Hi, 

You can read the image using Magick package as below.

library(magick)
img = image_read("C:\\Users\\Cherukuri_Sindhu\\Downloads\\teams.jpg")

To resize the image, use image_scale() function.

img_scale = image_scale(img, "[Value]")  #for resizing width

img_scale = image_scale(img, "[xValue]")  #for resizing height

To resize both height and width, try below code - 

image_scale(image_scale(img,"[Value]"),"x[value]")

where value is either relative to parent object or fixed size values.

Value = 100% or 500 or 200%, etc.
