Join Mark Niemann-Ross for an in-depth discussion in this video Overview of my solution, part of Code Clinic: R (2015).
- Like all problems, this solution will be easier…if we break it down into parts.…After reading the problem description,…I found three parts.…First, Search the directories for images.…Second, Find the image data for those images.…And third, use that image data…to then Sort the images into directories.…If you look at the readFileinfo.R file,…which is located in the Exercise Files,…you'll see how I've broken this up into steps.…I made a note in line 3 and 4…that you'll require ImageMagick.…
We'll talk about that in a second.…Starting at line 8, you can see…that I'm searching for images.…Starting at line 29, is where I look…for the image data.…And then starting at line 43,…is where I use that image data…to sort things out into directories.…Again, it's all fairly straightforward.…We'll talk about this in a second.…This solution is dependent on ImageMagick,…so let's take a quick look at that external library.…
Mark introduces challenges and then provides an overview of his solutions in R. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.

Q: R Studio tells me that it can't find files I expect to be available. Where can I find them?
A: Use the setwd() command to set the working directory to match the folder you're working in.
Q: I am unable to access the Lake Pend Oreille data from outside the U.S.
