R Dataset / Package MASS / Rabbit

On this R-data statistics page, you will find information about the Rabbit data set which pertains to Blood Pressure in Rabbits. The Rabbit data set is found in the MASS R package. You can load the Rabbit data set in R by issuing the following command at the console data("Rabbit"). This will load the data into a variable called Rabbit. If R says the Rabbit data set is not found, you can try installing the package by issuing this command install.packages("MASS") and then attempt to reload the data with the library() command. 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 Rabbit R data set. The size of this file is about 1,554 bytes.

Blood Pressure in Rabbits

Description

Five rabbits were studied on two occasions, after treatment with saline (control) and after treatment with the 5-HT_3 antagonist MDL 72222. After each treatment ascending doses of phenylbiguanide were injected intravenously at 10 minute intervals and the responses of mean blood pressure measured. The goal was to test whether the cardiogenic chemoreflex elicited by phenylbiguanide depends on the activation of 5-HT_3 receptors.

Usage

Rabbit

Format
