On this R-data statistics page, you will find information about the GHQ data set which pertains to General Health Questionnaire . The GHQ data set is found in the HSAUR R package. You can load the GHQ data set in R by issuing the following command at the console data("GHQ"). This will load the data into a variable called GHQ. If R says the GHQ 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 GHQ R data set. The size of this file is about 347 bytes.

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")
