The hemp package

The hemp package contains data sets and the functions used in Desjardins and Bulut (2018)'s book Handbook of Educational Measurement and Psychometrics Using R published by CRC Press.

Additionally, the functions in hemp can be used to conduct data analysis with classical test theory and generalizability theory.

To install the hemp package:

install.packages("devtools")
devtools::install_github("cddesja/hemp")

If you're not using the most recent version of R, then the installation may not continue properly. If this is the case, you can use:

Sys.setenv(R_REMOTES_NO_ERRORS_FROM_WARNINGS=TRUE) # in case your R version is older
devtools::install_github("cddesja/hemp")
