Read in VPC data

Usage

read_vpc(sim, obs, psn_folder, software, sim_cols, obs_cols, verbose = FALSE)

sim: this is usually a data.frame with observed data, containing the independent and dependent variable, a column indicating the individual, and possibly covariates. E.g. load in from NONMEM using read_table_nm. However it can also be an object like a nlmixr or xpose object
obs: a data.frame with observed data, containing the independent and dependent variable, a column indicating the individual, and possibly covariates. E.g. load in from NONMEM using read_table_nm
psn_folder: instead of specifying "sim" and "obs", specify a PsN-generated VPC-folder
software: name of software platform using (e.g. nonmem, phoenix)
sim_cols: list for mapping simulation data columns, e.g. `list(dv = "DV", id = "ID", idv = "TIME", pred="PRED")`
obs_cols: list for mapping observation data columns, e.g. `list(dv = "DV", id = "ID", idv = "TIME", pred="PRED")`
verbose: show debugging information (TRUE or FALSE)

A list with names of "sim", "obs", "software", and "cols"
