Usually the double-precision representation is 64 bits in memory and, for the IA-32 processors (Intel and AMD x86 family), 80 bits in the floating point registers. Javier may be looking for options(digits = nn) where the default value of nn is 7. If you want more precision in printed results try setting options(digits = 12) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
