What is the easiest way to display a bitmap in R?

I work with TIFF images in R. I load images as

library(tiff) img <- readTIFF("someimage.tiff")

I am manipulating an img array and want to see the results. One option is to use the writeTIFF function to store the image on disk and open it using the image viewer. However, I want to have an easy way to display images inside R. What would you recommend?

here is one option:

 img <- readTIFF(system.file("img", "Rlogo.tiff", package="tiff")) grid::grid.raster(img)

You can do:

 library(raster) b <- brick("someimage.tiff") plotRGB(b)

If you read in tiff as your own raster, you can use the rasterImage() function.

  img = readTIFF('someimage.tiff', native=TRUE) plot(NA,xlim=c(0,nrow(img)),ylim=c(0,ncol(img))) rasterImage(img,0,0,nrow(img),ncol(img))

This method works similarly for functions (and corresponding packages): readJPEG, readTIFF, etc.
