data(gforces)A data frame containing 8 observations with the following 3 variables.
Subjectthe initials of the subject; a text identifier
Agethe age of the subject, in years; a numeric vector
Signswhether the subject showed syncopal blackout-related signs:
a factor with levels 0 (No) and 1 (Yes)
Military pilots sometimes black out when their brains are deprived of oxygen due to G-forces during violent manoeuvres. Glaister and Miller (1990) produced similar symptoms by exposing volunteers' lower bodies to negative air pressure, likewise decreasing oxygen to the brain. The data lists the subjects' ages and whether they showed syncopal blackout related signs (pallor, sweating, slow heartbeat, unconsciousness) during an 18 minute period.
