On this R-data statistics page, you will find information about the nep499 data set which pertains to A study of Alzheimer's disease with eight SNPs and APOE. The nep499 data set is found in the gap R package. You can load the nep499 data set in R by issuing the following command at the console data("nep499"). This will load the data into a variable called nep499. If R says the nep499 data set is not found, you can try installing the package by issuing this command install.packages("gap") 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 nep499 R data set. The size of this file is about 24,535 bytes.
