as.fun: The default is to return data as a data.frame. Pass a function (say tibble::as_tibble) in as.fun to convert to something else. If data.tables are wanted, use as.fun="data.table". The default can be configured using NMdataConf.
modelname: See ?NMscanData
col.model: See ?NMscanData
auto.ext: If auto.ext=TRUE, the file name extension will automatically be changed using the setting in NMdataConf()$file.phi - this by default means that the .phi extension will be used no matter what extension the provided file name has.
file.phi: Deprecated. Use file.
Returns
A list with a final parameter table and a table of the iterations
