Hello, After putting together interaction code that worked for a single pair of interactions, when I try to evaluate two pairs of interactions( flowers*gopher, flowers*rockiness) my computer runs out of memory, and the larger desktop I use just doesn't go anywhere after about 20 minutes. Is it really that big a calculation? to start: mle2(minuslogl = Lily_sum$seedlings ~ dnbinom(mu = a,

Dear all, can anybody help me with the program below? The function predict.lda seems to be defined but cannot be used by errortest. The R version is 1.7.1 Thanks in advance, Stefan ---------------- library("MASS"); library("ipred"); data(iris3); tr <- sample(1:50, 25); train <- rbind(iris3[tr,,1], iris3[tr,,2], iris3[tr,,3]); test <- rbind(iris3[-tr,,1],

How come I allways immediately run into difficult stuff when I''m trying some new programming language? Am I blind for the simplicity of Ruby/Rail, which a see must be there? Anyway, don''t try and answer this rhetoric question. I have got another one for you, seemingly difficult. I''m struggling with a n:m relationship (in a database, that is) and its join table.

Dear R-gurus, We are planning an experiment to test if plants produced by selfing are less fit than those produced by outcrossing. We have plants from three different alpine valleys, picked randomly among all the possible valleys. In each valley, we have a number of individuals, also picked at random. seeds from this individuals were brought back to the green house and sawned. when they

Hi ! We study the effect of several variables on fruit set for 44 individuals (plants). For each individual, we have the number of fruits, the number of flowers and a value for each variable. Here is our first model in R : y <- cbind(indnbfruits,indnbflowers); model1 <-glm(y~red*yellow+I(red^2)+I(yellow^2)+densite8+I(densite8^2)+freq8_4+I (freq8_4^2), quasibinomial); - We have

Hi, I am new to this list as a poster, but a reader for some time. I've using R for several weeks now, and I have a lot of questions about certain procedures. Here I go: I want to test if there are differences in the time spent by pollinators visiting flowers of a given plant species, according to a number of experimental manipulations made on those flowers. All experimental

When I run ogginfo on a .ogg file I created with oggenc (RC3), it lists some things that I have questions about: 1. Ogginfo lists bitrate_average and bitrate_nominal. Now, bitrate_average (I assume) would mean the overall bitrate average for the entire file but what does bitrate_nominal mean? 2. How is the serial number created? Can I tell something specific about an .ogg file by looking at it?

hi! I apologize in advance if this is a newbie dumm question, but I really can't figure it ou. I have lists of sumeric and character data on some URLs, which look like this: <photo id="5876248819" owner="13716719 at N04" secret="faf9bb7f52" server="5264" farm="6" title="our rose garden" ispublic="1"

Using sudo and rsync to perform migrations of source from test to prod When the rsync 'source' 'target' are both on the local server the owner:group is maintained from the source When the copy is 'source' local 'target' remote the owner:group changes to the value specified by uid:gid in the rsyncd.conf I want the 'target' to always change to uid:gid

Hi folks, I am new to the R software. I have been going through different materials to know more about R. I have the R software installed on my windows machine.I would like to know the R source code for the following problems on iris flower data set. I need to do the cluster analysis project with the iris data set. The goal is to cluster the flowers according to their Sepal.Length, Sepal.Width,

Hello. I need to know how can R compute AIC when I study a regression model? For example, if I use these data: growth tannin 1 12 0 2 10 1 3 8 2 4 11 3 5 6 4 6 7 5 7 2 6 8 3 7 9 3 8 and I do model <- lm (growth ~ tannin) AIC(model) R responses: 38.75990 I know the following formula to compute AIC: AIC=

Dear All, I've tried to sum columns -- different species of flowers, fruits plus twigs -- with NAs to get litterfall/trap, and then after use litterfall to calculate production (litterfall (grams)/ hectare/ day. But R 'sees' litterfall/trap as a string. My question: How to use basic mathematical functions to deal with NAs in data management. Example (as you can note I have many

Hi all, I have multiple textboxes containing numbers. I want to add up all the numbers and show the sum. Can I select the textboxes by class and sum the content? This also has to happen realtime: when a number is changed ina textbox the sum should also change. can this be done? regards, Stijn --~--~---------~--~----~------------~-------~--~----~ You received this message because you are

I was trying to write a wrapper for number_to_currency to return currency in pounds. I used a helper class to do this. def number_to_pounds(amt) number_to_currency(amt, :unit => "£") end This works fine, but I am trying to understand why I can''t use a symbol to pass the values. I thought symbols were like pointers. (you now know I am a newbie). def

Hello, I'm working in adding support for 64-bit integers to my target. I'm using LLVM to decompose the 64-bit integer operations by using 32-bit registers wherever possible and emulating support where not. When looking at the bit shift decomposition I saw what seems to be a bug in the implementation. The affected function is ExpandShiftWithUnknownAmountBit in LegalizeIntegerTypes.cpp.

Hi Duncan, The problem is the implementation of the expansion. Perhaps an example can help illustrate better. Take the case of a 64-bit integer shifted left by say 6 bits and is decomposed using 32-bit registers. Because 6 is less than the 32 (the register size) the resulting low part should be equal to the source low part shifted left by 6 bits. The current implementation places a zero

Hi, I'm trying to copy the first row of one data frame to another. This is the statement I am using : df2[1,]<-df1[1,]; I have printed them out separately: df1[1,] = A C D E F But after copying: df2[1,] = 96 29 88 122 68 Why isn't it copying? They are both data frames, and "as.character" isn't working either. Thanks for your input :) [[alternative HTML version
