Hello, It seems that there is a problem with ":". If you only need the date, you can use as.Date(Sys.time()) instead of the complete form. If you need the time, you can try the following commands which change the ":" into "-" :
newsystime<-<-format(Sys.time(),"%Y-%m-%d-%H-%M-%S") write.csv(data.frame(recovery_rates = rr), file = paste("recovery_rates_at_", newsystime, ".csv", sep = ""), row.names = FALSE) Have a good day, Ptit Bleu. -- View this message in context: http://r.789695.n4.nabble.com/How-to-use-Sys-time-while-writing-a-csv-file-name-tp4635358p4635363.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.
