Hi, I have a dataframe wf existing of a header with different labels and beneath the values of those labels : wf: label1 label2 ... 0,45 0,21 0,10 0,45 .... .... I have a list fl <- c("label2","label3",..) Isn't possible to use the list elements in the list in order to subtract values from the dataframe? like : wf$fl[[1]] When I do in R I get :NULL

Hi, Is it possible to create new vars in a loop For instance: for (i in 1:11) var'i' <- assign something output = var1 var2 ... var11 Is there a way to combine/join the value of 'i' to the string/char var in de loop. -- View this message in context: http://www.nabble.com/join-chars-in-loops-tp16895854p16895854.html Sent from the R help mailing list archive at

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

Hello, i have problems with the ssh-daemon. Problem: sshd daemon would not start, complained about Not enough entropy in RNG The same message comes by ssh-keygen .

Hello, I am running Mandrake 8.0 I am installing & upgrading to Samba 3.0.28 I just finished reading IBM's Redbook "Open Your Windows with Samba on Linux" (redp3780). I'd like to know, what is the best configuration between SMB/CIFS & DFS, in a Linux (servers) & Windows (clients/workstations) network. Even though I read the Redbook, it still not clear as to which

I know R has a steep learning curve, but from where I stand the slope looks like a sheer cliff. I'm pawing through the available docs and have come across examples which come close to what I want but are proving difficult for me to modify for my use. Calculating simple group means is fairly straight forward: data(PlantGrowth) attach(PlantGrowth) stack(mean(unstack(PlantGrowth)))

Hi, I would like to iterate over a dataframe and plot several graphs over several pages. For instance, an iteration over the dataframe will result in 20 plots. Since 20 plots in one page is too much (too many small plots) I would like to distribute them over 5 pages with each 4 plots. I know how to create multiple plots on one page with : par(mfrow=c(2,2)) -- View this message in context:

I was up late last night trying to find the cause of this, but I''m stumped. I have this relatively simple controller to load up a bio. It''s basicly id, name, desc, type (I use STI). class BioController < ApplicationController layout ''layouts/singlepanel'' def index @bio = Bio.find(:all, :conditions => [''site_id = ?'',

Hi guys I'm hoping someone can help me with this. It should be easy but it seems to get stuck for no obvious reason! I am trying to set a report up in odfWeave so that we can re-run the same analysis at 3 time points as the data matures and provide an 'instant' report. To simplify the situation we have two pieces of data: site_id (numerical value 1-9) and reaction (categorical Y or

Is there a way to use has_many and have it operate like such? select * from pages where site_id = #{id} or site_id is null I know there''s finder_sql, but then I''ll lose the find_in_collection goodness.

Hi Maria If you have problems just start with a small model with predictions and then plot with xyplot the same applies to xyplot Try library(gamm4) spring <- dget(file = "G:/1/example.txt") str(spring) 'data.frame': 11744 obs. of 11 variables: $ WATERBODY_ID : Factor w/ 1994 levels "GB102021072830",..: 1 1 2 2 2 3 3 3 4 4 ... $ SITE_ID

Hi, I think I''m doing this the right way, but can''t get it going. I''m building a menu from the values in a mySQL table, and want to build it on the fly. This is something that should be working but only works halfway: <% @pages = Page.find(:all, :conditions => [''site_id = 4'']) %> <% @pages.each do |p| %> xyz <%p.id%> <%

Hi, I have three tables, a domain of Sites, a domain of Users, and a junction of Sites_Users with the tables named as such. My RoR application has a model and controller both User and Site. I tried to add a controller and model named Site_User but I can''t reference any functions in the controller, I get an Uninitialized Constant error. I''m very new to RoR, but not to

Hello, we are receiving some data, sample below - with a weird time/date stamp format, we need some help with R on converting this time date stamp to a useable field in R, date and time in a data-frame.

Dear all,? I hope that you can help me on this. I have been struggling to figure this out but I haven't found any solution. I am running a generalised mixed effect model, gamm4, for an ecology project.

I've added System Resource Controller Support with Socket Communications to Openssh. We are using this code since 2.9.9p2 on AIX 4.2 and 4.3 without problems. I've also tested the patched OpenSSH 3.1p1 on AIX 5.1. It's mainly based on examples from the IBM Redbook "Writing Reliable AIX Daemons". The SRC request handler supports START, STOP, REFRESH and STATUS requests

Hi, I'm again... I have been studying a documentation of IBM (the Redbook) about Samba. In this document says that to run the SWAT I can to run with any user, but to chance something I need to log as root. The document speak about version 2.0.x. About this, my question is: It's true for version 2.2.5? And, in this document says also that when I pass the password, it is going in text

Simon, Did you get a chance to review your AIX configuration? I'd be curious to know the differences with my own as while I have R installed, I still get the error related to libjpeg.a.
