easily write a csv file compatible with nonmem

write_nonmem(
  x,
  file,
  sep = ",",
  row.names = FALSE,
  na = ".",
  quote = FALSE,
  ...
)

Arguments

x	dataframe to be written to csv
file	character string naming a file or connection open for writing.
sep	field string separator, defaults to comma (",")
row.names	logical value whether to include row names
na	value for NA
quote	whether character or factor columns should be surrounded by double quotes
...	remaining arguments passed to data.table::fwrite

nonmem uses '.' for NA values, does not like quotes in column names and does not handle row names, so these are all presets
