R Dataset / Package DAAG / head.injury


On this R-data statistics page, you will find information about the head.injury data set which pertains to Minor Head Injury (Simulated) Data. The head.injury data set is found in the DAAG R package. You can load the head.injury data set in R by issuing the following command at the console data("head.injury"). This will load the data into a variable called head.injury. If R says the head.injury data set is not found, you can try installing the package by issuing this command install.packages("DAAG") 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 head.injury R data set. The size of this file is about 68,856 bytes.

Minor Head Injury (Simulated) Data


The head.injury data frame has 3121 rows and 11 columns. The data were simulated according to a simple logistic regression model to match roughly the clinical characteristics of a sample of individuals who suffered minor head injuries.




This data frame contains the following columns:


age factor (0 = under 65, 1 = over 65).


amnesia before impact (less than 30 minutes = 0, more than 30 minutes =1).


(0 = no fracture, 1 = fracture).


Glasgow Coma Scale decrease (0 = no deterioration, 1 = deterioration).


initial Glasgow Coma Scale (0 = not ‘13’, 1 = ‘13’).


Glasgow Coma Scale after 2 hours (0 = not ‘15’, 1 = '15').


assessed by clinician as high risk for neurological intervention (0 = not high risk, 1 = high risk).


(0 = conscious, 1 = loss of consciousness).


(0 = no fracture, 1 = fracture)


(0 = no vomiting, 1 = vomiting)


any acute brain finding revealed on CT (0 = not present, 1 = present).
