I'm trying to directly load a .jpeg image from a url address. I'm wondering if there is a basic way to do this by using a url
connection.
I first tried:
require(biOps)
con <- url("http://upload.wikimedia.org/wikipedia/commons/9/95/Apollonian_spheres.jpg")
pic <- readJpeg(con)
#Error in readJpeg(con) : Cannot open file.
This other question seems to be along the same lines, but for a .png file. I tried to adapt to a .jpeg, but also got an error.
require(biOps)
require(RCurl)
myurl <- "http://upload.wikimedia.org/wikipedia/commons/9/95/Apollonian_spheres.jpg"
pic <- readJpeg(getURLContent(myurl))
#Error in readJpeg(getURLContent(myurl)) : Cannot open file.
Any help would be greatly appreciated!
Just save the image as a temporary file:
myurl <- "http://upload.wikimedia.org/wikipedia/commons/9/95/Apollonian_spheres.jpg"
z <- tempfile()
download.file(myurl,z,mode="wb")
pic <- readJPEG(z)
file.remove(z) # cleanup
