check_order: Perform a consistency check on observed and simulated data.

Description Usage Arguments Details Value See Also Examples

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

1
check_order(obs, sim, tol = 1e-05)

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's must be given with those in positions 1 and 2 repectively.

Value

The number of replicates contained in 'sim'.

See Also

observed, simulated.
