output_data: export R data for NONMEM modeling

In amp.dm: Data Management Tools for Pharmacometrics

export R data for NONMEM modeling

Description

This function exports data for NONMEM modeling analyses including options that are frequently necessary to adapt.

Usage

output_data(
  x,
  csv = NULL,
  xpt = NULL,
  attr = NULL,
  verbose = TRUE,
  maxdig = 6,
  tonum = TRUE,
  firstesc = NULL,
  readonly = FALSE,
  overwrite = TRUE,
  ...
)

Arguments

x	data frame to be exported.
csv	character with the name of the csv file to generate
xpt	character with the name of the xpt file to generate
attr	character with the name of the rds file to generate
verbose	logical indicating if additional information should be written to the console
maxdig	numeric with the maximum number of decimals for numeric variables to be in output (see details)
tonum	logical indicating if all variables should be made numeric (standard for NONMEM input files)
firstesc	character with escape character for first variable, used to exclude row in NONMEM
readonly	logical indicating if the output csv file should be made readonly
overwrite	logical indicating if (all) output should be overwritten or not
...	Arguments passed to write.csv

Details

In case tonum is TRUE, all variables will be made numeric and Inf values will be set to NA (all NA values will be set to a dot). The rounding set in maxdig will only be done in case tonum is set to TRUE. For xpt files, the name of the object to export is used as the name of the dataset inside the xpt file (e.g. output_data(dfrm,xpt='dataset.xpt') will result in an xpt file named 'dataset.xpt' with one dataset named 'dfrm').

Value

a data frame is written to disk
