Re: [R] Odd behaviour of identical()

Thanks. I was not aware of these subtleties of R, but then again I'm no expert. I had to use isTRUE(all.equal(vec,c(0,0))), but it seems to be working now. Thanks again. -- View this message in context: http://r.789695.n4.nabble.com/Odd-behaviour-of-identical-tp4630118p4630170.html Sent from t

[R] Odd behaviour of identical()

Consider the following code: test <- function(n) { for(x in 1:n) { for(y in 1:n) { for(r in max(x-1,1):min(x+1,n)) { for(s in max(y-1,1):min(y+1,n)) { vec <- c(x-r,y-s) print(c("vec = ", vec)) print(identical(vec,c(0,0)))

[R] How to apply a function to a multidimensional array based on its indices

Hello. I have a 4 dimensional array and I want to fill in the slots with values which are a function of the inputs. Through searching the forums here I found that the function "outer" is helpful for 2x2 matrices but cannot be applied to general multidimensional arrays. Is there anything which can a

[R] problems with plot()

I have a list of vectors of length 2, each representing a point in 2-space, and each of which I wish to plot on the current plot. In a loop, I assign the x and y coordinates of the current element of the list to variables 'x' and 'y' respectively, then make a call to plot as follows: par(new = T

[R] Odd subsetting behaviour

Hello. I've observed some odd behaviour. Most likely, it is already known and explained somewhere, but I can't find an explanation anywhere, so I would appreciate being pointed in the right direction. The issue with the following code is self explanatory: > mat <- matrix(c(c(1,1,1),c(2,2,2)),nro

[R] retrieving last R output

Hello. I ran a simulation that took a few days to complete, and want to analyze the results, but have just realized that I (idiotically) did not assign the output to a variable when I intitiated the simulation. Is there any way to retrieve the last output produced by R so that these last few days
