check_order: Perform a consistency check on observed and simulated data
Description
This function performs a simple consistency check on an observed and
simulated dataset to make sure they are consistent with respect to ordering
as required by the other functions used in the VPC calculation.
Usage
check_order(obs, sim, tol = 1e-05)
Value
The number of replicates contained in `sim`.
Arguments
obs, sim
A `data.frame` with 2 columns (see Details).
tol
A tolerance for comparing time values.
Details
The consistency check is performed by comparing a combination of unique
subject identifier (ID) and time. Both data.frame objects must be given with
those in positions 1 and 2, respectively.
