Hi All, I am developing a package that requires information about the location of a set of files that will be used often in the calculations. In my current version, I define the location in the main file that calls all the subfunctions. This works fine when you are installing from source, but will not work so well if I want people to be able to install binary versions of the package. Therefore, I

Hi All, I'm hoping someone else can help me out with this. I am doing some matrix algebra using sub-parts of matrices, and sometimes I need only a single row/column of the original matrix. However, whenever I pull out only a single row/column, R returns a row vector, but often this will break my matrix algebra. Is there any *easy* way to get R to remember what the single row/column came out

Say I have a tab-delimited table I want to read into R. What should I expect to happen if some of the entries contain the character " ' "? I thought it would read the file fine, but that is not what happens. Instead, all the values in between two " ' "s get read into one field, and things are just seriously messed up. Is this a bug, and besides removing the offending

Doing package development on a Windows 7 machine, and I want to tell R check not to worry about the "suggested" packages. I realize this can be done using the ~/.R/check.Renviron file, but what directory corresponds to "~"? Is that supposed to be the user directory? Or is it some other directory? I have this _R_CHECK_FORCE_SUGGESTS_=false (have also tried FALSE) in

Hi All, I was wondering if there would be any interest in adding an option to the "save" function in R that I think would be useful. I was thinking that it might be useful to have an option that would generate a ".sessionInfo" variable that contains the output of "sessionInfo()", and adds it to the list of objects to be saved. This way, whenever an RData object is

In R on Windows (ver 7) I have somehow set the preferences for the R console window to be always on top. I'm sure at the time I did this it seemed like a good idea, but in practice it is not. Unfortunately, I cannot remember where the setting is changed, and thus it is stuck this way. Does anyone know how to modify this setting? Thanks, -Robert Robert M. Flight, Ph.D. Bioinformatics and

Hi All, I don't know if such a thing exists, but I am looking for a way to better keep track of where data is going, how it is being modified, and what functions are acting upon it when I give the data over to a function that calls many subfunctions (as happens in my current package I am working on), or in an R script I am using to do multiple processing steps on data. Currently I find it

I would like to perform partial mantel tests on only within group values, with "between group" values assigned to NA. This is possible in package ncf partial.mantel.test, however this sues a different permutation to that used in ecodist.ecodist will not accept data with NA values, returning a "matrix is not square error. is it possible to perform this test in ecodist? many thanks

Dear All, I am new for R and SEM. I try to fit the model with Y (ordinal outcome), X (4 categorical data), M1-M3 (continuous), and 2 covariates (Age&sex) as a diagram. library(polycor) model.ly <-specify.model() 1: x -> m1, gam11, NA 2: x -> m2, gam12, NA 3: x -> m3, gam13, NA 4: age -> m1, gam14, NA 5: age -> m2, gam15, NA 6: age -> m3, gam16, NA 7: sex -> m1,

Hi all, I have a matrix simulating migration in a spatial model. I want to be able to define movement (the values of m1, m2 and m3) as only != 0 between adjacent patches and contingent on certain conditions as defined in the function. Here is the code: WET<-function(t) {everglades$precipitation[t]} #simply reads precipitation data from a csv, value is numeric AB<-function(WET,t)

Hi I have a small ISDN PABX , (BRI) at home - Siemens Gigaset 4175 which has cordless DECT extensions. I have set up asterisk on FC3 with two HFC cards and I am using the latest bristuff. I am trying to use * between my ISDN line and my PABX. One card is in TE mode and can receive and make calls OK. I can make and receive external calls to a SIP phone. I cannot get the other card to talk to my

Any ideas? Sangoma support is closed for the evening. I have the latest Sangoma drivers and Asterisk 1.4 everything installed. When I fire up asterisk, I keep getting "Primary D-Channel on span 1 up" repeated over and over. The B channels never come up. There are no errors in any of the logs, zttool, or the wanpipe tools. Intense pri debug output: < Unnumbered frame: < SAPI:

I have a question regarding significance testing for the difference in the ratio of means. The data consists of a control and a test group, each with and without treatment. I am interested in testing if the treatment has a significantly different effect (say, in terms of fold-activation) on the test group compared to the control. The form of the data with arbitrary n and not assuming equal

Simple matrix indexing suffices without any fancier functionality. ## First convert M and N to character vectors -- which they should have been in the first place! M <- sort(as.character(M[,1])) N <- sort(as.character(N[,1])) ## This could be a one-liner, but I'll split it up for clarity. res <-matrix(NA, length(M),length(N),dimnames = list(M,N)) res[as.matrix(C[,2:1])] <-
