"Not that it really matters, but" Can someone explain how the row numbers get assigned in the following sequence? It looks like something funky happens when rbind() coerces 'bar' into a dataframe. In either sequence of rbind below, once you get past the first two rows, the row numbers count normally. Rgames> (foo<-data.frame(x=5,y=4,r=3)) x y r 1 5 4 3 Rgames>

I would like to selectively remove rows from a table. I had hoped that I could create a table and selectively add rows with something like > NewTable<-table(nrow=100, ncol=4) > NewTable[1,]<-OldTable[10,] but that doesn't work. The former call gives > NewTable ncol nrow 4 100 1 while the latter call gives a table the length of OldTable. Making a matrix, m, with the

I'm using functions to return a matrix of all permutations of a specified size from a larger list for predictor selection. For each predictor size I use a seperate function like this: bag2 <- function(n) { rl <- c() for (i1 in seq(n)) { for (i2 in seq(n)) { if (length(unique(c(i1,i2)))==1) {next} rl <- cbind(rl,matrix(c(i1,i2))) } }

Hi, Here's the problem I ran into: the gmp package has a method for apply() so it masks the base::apply function. With gmp installed, I tried to run the function turnpoints() from the pastecs package. It fails because it calls apply() internally, like this: apply(mymatrix,1,max,na.rm=TRUE) , but the code in the gmp package which sets up the operator overload for apply() strictly

Hi, Suppose I have the following data name     score Abel        88 Baker      54 Charlie    77 stored a  table called myData. I want to write a function that will create a table which is a subset of myData containing those have a score > 75. I know I can do this with the following command: subset(myData, score > 75) But I would like to do this via a function, something like:

Hi all, This should be easy, but I can't seem to figure it out. I have a table like this named newtable a1 a2 a3 a4 Cnts Score 1 1 0 0 4 3.28 1 0 1 1 2 2.63 I want the following: a1 a2 a3 a4 Cnts Score 1 1 0 0 4 3.28 1 1 0 0 4 3.28 1 1 0 0 4 3.28 1 1 0 0

Here's my contribution to R. When R interacts with external programs (MySQL, cURL, etc.), it often requires a pasted string that is sent to these programs. For readability reasons, it is often preferable to have complex commands (SQL for example) spread on several lines. However, the normal paste function requires to add additional ' ", ' at the end of each line and another '

Dear R users, First of all sorry for this question, surely quite naive. (I searched on the R site but was unable to find by myself). I have a table, called infile : 1 2 3 4 5 6 7 8 9 I would like to read it and ignore the rows with 1st element > 3 I do it now with a for loop, and it's ok, but I was expecting something simpler, like : intable = read.table(infile); newtable =

I have a Newbee question: i have three tables and want to connect them. so is it stupid to make a triple m:n (rails style xs_ys_zs) or do i have to make a new table (newtable) where i got multiple 1:n? the habtm (has and belongs to many) do only work proper to join two tables, or i am wrong? -jens -- Posted via http://www.ruby-forum.com/.

Hi all, I'm working with a bunch of large graphs, and stumbled across something useful. Probably many of you know this, but I didn't and so others might benefit. Using pch="." speeds up plotting considerably over using symbols. > x <- runif(1000000) > y <- runif(1000000) > system.time(plot(x, y, pch=".")) user system elapsed 1.042 0.030 1.077

Dear list, I have been struggling for some time now with this code... I have this vector of unique ID "EID" of length 821 extracted from one of my dataframe (skate). It looks like this: > head(skate$EID) [1] "896-19" "895-8" "899-1" "899-5" "899-8" "895-7" I would like to remove the complete rows in another dataframe

Hello, everybody! I have a matrix "input" (see example below) - with all unique entries that are actually unique ranks (i.e., start with 1, no ties). I want to assign a value of 100 to the first row of the column that contains the minimum (i.e., value of 1). Then, I want to assign a value of 100 to the second row of the column that contains the value of 2, etc. The results I am looking

Hi, i am unable to install the rugarch package. More than that i do not even find this package in my list of possible packages. Its possible than the name has changed, or the package is not longer availiable? Is there a similar package avaliable for garch modelling except the fGarch what i am using now? many Thanks Roland -- View this message in context:

Is it possible to create a database in MySQL via RMySQL? Also, is the format for the authorization field 'userName/password at databasename'? I saw an example like this somewhere in the documenation, but I haven't found the actual specification. Thanks, Barnet Wagman

Hello all, I''ve got a site that will be used by people (hopefully) all over the world. One of the requirements of registration is country and province of residence.
