On this R-data statistics page, you will find information about the respiratory data set which pertains to Respiratory Illness Data . The respiratory data set is found in the HSAUR R package. You can load the respiratory data set in R by issuing the following command at the console data("respiratory"). This will load the data into a variable called respiratory. If R says the respiratory data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") 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 respiratory R data set. The size of this file is about 9,759 bytes.
Respiratory Illness Data
The respiratory status of patients recruited for a randomised clinical multicenter trial.
A data frame with 555 observations on the following 7 variables.
the study center, a factor with levels
the treatment arm, a factor with levels
a factor with levels
the age of the patient.
the respiratory status (response variable), a factor with levels
the month, each patient was examined at months
the patient ID, a factor with levels
In each of two centres, eligible patients were randomly assigned to active treatment or placebo. During the treatment, the respiratory status (categorised
good) was determined at each of four, monthly visits. The trial recruited 111 participants (54 in the active group, 57 in the placebo group) and there were no missing data for either the responses or the covariates. The question of interest is to assess whether the treatment is effective and to estimate its effect.
Note that the data are in long form, i.e, repeated measurments are stored as additional rows in the data frame.
