Documentation

On this Picostat.com statistics page, you will find information about the urine data set which pertains to Urine Analysis Data. The urine data set is found in the boot R package. You can load the urine data set in R by issuing the following command at the console data("urine"). This will load the data into a variable called urine. If R says the urine data set is not found, you can try installing the package by issuing this command install.packages("boot") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the urine R data set. The size of this file is about 2,439 bytes.


Urine Analysis Data

Description

The urine data frame has 79 rows and 7 columns.

79 urine specimens were analyzed in an effort to determine if certain physical characteristics of the urine might be related to the formation of calcium oxalate crystals.

Usage

urine

Format

This data frame contains the following columns:

r

Indicator of the presence of calcium oxalate crystals.

gravity

The specific gravity of the urine.

ph

The pH reading of the urine.

osmo

The osmolarity of the urine. Osmolarity is proportional to the concentration of molecules in solution.

cond

The conductivity of the urine. Conductivity is proportional to the concentration of charged ions in solution.

urea

The urea concentration in millimoles per litre.

calc

The calcium concentration in millimoles per litre.
