I have a class "tframe" with more specific classes indicating how time is being represented, such as > class(tframe(data)) [1] "ts" "tframe" but now "[.ts" produces warning messages > tframe(data)[2] Warning: Not returning a time series object [1] 2006.25 Even my simplest tests produce hundreds of lines of warnings, so I've commented out

I'm having some trouble figuring out latest.start in the tframe package. The results seem a bit cloudy. Sample session: > library(ts) > library(tframe) Loading required package: syskern > t1<-ts(c(1,2,3,4,5),start=1) > t2<-ts(c(1,2,3,4,5),start=2) > earliest.start(tbind(t1,t2)) [1] 1 1 > earliest.start(tbind(t2,t1)) [1] 1 1 > latest.start(tbind(t2,t1)) [1] 1 1

Below are a few problems I have encountered with the new checks being done in R-devel. 1/ I have two generics, test.equal and test.equal.tframe. The first checks that two objects are equal while the second checks if two objects have equal tframes (time frames). There is no reason these should have similar arguments but the check seems to think that test.equal.tframe is a method for test.equal so

I have an object with an attribute "tframe" for which there is a generic method print.tframe and also a method print.tframe.default defined in a library. However, when I use attributes(object) I get the message $tframe Error: couldn't find function "print.tframe" It's as if <primitive: attributes> is not looking through the search list? Any suggestions?

"[<-" in R 0.63 does not appear to strip attributes, whereas Splus and previous versions of R did.

There is now a preliminary version of a time series package in the R-devel snapshots, and we would welcome feedback on it. It is based in part on the packages bats (Martyn Plummer) and tseries (Adrian Trapletti) and in part on code I had or have written. (Thanks for the contributions, Martyn and Adrian!) Some of the existing ts code has been changed, for example to plot multiple time series, so

After long but intermittent discussion (it was mentioned at DSC99, for example), we have reorganized the standard packages, with base graphics stats utils methods normally loaded, mle splines stepfun tcltk tools available for loading, and ctest eda lqs modreg mva nls ts as stub packages which ensure back-compatibility. (These have all been merged into stats except lqs which rejoins

I am having problems with the package dse. I just installed R 2.2.1 and reinstalled all packages. I am running Windows XP Pro with all updates. Below there are two examples of error messages generated when trying to execute some simple programs. The code was taken directly from the package documentation. Any help on this will be greatly appreciated. Merry Christmas Fernando

Hi, I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings. Thanks in advance. Payam > simplevar <- function(wframe,column1,column2) { + tframe <- get(wframe) + x1 <- which(names(wframe)==column1) + x2 <-

Hi, As a project for a computer performance analysis paper I am taking this semester, I am going to look at the performance of the memory manager in R, with the aim of determining how fast it is and which areas most need improvement. The idea is that I will compare various versions of R, starting with 0.64.2, and then at a few stages in the implementation of the new memory management scheme (of

Hello, I have two time series objects, 1 is yearly (population) and the other is quarterly (bankruptcy statistics). I would like to produce a quarterly time series object that consists of bankruptcy/population. Is there a pre-built function to intelligently divide these time series: br.ts = ts(data=br.df[,-1], frequency = 4, start=c(2001,1), end=c(2008,2)) distPop.ts = ts(data=distPop.df[,-1],

Hi, I have two questions about ts. (1) How do I subset a ts object and still preserve the time index? for example: > x=ts(1:10, frequency = 4, start = c(1959, 2)) # the ts object > x Qtr1 Qtr2 Qtr3 Qtr4 1959 1 2 3 1960 4 5 6 7 1961 8 9 10 I don't want the 1st 2 elements, so I could subset like this: > x[3:length(x)] [1] 3 4 5 6 7 8 9 10

The following seems confused (0.65 snapshot) > x <- ts(1:20) > window(x, 1, 1) Time Series: Start = c(1, 1) End = c(1, 1) Frequency = 1 [1] 1 Warning message: Not returning a time series object in: [.ts(x, i) (it of class ts, as the print method shows). Under 0.64.2 it is even more confusing: > x <- ts(1:20) > window(x, 1, 1) Warning: Not returning a time series object
