Detailed description

<I'm pretty new to R programming, so I'm sorry if my question is relatively dumb. I have ROpenCVLite installed and have gone through the long process to install OpenCV. Once I try to install trackR, I run into the following error:

Any insight onto why OpenCV isn't registering as installed? I get the same issue when I try to install just Rvision. Thanks for your time!>

@goldenbrowntoast It looks like you're using an old R version. Can you try with the latest version?

Haha, yeah, this got me through that error. I can't believe I didn't notice the "Rvision for 3.5". Sorry about that.
