R for analysis of rasters/PC?

I’ve read about R and I am going to explore that.

As I’ve read it can be used for analysis and some editing. Even using AI is possible m.

Anyone here with experience with R?

Yup! Not an expert but a help at times for the occasional R problem. :ocean:

What have you done with R? Any tips on how hat to look for.

Start with the tidyverse: https://www.tidyverse.org/, not because it’s the right way to do R, but because it’s a consistent way to do R.

I have a few blog posts, mostly on gorillas and golden monkeys where I used R: smathermather.com

Some package on pointclouds?

I would recommend checking out a GUI like R-Studio, especially when getting started. Helps lower the barrier to entry.

Do you use R also?

Very, very poorly, yes.

I mostly use it via the R processing toolbox in QGIS now.

A former student I TAd has an incredible blog on how she uses R that I’ve been trying to find for you :grimacing:

Boom:

She was incredible with R. Went from never using it to basically an expert within a Quarter. I had nothing to do with that :rofl:

I’ve installed R for QGis but I can’t seem to download the charred package of algorithms.

It seems so be a lot of pointcloud packages and I hope to learn some neural network stuff.

My biggest problem with programming isn’t really learning stuff, it’s finding a use for it and finding the time to make something.

I used R when I wrote my master’s thesis, and while I enjoyed working with R more than Excel I get the feeling that it probably wouldn’t be something I could jump back into five years later.

Good stuff, though, and I look forward to seeing how it could be used in this environment!

Started testing to learn the basics.

I failed making a function with a FOR loop that should result in a new list.

I was fairly proficient before I decided to figure everything out in python now ( which so far, I’ve found to be possible). I think you’ll find the statistical analysis packages slightly more robust than python’s. Here’s a book I helped my Professor with - Introduction to Environmental Data Science. There’s a women from NUSO who’s done some cool stuff with lidar point clouds. I’ll dig around for her code.

Going forward…

Tried for loops, nested for loops, plot, apply, %>% and reading in files as CSV and LAZ…

I find it strangely easy to do things. Even though R isn’t very fast it makes up for it in ease off use.

Haven’t done anything productive though, hopefully I find something. Any tips and tricks that you can give is appreciated.

Just learned there’s something called “tidy data”.
