NlsyLinks-package: Utilities and kinship information for Behavior Genetics and...

Description Note Author(s) References Examples


Utilities and kinship information for Behavior Genetics and Developmental research using the NLSY.


This package considers both Gen1 and Gen2 subjects. "Gen1" refers to subjects in the original NLSY79 sample ( "Gen2" subjects are the biological children of the Gen1 females -ie, those in the NLSY79 Children and Young Adults sample (

The release version is available through CRAN by running install.packages('NlsyLinks'). The most recent development version is available through GitHub by running devtools::install_github (repo = 'LiveOak/NlsyLinks') (make sure devtools is already installed). If you're having trouble with the package, please install the development version. If this doesn't solve your problem, please create a new issue, or email Will.
