Re: [R] R time series analysis
You also may want to look at auto.arima in the 'forecast' package, which will return the best ARIMA model based on AIC/AICc/BIC values ?auto.arima hth c On 09/05/2010 06:02 PM, Stephan Kolassa wrote: Hi, basically, you know 5 periods later. If you use a good error measure, that is. I am a big believer in AIC for model selection. I believe that arima() also gives you the AIC of a fitted model, or try AIC(arima1). Other ideas include keeping a holdout sample or some such. I'd recommend looking at a time series textbook.

[R] Axes=F and plotting dual y axes
Howdy. Been running into a bit of trouble with plotting. Seems that axes=F is not working. Whenever I plot (either a dataframe or xts/zoo series) and I set axes=F along with xlab/ylab= I still get the default axes printed in my chart. Consider this: #Create some sample data, both 50 units of blah series2 = c(1:50) series1 = rep(25:74) testdf1 = as.data.frame(series1) testdf1$series2 = series2 As a note, I converted my original xts/zoo dataset into a dataframe thinking it could be weirdness on the part of that. I just did this here to have something reproducible since it's not feasible to put my entire original dataset in the email. plot(testdf1[,1], main=Woo, col=rich12equal, xlab=, ylab=, axes=F, type='l') It still displays the x and y axes. What I'm trying to do: par(new=T) plot(testdf1[,2], ...) and from there I can manually label the axes, title, etc. Any idea what's going on? I'm using R 2.10.1 on ubuntu (I probably need to upgrade via debian packages soon) Regards, CJ ps: I am trying to accomplish this, as seen here: http://blog.earlh.com/index.php/2009/07/multiple-y-axes-in-r-plots-part-9-in-a-series/ -- but axes=F is giving me trouble. __ 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.
Re: [R] Axes=F and plotting dual y axes
That worked. Stupid me forgot that I had the stock ticker 'F' assigned in my workspace. Well.. guess I'll hit myself with a 2x4 now..
