similar to: rearrange set of items randomly

Hi, can anyone tell me if R can be used to rearrange very complicated equations in terms of one of the variables? I have: dx/dt = a*b*m*y*(1-x)-r*x and, having set: dy/dx = 0, need to rearrange in terms of x. The problem I have is that I don't know how to rearrange equations when the variables are not yet defined (I get messages warning me that x etc can't be found). I'm not sure

Hello again. If you recall, I am the guy working on enabling Audacity to losslessly rearrange Ogg Vorbis files for my senior thesis. I have more or less completed the required modifications to Audacity to support this. You can read more about the work this entailed by reading my journal: http://www.reverberate.org/computers/thesis/journal Now my attention moves to the Ogg Vorbis code

Hi All, I am trying to rearrange alphabetically each element in a character vector. ex: say the first element in the vector is "cba", and my goal is to turn it into "abc". The suggested function to use is sort(). But it turns out that sort doesn't work at the level of element. So I am wondering that if there is an alternative function for this purpose. Please help me out .

Dear all, I have received some data arranged like this: # original data id <- rep(letters[1:6], each=2) time <- as.factor(rep(1:2, 6)) y <- as.vector(replicate(6, c(rnorm(n=1, mean=1), rnorm(n=1, mean=2)))) test.data <- data.frame(id, time, y) test.data I would like to perform a paired t-test of the y-values at time=1 against those at time=2, with samples paired by their id. Is it

Hi all, I'd appreciate if anyone can help me with this...

Dear all, I am currently working on a function in which I would like to avoid using the command sample(). Therefore, I am now trying to make a for loop that does the same thing as the in built function sample does: Rearranging the items of a object randomly. So, the output I want to you get is the same as sample() would give me: e.g.: data <- c(5,4,6,7,8) sample(data) > data <-

Hi, Please apologize if my questions sounds somewhat 'stupid' to the trained and experienced statisticians of you. Also I am not sure if I used all terms correctly, if not then corrections are welcome. I have asked myself the following question regarding bootstrapping in regression: Say for whatever reason one does not want to take the p-values for regression coefficients from the

My question arises when I use levelplot graphics. For example, levelplot(z~x*y|fg) where fg is a factor with three levels of 'a','b','c'. The panels come out in a default order. I would like to rearrange the panels in a manner of 'c','b','a'. I used fg<-ordered(fg, levels=c('c','b','a')) But the panels are still the

I have a matrix, called data. I used the code below to rearrange the data such that the first column remains the same, but the y value falls under either columns 2, 3 or 4, depending on the value of z. If z=1 for example, then the value of y will fall under column 2, if z=2, the value of y falls under column 3, and so on. data x y z [1,] 50 13 1 [2,] 14 8 2 [3,] 3 7 3 [4,] 4 16 1 [5,] 6
