Can I create a timeDate object using only year and week of the year values?
For a model I am working on, I have samples organized by year and week of the year. For this model, the data (year and week) comes from the basic sample data, but I require a value representing the amount of time since the sample was taken (actually, for the purpose of the model, it is sufficient to use the number of weeks from the middle of the sample week to the present).

'xtfrm' performance (influences 'order' performance) in R devel
Hello everybody, it looks like the presense of some (do know know which) S4 methods for a given S4 class degrades the performance of xtfrm (used in 'order' in new R-devel) by a factor of millions. This is for classes that ARE derived from numeric directly and thus should be quite trivial to convert to numeric. Consider the following example: setClass("TimeDateBase",

Hi One of the most important calculation in applied finance is the number of days between dates. That kind of calculus become annoying when a specific calendar must be used. That is the case for the business days calculus. The package timeDate has a function isBizday to perform that kind of thing. The problem is that using this function to calculate the number of business days between dates has

Rd \usage clause for an S4 replace method
Given S4 methods [ and [<-, how do I write the Rd-file usage clause for the latter one? What I have now is: \S4method{[}{TimeSeries,TimeDate,missing}(x, i, j, ..., drop) \S4method{[<-}{TimeSeries,TimeDate,missing,ANY}(x, i, j, ..., value) which results in the following output: ## S4 method for signature 'TimeSeries, TimeDate, missing': x[i, j, ..., drop]

Dealing with Non-Standard Hours
A data set I obtained has the hours running from 01 through 24 rather than the conventional 00 through 23. My favorite, strptime, balks at hour 24. I thought it would be easy to correct but it must be too late on Friday for my brain and caffeine isn't helping.
