I want to create an RGB image from three 2D matrices in R. I know there was a similar record for matlab , however I could not translate this problem for world R.
I tried different packages already, such as abind to create a 3D array, tried to turn it into JPEG using writeJPEG. but it didn’t work -
any help is much appreciated!
Try with ?rgb ,
?rgb
r <- matrix(runif(9, 0, 1), 3) g <- matrix(runif(9, 0, 1), 3) b <- matrix(runif(9, 0, 1), 3) col <- rgb(r, g, b) dim(col) <- dim(r) library(grid) grid.raster(col, interpolate=FALSE)
