Twins Diabetes

A group of researchers studied the heights of youths diagnosed with type I diabetes. They wanted to see how diabetes affected height. The researchers compared identical twins, where one twin manifests the disease and the other twin does not. The researchers recorded the heights of the juveniles at the time one of them was diagnosed with type I diabetes.

Data details

There are 16 rows and 5 columns. The data source1 is used to create our data that is stored in our pins table. You can access this pin from a connection to posit.byui.edu using hathawayj/twins_diabetes.

This data is available to all.

Variable description

  • Twin: ID for each pair of twins
  • Age: Age at time of diagnosis (years)
  • Gender: Gender of twins (M, F)
  • NonDiabeticHeight: Height of non-diabetic twin (cm)
  • DiabeticHeight: Height of diabetic twin (cm)

URL Connections:

For public data, any user can connect and read the data using pins::board_connect_url() in R.

library(pins)
url_data <- "https://posit.byui.edu/data/twins_diabetes/"
board_url <- board_connect_url(c("dat" = url_data))
dat <- pin_read(board_url, "dat")

Use this custom function in Python to have the data in a Pandas DataFrame.

import pandas as pd
import requests
from io import BytesIO

def read_url_pin(name):
  url = "https://posit.byui.edu/data/" + name + "/" + name + ".parquet"
  response = requests.get(url)
  if response.status_code == 200:
    parquet_content = BytesIO(response.content)
    pandas_dataframe = pd.read_parquet(parquet_content)
    return pandas_dataframe
  else:
    print(f"Failed to retrieve data. Status code: {response.status_code}")
    return None

# Example usage:
pandas_df = read_url_pin("twins_diabetes")

Authenticated Connection:

Our connect server is https://posit.byui.edu which you assign to your CONNECT_SERVER environment variable. You must create an API key and store it in your environment under CONNECT_API_KEY.

Read more about environment variables and the pins package to understand how these environment variables are stored and accessed in R and Python with pins.
