Currently the SORTEEDCQC package is not on CRAN, but you can install the development version from GitHub using the devtools package:
install.packages("devtools")
devtools::install_github("EIvimeyCook/SORTEEDCQC")
library(SORTEEDCQC)
The only function metRscreen is SORTEEDCQC().
library(SORTEEDCQC)
SORTEEDCQC()
