PEFR: Peak Expiratory Flow Rate (PEFR) measurements with Wright peak flow and mini Wright peak flow meter.

Description

Measurement of PEFR with Wright peak flow and mini Wright peak flow meter on 17 individuals.

Format

A data frame with 68 observations on the following 3 variables.

meth

a factor with levels Wright and Mini, representing measurements by a Wright peak flow meter and a mini Wright meter respectively, in random order.

item

Numeric vector, the person ID.

y

Numeric vector, the measurements, i.e. PEFR for the two measurements with a Wright peak flow meter and a mini Wright meter respectively. The measurement unit is l/min.

repl

Numeric vector, replicate number. Replicates are exchangeable within item.

Examples

PEFR <- Meth(PEFR)
summary(PEFR)
