Hello, I am trying to come up with a routine to calculate a rolling mean and standard deviation for three parameters stored in a NetCDF file. The NetCDF file contains 10 years of daily records for each of the three parameters, and I need the statistics for each of the three parameters. Below I include some code illustrating what I've done so far. Obviously this approach does not get at the

I''ve been banging my head against this wall for several hours, and it hurts now so I''ll stop and ask someone. In one of my forms I had been using a statement to extract the current year for use with some form field calculations. <% currentyear = DateTime.now.year %> And then further down several date_selects like the following, <%= date_select

Given a Date object or simply a year is there an R function to tell me if the it is a leap year or not? I was hoping for something like 'is.leapyear'. I probably can build my own function (year divisible by 4 etc.) but I would rather use an existing function if it is available. Thank you. Kevin

Dear R helper: When I was trying to install the fCalendar package, R report the following error and then my installation failed: * Installing *source* package 'fCalendar' ... ** R ** inst ** preparing package for lazy loading Loading required package: MASS Loading required package: fEcofin Loading required package: fUtilities Loading required package: RUnit RUnit 0.4.17 loaded.

In the dial plan, with GotoIf...is there a way to do a logical negation(NOT)? I want to check if the year is a leap year and the below code is how I would write the check in C. According to the wiki there isn't a logical NOT as a valid expression. From reading the asterisk/docs/README.variables, this seems to be missing. int year = 2005; if ( (year % 4 = 0) && !(year % 100 =

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",

How do I sum 15 years to my dataset? original dataset dates val 1 2001-01-12 1.2 2 2001-02-12 1.2 3 2001-03-12 1.2 result dates val 1 2016-01-12 1.2 2 2016-02-12 1.2 3 2016-03-12 1.2
