How to create a list of matrix in R
Try
x <- matrix(1:10, ncol=2)y <- x+300MATS <- list(x, y) # use 'list' instead of 'c' to create a list of matricesMATS[[1]] [,1] [,2][1,] 1 6[2,] 2 7[3,] 3 8[4,] 4 9[5,] 5 10[[2]] [,1] [,2][1,] 301 306[2,] 302 307[3,] 303 308[4,] 304 309[5,] 305 310Here you have to refer to MATS[[1]] as if it were x
If you want to append a new matrix to the exiting list try
z <- x+500MATS[[3]] <- z # appeding a new matrix to the existing listMATS[[1]] [,1] [,2][1,] 1 6[2,] 2 7[3,] 3 8[4,] 4 9[5,] 5 10[[2]] [,1] [,2][1,] 301 306[2,] 302 307[3,] 303 308[4,] 304 309[5,] 305 310[[3]] [,1] [,2][1,] 501 506[2,] 502 507[3,] 503 508[4,] 504 509[5,] 505 510One drawback of this approach is that you have to know the position in the list where you have to append the new matrix, if you don't know it or simply if you dont want this approach, then here's a trick:
unlist(list(MATS, list(z)), recursive=FALSE) # will give u the same list :D
