Well, that's enough to get the numbers into R. You then will have to work out what they mean. readBin(connection, numeric(), size=4, n=whatever) will read `whatever' Fortran single precision numbers from `connection'. If you are doing this on the machine where the file was generated then you don't need to worry about endianness. On a different machine (eg moving from a Sparc to a PC) you may need to add endian="swap". Look at readBin for more information. -thomas ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
