Dear all, I am using R CMD SHLIB to compile a c++ code into a library (.so) and dyn.load to load this library into a R code. I am facing some problems in the c++ code that I can not figure out how to solve. Do you recomend any good way to debug this R + C++ program? If I was programming only in C++ I would use GDB. I would much appreciate any help or suggestion! Best regards, Charles -- Um

Dear all, Happy New Year for all of you! I hope we have an year of essential freedom for everyone! I am trying to manipulate a matrix in order to know in which column and in which row a number is allocated. But, when we use the function "which" it returns the position of the number in the "vector representation of the matrix". For example: >

Dear all, I need to access data from a large matrix (48000 x 48000) and to do it I am trying to run two loops using "for" command. Surely it is been a very slow job. I heard that "for" is not the best option to perform large loops in R, but I don't really know what would be the best (fast) option. sapply? vapply? Could anyone help me with this issue, please? Thank you

Hi everyone, I am a newbie in R and in this discussion list. I am trying to use R package "ncdf" to read values of temperature from a NCDF file. I did it before to another file using the function "get.var.ncdf", but now there is an error that I can not solve, and I would really appreciate if you could help me. I am using R version 2.11.1 (2010-05-31) in a machine with Linux

Readers, For a 12 hour time stamp: > testtime<-("2013-01-01 01:00:01 PM") > testtime [1] "2013-01-01 01:00:01 PM" > testtime24hour<-strftime(testtime,'%H:%M:%S') > testtime24hour [1] "01:00:01" how to convert to 24 hour format so that the object 'testtime24hour' is: '13:00:01' Thanks. -- r2151

I have a basic model class TestTime with no customization. class TestTime < ActiveRecord::Base end I would like to pass the following SQL fragment as part of an AR save call to TestTime objects. How and where would I do this in the model? "set c_time=current_time" (current_time is an SQL method, not a variable). -- Posted via http://www.ruby-forum.com/.

UseRs, I am working on a dataset (see small example below) where individuals were followed on a specific date-time combo and multiple repeated measurements were taken (e.g., height in meters, behavior class in 2 letter code). Observation numbers varied between individual (ranging from 1 observation for each date-time combo to >50) I am trying to summarize the data into 1 row per

All, I am having trouble with a "read.table()" function that is inside of another function. But if I call the function by itself, it works fine. Moreover, if I run the script on a Mac OS X (with the default Mac OS X version of R installed, rev 2.8), it works fine. But it does not work if I run it on windows vista (also default Windows version of R, rev. 2.8). Again, both

Dear all, I work with (vibrational) spectra: some kind of intensity (I) over frequency (nu), wavelength or the like. I want to do fourier transform for interpolation, smoothing, etc. My problem is that the spectra are often irregularly spaced in nu: the difference between 2 neighbouring nu varies across the spectrum, and data points may be missing. Searching for discrete fourier transform

A new version of tseries (0.9-10) has been uploaded to CRAN. The new version contains the class "irts" for irregularly spaced time series. Irregular time series are basically time series where each observation (uni- or multivariate) has a time-stamp represented by an object of class "POSIXct". It provides some basic functionality such as reading and writing irregular time

I have a set of modeled climate data recorded at irregular intervals. The format of the data is such that there are monthly measurements for the years 2000, 2020, 2050, 2080, etc. Therefore I have 12 regular records, a skip of some number of years, then 12 more monthly records, another skip, and so on.... I created a dataframe from .txt with the read.table() command. For starters I need

Hi, Could you please advice some easy way to do the following for a dataframe (header=F) having unequal column- & row- length. 1. Combine/stack/join contents from - a) multiple rows into one column. b) multiple columns into one row. 2. Stack contents from multiple columns (or, rows) into one column (or, row). Thank you.

Hello R users, I'm a newby to R (and programming software at large) and I would need some help to sum up event data at discreet time and irregular time interval into a hourly frequency. Here is an example of my time series frame (irregular time-serie object - irts in the tseries package): time value 2008-12-19 19:11:03 GMT 1 2008-12-19 19:12:00 GMT 0 2008-12-19

Hi, I need to maintain a same user/group list on multiples systems. Can we just copy the same passwd and groups file on all machines? If we create a new user on one system then I will need to copy this to all other systems. This is quite cumbersome. Any suggestions? - CS.
