export R data for NONMEM modeling

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

Value

a data frame is written to disk

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').

Examples

data(Theoph)
out_file <- tempfile(fileext = ".csv")
output_data(Theoph, csv = out_file, tonum = FALSE)
