Hi, As I sit and learn how to work with time series, I've run into a problem that is eluding a quick easy answer (and googling for answers seems to really slow the process...) Question #1-- In a simple example on R 3.3.1 (sorry my employer hasn't upgraded to 3.3.2 yet): x=rnorm(26,0,1) x.ts<-ts(x,start=c(2014,9),frequency=12) inputting x.ts at the prompt gives me a table with the rooms denoted by year and columns denoted by months and everything lines up wonderfully. Now my problem comes when I type at the prompt plot(x.ts) or plot(x.ts, xlab="") or plot.ts(x.ts,xlab="") I get a plot of the values, but my x-axis labels are 2015.0, 2015.5, 2016.0, and 2016.5 . January 2015 is coming out as 2015.0... Is there a way of getting a more intelligible x-axis labeling? Even 2015.1 for Janaury, etc. would work, or even getting an index (either Septemebr 2014 representing 0 or 1 and it incrementally increasing each month). Question #2-- If I have a time series of decadal events, how best should I set the frequency. It is historical data, in the form of say AD 610-619 5 events, AD 620-629 7 events, etc. Sorry for such a basic questions. Any advice would be appreciated. Thanks in advance, MEH Mark E.
