round_output: Round Numeric Data (Any Level and Assay)

In invitroTKstats: In Vitro Toxicokinetic Data Processing and Analysis Pipeline

Round Numeric Data (Any Level and Assay)

Description

This function rounds the numeric columns from any level of processing. Numeric columns may include estimates of chemical-specific toxicokinetic (TK) parameters from the relevant in vitro assays or numerical data measurements collected from the mass spectrometry experiments.

Usage

round_output(
  FULL_FILENAME = NULL,
  data.in,
  FILENAME = "MYDATA",
  assay = NULL,
  level = NULL,
  exclusion.cols = NULL,
  sig.figs = 3,
  output.res = FALSE,
  INPUT.DIR = NULL,
  OUTPUT.DIR = NULL,
  verbose = TRUE
)

Arguments

FULL_FILENAME	(Character) A string used to identify the full filename of input .tsv or .RData file (i.e. "MYDATA-Clint-Level4.tsv" or "MYDATA-Clint-Level4Analysis-2025-04-23.RData"). The string is also used to name the exported data file (if chosen to be exported). (Note: FULL_FILENAME not required if data.in is provided.) (Defaults to NULL.)
data.in	(Data Frame) Any level data frame generated from invitroTKstats package. (Note: data.in not required if FULL_FILENAME is provided.)
FILENAME	(Character) A string used to name the start of the exported date file. Only required if input data is a data.frame and output file is being exported. (Defaults to "MYDATA".)
assay	(Character) A string used to name the assay used to generate the input data. The string is appended to the name of the exported data file. Only required if input data is a data.frame and output file is being exported. Must be one of the following assays: "Clint", "Caco-2", "fup-RED", or "fup-UC". (Defaults to NULL.)
level	(Character) A string used the name the level of the input data. The string is appended to the name of the exported data file. Only required if input data is a data.frame and output file is being exported. Must be one of the following levels: "0", "1", "2", "3", "4". (Defaults to NULL.)
exclusion.cols	(Character) Vector of column names to exclude from rounding. (Defaults to NULL.)
sig.figs	(Numeric) The number of significant figures to round the desired numeric columns to. (Defaults to 3.)
output.res	(Logical) When set to TRUE, the rounded data file will be exported to the user's per-session temporary directory as a .tsv (if data.in is specified or if FULL_FILENAME is a .tsv) or as an .RData (if FULL_FILENAME is an .RData). (Defaults to FALSE.)
INPUT.DIR	(Character) Path to the directory where the FULL_FILENAME exists. If NULL, looking for the input FULL_FILENAME in the current working directory. (Defaults to NULL.)
OUTPUT.DIR	(Character) Path to the directory to save the rounded data file. If NULL, the output file will be saved to the user's per-session temporary directory or INPUT.DIR if specified. (Defaults to NULL.)
verbose	(logical) Indicate whether printed statements should be shown. (Default is TRUE.)

Details

For example, for level-3 or level-4 output results, estimates of intrinsic hepatic clearance (Cl~int~) from Hepatocyte Incubation data, fraction unbound in plasma (F~up~) from Rapid Equilibrium Dialysis (RED) data, fraction unbound in plasma (F~up~) from Ultracentrifugation (UC) data, or apparent membrane permeability from a Caco-2 assay can all be rounded to the desired number of significant figures.

Note: Currently, for level-3 Caco-2 data, the "Frec_A2B.vec" and "Frec_B2A.vec" columns are not rounded. However, these columns can be rounded if the level-3 result table from calc_caco2_point is exported and the number of significant figures is specified.

The input to this function can be any level of data (level-0 through level-4) corresponding to any assay (Clint, Caco-2, Fup RED, Fup UC). The desired data object to be rounded can be a data.frame, specified with data.in, or a .tsv or .RData, specified with FULL_FILENAME.

If the rounded output file is chosen to be exported and an output directory is not specified, it will be exported to the user's R session temporary directory. This temporary directory is a per-session directory whose path can be found with the following code: tempdir(). For more details, see https://www.collinberke.com/til/posts/2023-10-24-temp-directories/.

As a best practice, INPUT.DIR (when importing a .tsv or .RData file) and/or OUTPUT.DIR should be specified to simplify the process of importing and exporting files. This practice ensures that the exported files can easily be found and will not be exported to a temporary directory.

Value

A rounded data frame

Examples

## Round Clint-L4 data, exclude p-value columns, and don't export results 
level4 <- invitroTKstats::clint_L4
round_output(data.in = level4,
             exclusion.cols = c("Clint.pValue", "Sat.pValue", "degrades.pValue"),
             output.res = FALSE)

## Round Clint-L4 data and export results. 
## Note: Will export as a .tsv file. 
## Not run: 
round_output(data.in = level4, assay = "Clint", level = "4")

## End(Not run)

## Round Clint-L4 .tsv data and export to INPUT.DIR. 
## Will need to replace FULL_FILENAME and INPUT.DIR with full filename and location of .tsv. 
## Not run: 
round_output(FULL_FILENAME = "Example-Clint-Level4.tsv", 
             INPUT.DIR = "<FULL_FILENAME FILE LOCATION>")

## End(Not run)

## Round Clint-L4 .RData and export to OUTPUT.DIR 
## Will need to replace FULL_FILENAME and INPUT.DIR with full filename and location
## of .RData. Will also need to replace OUTPUT.DIR with desired location of rounded 
## data file. 
## Not run: 
round_output(FULL_FILENAME = "Example-Clint-Level4Analysis-2025-04-17.RData",
             INPUT.DIR = "<FULL_FILENAME FILE LOCATION>",
             OUTPUT.DIR = "<DESIRED ROUNDED FILE LOCATION>")

## End(Not run)
