Readers, Have since tried to plot converted 24 hour data:
testtimedataset V1 1 13:01:41 2 13:02:10 3 13:02:38 4 13:03:05 5 13:03259 > testdata<-seq(1:5) > plot(testdata~testtimedataset) Error in function (formula, data = NULL, subset = NULL, na.action = na.fail, : invalid type (list) for variable 'testtimedataset' Was expecting to see a graph with ordinate values 1:5 for the time series values on the abscissa. What is the mistake please? -- r2151 ______________________________________________ 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.
