I am completely misunderstanding how to handle dates. I want to plot a couple of data series against some dates. Simple example 1 below works fine. Unfortunately I have multiple observations per day (no time breakdowns) and observations across years. (example 2 very simplistic version )
Can anyone suggest a quick fix or point me to something to read? I thought that zoo might do it but I seem to be missing something there too. Any suggestions gratefully recieved. Example 1 consecutive dates same year. ================================================= x <- "days 9/26/09 9/27/06 9/28/06 9/29/06 9/29/06 9/29/06 10/1/06 10/1/06 10/2/06 10/3/06" mydata <- read.table(textConnection(x), header=TRUE, as.is=TRUE); mydata mydates <- as.Date(mydata[,1], "%m/%d/%y"); mydates mynums <- rnorm(10) plot(mydates, mynums) ================================================ Example 2 (things go blooy!) non-consecutive dates different years. ================================================= x <- "days 9/26/09 9/27/06 9/28/06 9/29/06 9/29/06 9/29/06 10/1/07 # <- year changes 10/1/07 10/2/07 10/3/07" mydata <- read.table(textConnection(x), header=TRUE, as.is=TRUE); mydata mydates <- as.Date(mydata[,1], "%m/%d/%y"); mydates mynums <- rnorm(10) plot(mydates, mynums) ______________________________________________ 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.
