Download and Cache Medical Code CSV

Source: R/Medcode_download.R
download_medcode.Rd

Fetches a CSV file for the specified medical code from a remote server, caches it locally, and returns the path to the cached file.

Usage

download_medcode(name)

Arguments

name

A single character string specifying the code name (without ".csv"), e.g. "ICD10" or "CPT".

Value

A single character string giving the full path to the downloaded or previously cached CSV file.

Details

By default, when the package is loaded, .onLoad() sets options(RHealth.medcode_base) to "https://storage.googleapis.com/pyhealth/resource/". The CSV will be downloaded from file.path(getOption("RHealth.medcode_base"), paste0(name, ".csv")).

To override the download location, set your own base URL before calling:


options(RHealth.medcode_base = "https://your.server/medcode/")

Cached files are stored under: file.path(rappdirs::user_cache_dir("RHealth"), "medcode").

# Use default server
path1 <- download_medcode("ICD10")

# Use a custom server
options(RHealth.medcode_base = "https://internal.example.com/medcode/")
path2 <- download_medcode("CPT")
} # }
