The error is just a misleading error message. loading the data produced column sdate as > str(prostate) $ sdate :Classes 'labelled', 'dates' atomic [1:502] 2778 2820 2933 2999 3002 ... .. ..- attr(*, "format")= symbol ddmmmyy .. ..- attr(*, "label")= chr "Date on study"
prostate$sdate <- as.Date(prostate$sdate,origin="1970-01-01") # fixes the problem and 'describe' runs just as a comment: maybe the R dataset should have sdate as a Date class. -- View this message in context: http://r.789695.n4.nabble.com/Hmisc-describe-error-tp4644708p4644711.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
