readAsRaw takes a connection or file name and reads it into
a raw type.
readAsRaw(con, n, nmax, fileEncoding="")readAsRaw returns a raw type which can then be consumed
by functions like mstrsplit and dstrsplit.
A connection object or a character string naming a file from which to save the output.
Expected number of bytes to read. Set to 65536L by
default when con is a connection, and set to the file size
by default when con is a character string.
Maximum number of bytes to read; missing of Inf
to read in the entire connection.
When con is a connection, the file encoding
to use to open the connection.
