如何从R中的三个矩阵创建RGB图像？

I want to create an RGB image from three 2D matrices in R. I know that there was a similar post for matlab, however I could not translate that problem to the R world.

我想从R中的三个2D矩阵创建一个RGB图像。我知道matlab有一个类似的帖子,但是我无法将这个问题转换为R世界。

I tried already different packages such as abind for creating a 3D array, tried to turn it into a JPEG with writeJPEG. but that did not work-

我尝试了不同的软件包,例如用于创建3D数组的abind,尝试将其转换为带有writeJPEG的JPEG。但那不起作用 -

any help is very much appreciated!

很感谢任何形式的帮助!

Try with ?rgb,

尝试使用?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)
