Memoize Function with Split Context — memoize_with

Creates a memoized version of a function that includes split_id in the cache key. This is the recommended way to add caching to custom functions.

Usage

memoize_with_split(f, cache = NULL)

Arguments

f: Function to memoize
cache: Cache object (optional, creates new if NULL)

Value

A memoized function that requires split_id as first argument

Details

The returned function has signature: function(split_id, ...) The split_id is used in the cache key but passed through to f.

Examples

if (FALSE) { # \dontrun{
# Original function
expensive_computation <- function(data, param) {
  # ... expensive operation ...
}

# Memoized version
cached_computation <- memoize_with_split(expensive_computation)

# Usage in CV loop
for (i in 1:5) {
  split_id <- paste0("fold_", i)
  result <- cached_computation(split_id, data = fold_data, param = 0.5)
}
} # }
