulative Eddington numbers.
e$update(c(3, 3, 5))
e$cumulative

# Get the number of rides required to reach the next Eddington number and
# an Eddington number of 4.
e$getNumberToNext()
e$getNumberToTarget(4)
