R Dataset / Package mi / nlsyV
On this R-data statistics page, you will find information about the nlsyV data set which pertains to National Longitudinal Survey of Youth Extract. The nlsyV data set is found in the mi R package. You can load the nlsyV data set in R by issuing the following command at the console data("nlsyV"). This will load the data into a variable called nlsyV. If R says the nlsyV data set is not found, you can try installing the package by issuing this command install.packages("mi") and then attempt to reload the data with the library() command. 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 nlsyV R data set. The size of this file is about 7,977 bytes.
