Here is a sample of my data. KL <- read.table(header=TRUE, text='ID date 711 Dead 712 Uknown 713 20-11-08 714 11-28-07 301 302 09-02-02 303 09-21-02',stringsAsFactors = FALSE, fill =T) str(KL) data.frame': 7 obs. of 2 variables: $ ID : int 711 712 713 714 301 302 303 $ date: chr "Dead" "Uknown" "20-11-08" "11-28-07" . I wanted to convert the date column as follows. if (max(unique(nchar(as.character(KL$date==10) { KL$date <- as.Date(KL$date,"%m/%d/%Y") } but not working. How could I to remove the corresponding entire row. that do not have a date format and do the operation? thank you in advance __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
