Fast data output to disk — write.csv.raw • iotools

A fast replacement of write.csv and write.table which saves the data as a raw vector rather than a character one.

write.csv.raw(x, file = "", append = FALSE, sep = ",", nsep="\t",
              col.names = !is.null(colnames(x)), fileEncoding = "")

write.table.raw(x, file = "", sep = " ", ...)

Arguments

x: object which is to be saved.
file: A connection object or a character string naming a file from which to save the output.
append: logical. Only used when file is a character string.
sep: field (column) separator.
nsep: index name separator (single character) or NA if no index names are included
col.names: logical. Should a raw of column names be writen.
fileEncoding: character string: if non-empty declares the encoding to be used on a file.
...: additional parameters to pass to write.table.raw.

Details

See as.output for the details of how various data types are converted to raw vectors (or character vectors when raw is not available).
