format_vpc_input_data: Prepare VPC data for future calculations by standardizing...

In ronkeizer/vpc: Create Visual Predictive Checks

Prepare VPC data for future calculations by standardizing column names and modifying the input data based on the limits of quantification, stratification, and logarithmic values.

Description

Prepare VPC data for future calculations by standardizing column names and modifying the input data based on the limits of quantification, stratification, and logarithmic values.

Usage

format_vpc_input_data(
  dat,
  cols,
  lloq,
  uloq,
  stratify,
  log_y,
  log_y_min,
  what = "observed",
  verbose = FALSE,
  pred_corr = FALSE
)

format_vpc_input_data_tte(
  dat,
  cols,
  stratify,
  rtte,
  rtte_calc_diff,
  what = "observed",
  verbose = FALSE
)

Arguments

dat	An input data.frame or similar object
cols	A list with an element for colname giving the name for colname in dat.
lloq	Number or NULL indicating lower limit of quantification. Default is NULL.
uloq	Number or NULL indicating upper limit of quantification. Default is NULL.
stratify	character vector of stratification variables. Only 1 or 2 stratification variables can be supplied.
log_y	Boolean indicting whether y-axis should be shown as logarithmic. Default is FALSE.
log_y_min	minimal value when using log_y argument. Default is 1e-3.
what	The description of the data (typically "observed" or "simulated")
verbose	show debugging information (TRUE or FALSE)
pred_corr	perform prediction-correction?
rtte	repeated time-to-event data? Default is FALSE (treat as single-event TTE)
rtte_calc_diff	recalculate time (T/F)? When simulating in NONMEM, you will probably need to set this to TRUE to recalculate the TIME to relative times between events (unless you output the time difference between events and specify that as independent variable to the vpc_tte() function.

Value

dat modified based on other inputs.

A named list with "dat" modified, as required, and "stratify" with the stratification parameters
