Urine Analysis Data

Description:

The urine data frame has 77 rows and 9 columns.

77 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.

Variables:

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.
