This recipe helps you read images in R

Recipe Objective

How to read images in R? There are various libraries that can read an image in R such as the ImageMick, imager, jpeg, etc. All these libraries are used for reading and manipulating images in the R environment. The imagemick and imager support many types of image formats like.jpeg,.png,.tiff etc. This recipe demonstrates an example of how to read an image in R.

Step 1 - Install necessary package

install.packages('magick') library(magick)

Step 2 - Reading the image

image <- image_read("https://upload.wikimedia.org/wikipedia/commons/thumb/8/8e/2017%2C_cuba%2C_jardines_aggressor%2C_los_indios%2C_nassau_grouper_maw_%2836883128693%29.jpg/150px-2017%2C_cuba%2C_jardines_aggressor%2C_los_indios%2C_nassau_grouper_maw_%2836883128693%29.jpg")

Step 3 - Using the imager package

install.packages('imager') library(imager) file_path <- system.file('extdata/Leonardo_Birds.jpg',package='imager') im <- load.image(fpath) plot(im) {"mode":"full","isActive":false}
