Dear all, I am looking at the R-help entry below: http://finzi.psych.upenn.edu/R/Rhelp02/archive/26640.html I have a more complicatedt problem. I have a zoo time series frame with 100+ sequences. I want to cycle through them back and forth and compare them to the 1st column at any time. I need also a button to click when I need the viewed-selected sequence (that is being compared to the

Hello, I have a zoo time series read from an excel file which has some dates the same, such as the following example: 02/10/1995 4925.5 30/10/1995 4915.9 23/01/1996 4963.5 23/01/1996 5009.2 04/03/1996 5031.9 # here 04/03/1996 5006.5 # here 03/04/1996 5069.2 03/05/1996 5103.7 31/05/1996 5107.1 01/07/1996 5153.1 02/08/1996 5151.7 Is there a

Hi, I have two zoo objects (time series of same frequency) say A and B. I need to exchange A's dates for B's. Is there and easy way? I managed to do it by converting A to a vector and pasting it on a zoo vector (all ones) with B's dates but I wonder if there is an easier way by some "zoo" command I have overlooked... Thanks in advance, Costas

Hello again, I merge different zoo time series with prices at different dates.

Dear list members, How can I shade the background area of a zoo time series object between specific dates? eg. library(tseries) library(zoo) SP500<-get.hist.quote("^GSPC", start = "1990-01-01", quote = "Close") plot(SP500) How can I produce the same plot but with a (say) red background between 2007-04-12 and 2008-05-14 ?

Dear list, I have an irregular time series saved and exported as a zoo object. What is the trick to force zoo to ignore the missing dates when reading it back in?

Hello everybody, I have two datasets, observed and predicted. Since my observed dataset is not in regular intervals, I need to filter my predicted dataset based on the measurement date of my observed data. Here, is an example similar to what I have library(chron);library(zoo) DATE<- seq(as.Date("2009-01-01"), as.Date("2009-05-01"), by = 1) mydat<- rnorm(length(DATE),

I have three columns in my raw data: date, time, and dry bulb temperature: http://r.789695.n4.nabble.com/file/n4495326/weathDataSDCoron.txt weathDataSDCoron.txt The date format is %Y%m%d and the time format is %H:%M. Any ideas on how to read it in such that it looks at the first two columns and then merges it into one column combining both the date and time? -- View this message in context:

Hi, I am an experienced developer with Windows and familiar with Linux. I am looking for a SIP solution. 1) How does Asterisk compare to VOCAL in terms of support. 2) Is Asterisk free? 3) Where are the docs? Or even better. Where do I start? 4) Will it run on RH9?

I am using a brand new RH9.0 installation. I installed Asterisk afterwards so I am not sure if Asterisk caused the problem below. The ps doesn't work. It could also be something else. I also tried installing a some video package. But I thought to ask here first if someone has seen this before.
