aidR is an open-source R package for reading and standardizing data exported from automated insulin delivery (AID) systems.

AID platforms differ in their file formats, variable names, units, timestamp conventions, and representation of clinically relevant events. aidR maps these heterogeneous exports to a common, analysis-ready format, allowing downstream analyses to be written once and applied consistently across AID systems.

What can aidR do?

aidR provides a common workflow for AID data:

Read native exports from seven major diabetes management platforms
Standardize CGM, basal, bolus, carbohydrate, and SMBG data
Filter CGM and carbohydrate data
Check data completeness and insulin totals
Visualize daily glucose, insulin, carbohydrate, and SMBG data
Merge data across participants and AID systems
Convert data to DIAX and formats used by iglu and cgmquantify

Overview of the aidR workflow

Supported export formats

aidR currently supports seven export formats:

Platform	Export format	Example AID systems
Glooko	Folder with one CSV per data type	CamAPS FX, Omnipod
CareLink (Medtronic)	Single `.xlsx` or `.csv` export	MiniMed 780G
mylife Cloud (Ypsomed)	Single semicolon-delimited CSV	CamAPS FX
Tidepool	Multi-sheet `.xlsx` workbook	Tandem Control-IQ, Loop, AAPS
YourLoops (Diabeloop)	Folder with one CSV per data type	DBLG1, DBLG2
Tandem Source	Folder with one CSV per data type	Tandem Control-IQ
Dexcom Clarity	Single delimited CSV (CGM only)	Any AID system using a Dexcom sensor

Installation

Install aidR directly from CRAN:

install.packages("aidR")

or get the latest version from github:

pak::pak("madleina/aidR")

Then load the package:

library(aidR)

Quick start

The main entry point is parse_data(), which reads a subject’s AID export and standardizes the major data types into a common format.

library(aidR)

data <- parse_data(
  id = "1",
  paths = "inst/extdata/glooko_example.zip"
)

names(data)
#> [1] "cgm"         "basal"       "bolus"       "SMBG"
#> [5] "carbs"       "total_basal" "total_bolus"

Visualizing AID data

plot_day() provides a daily overview of glucose, insulin delivery, carbohydrate entries, and SMBG measurements.

Contributing

Contributions are welcome. In particular, we welcome support for new AID platforms and updates to existing parsers when export formats change.

Please use the GitHub issue tracker for bugs and feature requests.

[!IMPORTANT] When reporting parsing problems, do not upload identifiable patient data to a public GitHub issue.
