How to convert number (matlab) to date
Hello I am new to R and I need to convert some dates (numeric format by matlab) to actual dates in R. For instance, Matlab -> 730456 -> >> datestr(730456) ans = 02-Dec-1999 R - > library(zoo) > as.Date(730456) [1] "3969-12-03" I don''t not mind the output format but it needs to be right. Many thanks Ed

partial autocorrelation for Rt vs. Nt-1, ......., Nt-h
Dear list, following a previous querry we are still stuck! As pointed out by Erin Hodges the "ts" library includes a PACF function which reports the partial correlation of population density at time t against lagged population density. However, what we are trying to calculate is the partial correlation between rate of population change, Rt=log Nt/Nt-1, against lagged population

where do I report this DateTime bug?
I have isolated what appears to be a bug in the Rails extensions to DateTime, but I don''t know where to report it. I have a standalone file to demonstrate the bug, but the punch line is that this code: TestRecord.create!(:f_datetime => (expected = DateTime.jd(2000000))) found = TestRecord.first.f_datetime puts("expected == found => #{expected == found}")

Making an HTTP request to an external machine
During one of my controller actions I want to call an external machine before I do anything. It''s not a real web service, more like a REST-style thing where I''ll just be tweaking a servlet running on another machine and sending it some data. Does Rails give me anything to work with for doing that? I read the web service stuff but it''s overkill for what I need. I

An idea: add RYUL to Rails
Dear Friends, I''d like to have a development suggestion for Rails. Rails is an amazing framework, and clearly it''s weakest link is that it relies on HTML in the end, which is not always the most appropriate GUI out there. Another option could be XUL. Mozilla-based browsers (Firefox) can run XUL apps right out of the box, others could use the XULRunner application. Here you can

Best Practice for Returning to Calling Page?
I have a partial, it''s a shopping cart display, it''s designed to appear on several different pages of my site. One of the buttons on the shopping cart empties the cart, and then I want the calling page to redisplay. In other words, the cart controller needs to return the visitor to the same page -- however since the cart could appear on any given page, this has to be

Truncating dates (and other date-time manipulations)
Dear all, I''ve been struggling to perform common operations on dates that I need to be able to correct draw date-time scales - in particular I need to be able to round/truncate/ceiling dates to arbitrary precision - e.g. to weeks, months or years (or multiples thereof). I haven''t been able to find anything to do this in base R (trunc.Date only truncates to sub-day
