With dev testthat, I see

checking examples ... ERROR

The error most likely occurred in:

i get the following error when i tried the ELCC program in jupyter

Error in library(NREL/repra): 'package' must be of length 1
Traceback:

1. library(NREL/repra)
2. stop("'package' must be of length 1")

can we run the code directly in jupyter notebook? is there something else that needs to be installed?
