Hi all, I am trying to concatenate words together to create new column names, using a loop. Please consider the following toy example: x <- matrix(nrow = 1, ncol = 3) colnames(x) <- c("a", "b", "c") x[1,1] <- "1" x[1,2] <- "2" x[1,3] <- "3" I would like to create a new matrix with column names based on the column names

Hi, I'm trying to set up R to run a simulation of two populations in which every 3.5 days, the initial value of one of the populations is reset to 1.5. I'm simulation an experiment we did in which we fed Daphnia populations twice a week with algae, so I want the initial value of the algal population to reset to 1.5 twice a week to simulate that feeding. I've use for loops and if/else

Hello, I came up with this scenario of the use of batch mode while thinking of back-up schemes to use for myself. However, it could be that the last step needed in this scenario is not supported by rsync! Here's the scenario: At one time, /c/home/wer/work and /e/gold had identical content and were really huge (say, 200 GBytes). After some complex, intricate work, Mr. Wer

Hi, I'd like to know if it is possible to use wildcards * for indexing... E.g. I have a vector of strings. Now I'd like to select all elements which start with A_*? I'd also need to combine that with logical operators: "Select all elements of a vector that start with A (A*) OR that start with B (B*)" Probably that is quite easy. I looked into grep() which I think might

Hello, I am trying to make a search, using acts_as_ferret on a has_and_belongs_to_many relation : class a < ActiveRecord::Base belongs_to :b has_and_belongs_to_many :c Joboffer.find_by_contents( query +b_id:1 ) is working fine but Joboffer.find_by_contents( query +c:1 ) is not working Here are the tables descriptions: Table a have field : id, b_id Table b have field : id,

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
