[R] repeating matrices in a list

Suppose I have the following square, non-negative matrices > g=matrix(c(0,2,4,0.25,0,0,0,0.6,0),3,3,byrow=T); I want to create a list where this matrix is repeated multiple times. if I do this brute force (manually), using > env <- list(g,g,g) works fine. Yields [[1]] [,1] [,2] [,3] [1

[R] newbie: embeding seq in a list

Suppose I want to create a structure containing the following values: 0.8,0.9,1.0,1.1,1.2 If I use env <- list(0.8,0.9,1.0,1.1,1.2) then R returns > env [[1]] [1] 0.8 [[2]] [1] 0.9 [[3]] [1] 1 [[4]] [1] 1.1 [[5]] [1] 1.2 But, if I try to 'save some key-strokes', and use env <- list(seq(

[R] cbind, data.frame | numeric to string?

Complete newbie to R -- struggling with something which should be pretty basic. Trying to create a simple data set (which I gather R refers to as a data.frame). So > a <- c(1,2,3,4,5); > b <- c(0.3,0.4,0.5,0,6,0.7); Stick the two together into a data frame (call test) using cbind > test <- dat
