R: ts - objects
Hello, I faced some difficulties using time series objects. ---------------------------------------------------------------------------- 1. Why is the time data changed, when I, e.g., apply sqrt(arrts), but not when arrts^0.5 ? This is my examples time series: ---------------------------------------------------------------------------- > arrts Time Series: Start = 3 End = 23 Frequency

Precision error in time index of ts objects
I should have formulated my question in a more specific way. 1. I suspect this is a floating point precision issue. I am not very knowledgeable about R internals, can someone else confirm it? 2. Should this be considered a bug or not, because it is "just a precision issue"? Should I report it? 3. How can it happen? From a quick review of ts.R, it looks like the values of the time

Precision error in time index of ts objects
Thanks for the very detailed explanation. I did not create the series using structure(), that was the result of dump() on an intermediate object created within tsdisagg::ta(), which is where I found the error in the first place. ta() indeed manipulates .Tsp directly, rather than using ts. I guess this is a bug in tsdisagg then. Thanks! -- Andrea Altomani On Sat, Sep 2, 2017 at 12:31 AM

As a simple example consider the following two descriptions

Preliminary version of ts package
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

still problem with installation of locfit on DEC alphaev56-dec-osf4.0d
Dear all, after building the R-1.1.1 from source on our alpha everything seems to work, but locfit still hangs... I installed locfit with install.packages(...), the installation process went fine, but calling locfit() blocks the R environment. Has anybody got an idea howto get to the roots of this problem?

mixing different modes of lty line type specification in legend() ?
Hi List, is sth. like the following possible: legend(x,y,c("A","B","C"), lty=list(1,"42","11")) ? Or: is there a possibility to define a solid line using the "string" mode for lty?

using browser() in complex programs - where am I?
Dear all, is there an easy way to know at which position in the source code browser() (or stop()) was called? This seems to be important for me when I try to debug a program (e.g. using options(error=quote(dump.frames()))) traceback() returns some information, but I miss something like a line number, e.g. "stopped at line 999 in foo.R".

ts.intersect a multivariate and univariate ts
This seems like a FAQ, but I can't figure it out. I have a mv ts object: R > tsp(pg) [1] 1982 2003 1 R > dim(pg) [1] 22 12 and a univariate ts: R > tsp(rw) [1] 1690 1996 1 Yet, when I try to intersect them: R > tsp(ts.intersect(rw, pg)) [1] 1982 2176 1 the process goes awry. How to I get rw and pg to be one ts that runs from 1982 to 1996 and has 13 univariate time
