R Dataset / Package boot / survival


On this R-data statistics page, you will find information about the survival data set which pertains to Survival of Rats after Radiation Doses. The survival data set is found in the boot R package. You can load the survival data set in R by issuing the following command at the console data("survival"). This will load the data into a variable called survival. If R says the survival data set is not found, you can try installing the package by issuing this command install.packages("boot") 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 survival R data set. The size of this file is about 136 bytes.
