Usage

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.
