In ?options: 'warning.expression': an R code expression to be called if a warning is generated, replacing the standard message. If non-null is called irrespective of the value of option 'warn'.
Is there a missing `it' between `non-null' and `is'? Best, Andy ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
