similar to: R (&stats) newcomer.... help!

I am very new to R and programming and thank you in advance for your patience and help with a complete novice! I am working with a large multivariate data set that has 10 explanatory environmental variables (e.g. temp, depth) and over 60 response variables (each is a separate species). My data frame is set up like the simplified version below: JulianDay Temperature Salinity Depth Copepod

I''m working on user authentication system to get familiar with rails, and have basically solved most of my apps problems till now. I keep getting the NoMethodError, and can''t understand why.

I blogged about some of the problems with aaf in production (http://www.jroller.com/BrightCandle) yesterday but inspired by the poitive response I thought I would share the perceived problems and discuss some of the potential solutions to help newcomers and make aaf work as if by magic just like Rails does. All of these problems boil down to one simple problem, running acts as ferret in a

It's because we can't enter 'stocktrans2' from a telephone so we just hang up. The question is, why does it ask for the

I am ''raking'' my brain to fix this problem - I have searched, googled, looked through rake documentation, wiki.rubyonrails and I can''t fix...

My objective is to look at differences in two species of fish from morphometric measurements. My morphometric measurements are head length, eye diameter, snout length, and measurements from tail to each fin. I want to use discrimanant function analyis to determine if there are differences between the two species. I am familiar with R but new to discrimannt function analysis. I want to learn

Hello all, If someone could take a little time to help me then I would be very grateful. I studied piping plovers last summer. I watched each chick within a brood for 5 minutes and recorded behaviour, habitat use and foraging rate. There were two Sites, the first with 4 broods and the second with 3 broods. http://r.789695.n4.nabble.com/file/n4511178/Table_PP_Maslo_et_al.png As the data within a

I'm studying the calibration function in the survey package in preparation for raking some survey data. Results from the rake function below agree with other sources. When I run calibrate, I get a warning message and the M and F weights seem to be reversed. Even allowing for that, the deviation between calibrated and raked weights is much more than I expected. I see that in the calibrate

Dear all I have just had the question from a colleague. I know that it is not directly related to R (I will probably use R to do the analysis), but I hope someone can give us some insight: Thanks, AJ Smit I sampled populations of a seaweed in the intertidal in order to estimate the standing biomass of that seaweed at that site. Due to clumped distribution patterns, I chose a stratified

I installed wine1.5-amd64 package on my kubuntu 12.04 x86-64. I would like to install Microsoft .NET Framework 3.0 (x64). Winetricks can't help me with this, so I tried to do it manually.

Hi, I've got CentOS 5.3 installed as a Xen client installed. I've recently been trying to install TrueCrypt on the VM, but am having miserable troubles with the Fuse kernel module. To date, I've installed the following packages: yum install truecrypt yum install fuse However, to launch the fuse module, I need the dkms_autoinstaller running. However, when I try to start the

Hello everybody, In am trying to analyse a BACI experiment and I really want to do it with R (which I find really exciting). So, before moving on I though it would be a good idea to repeat some known experiments which are quite similar to my own. I tried to reproduce 2 published examples but without much success. The first one in particular is a published dataset analysed with SAS by
