Read a cohort saved with cohort_save()

Source: R/io.R
cohort_read.Rd

Reads the RDS file, checks it is a cohort file, and re-validates the cohort before returning it. A cohort saved by an older version of the package gets the default for each property added since then, and a subject QC flag saved by biocohort 0.1.x as qc_status/qc_reason in subject_tbl is renamed to subject_qc_status/subject_qc_reason, the names cohort_qc() now uses.

Usage

cohort_read(path)

Arguments

path

Path to a file written by cohort_save().

Value

The Cohort object.
