A data frame with 22 observations on the following 4 variables.
GHQ
the General Health Questionnaire score.
sex
a factor with levels female and male
cases
the number of diseased subjects.
non.cases
the number of healthy subjects.
Details
The data arise from a study of a psychiatric screening questionnaire
called the GHQ (General Health Questionnaire, see Goldberg, 1972).
Here the main question of interest is to see how caseness is related to
gender and GHQ score.

Examples
data("GHQ", package = "HSAUR")
male <- subset(GHQ, sex == "male")
female <- subset(GHQ, sex == "female")
layout(matrix(1:2, ncol = 2))
barplot(t(as.matrix(male[,c("cases", "non.cases")])), main = "Male", xlab = "GHC score")
barplot(t(as.matrix(male[,c("cases", "non.cases")])), main = "Female", xlab = "GHC score")
