Not ready for production. Try at your own risks.

with functions to read and manipulate video and image files, as well as camera
streams.
Read the FAQ below for more info about the what, why, and how of
Rvision.
2 - Package installation
2.1 - Before installing
Before installing Rvision, you will need to install the latest version of the
devtools package in R.You can install devtools as follows:
install.package("devtools")2.2 - Installing Rvision
You can install Rvision as follows:
devtools::install_github("swarm-lab/Rvision")Rvision depends on ROpenCVLite to access OpenCV's functionalities. If not
already installed, ROpenCVLite will be installed first by the above command
line. This may take some time as it will download, compile and install OpenCV
for you (compilation time will depend on your computer). I suggest going out for
a cup of tea or coffee while ROpenCVLite is installing ;-)
3 - FAQ
Can I take pictures of my cat using Rvision?
Heck yeah! You can AND you should! You can even take pictures of your dog if you are that kind of degenerate person :-)
After placing your favorite pet in front of the webcam, just do:
my_stream <- stream(0) # 0 will start your default webcam in general.
my_pet_pic <- readNext(my_stream)
plot(my_pet_pic)
release(my_stream)Can I take selfies with my webcam using Rvision?
You certainly can, but you should ask yourself whether you should...
my_stream <- stream(0) # 0 will start your default webcam in general.
my_selfie <- readNext(my_stream)
plot(my_selfie)
release(my_stream)Be careful, this will trigger the explosion of your camera if it detects that you are making a duck face ;-)
