save.data: R Utilities: Saving/Writing Data Files using miceadds

Description

This function is a wrapper function for saving or writing data frames or matrices.

Usage

save.data( data, filename, type="Rdata", path=getwd(), row.names=FALSE, na=NULL,  suffix = NULL , suffix_space = "__" , index = FALSE , systime = FALSE , ...)

Arguments

data

Data frame or matrix to be saved

filename

Name of data file

type

The type of file in which the data frame or matrix should be loaded. This can be Rdata (for R binary format, using base::save, csv (using utils::write.csv2), csv (using utils::write.csv), table (using utils::write.table) or sav (using sjmisc::write_spss). type can also be a vector if the data frame should be saved in multiple formats.

path

Directory from which the dataset should be loaded

row.names

Optional logical indicating whether row names should be included in saved csv or csv2 files.

na

Missing value handling. The default is "" for type="csv" and type="csv2" and is "." for type="table".

suffix

Optional suffix in file name.

suffix_space

Optional place holder if a suffix is used.

index

Optional logical indicating whether an index should be included in the first column using the function index.dataframe.

systime

If index=TRUE, this optional logical indicates whether a time stamp should be included in the second column.

...

Further arguments to be passed to save, write.csv2, write.csv, write.table or sjmisc::write_spss.
