I will have a job test with R two weeks later. I always have used Python for spatial analyses and I am so nervous..I hope I can pass it with your videos! :)
Files with .shp and associated extensions are vector data not raster data. Check out our video on getting started with vector data ua-cam.com/video/Cl-fyajKnmI/v-deo.html
You have to be able to install packages to do this sort of work. Most R installations will let you at least install packages to a personal library even if you don't have permission to install things more generally on the machine: wiki.uiowa.edu/display/hpcdocs/Adding+R+programs+to+a+personal+library
do you know if there is any prepared data that displays earths surface (just continents and oceans) in r?
very good video, i started with R and find your video is the most simple, and good example, easy to understand
Thanks! I’m really glad it’s helpful

I hope so too! Good luck!
the files I am working with doesn't have .tiff only shp and those extensions. What should I do?

Can you also do this with temperature data too? Is the process the same way?
Yes, everything would work the same way for temperature data
Thanks for the sharing this video. May i ask how if i cann't install the packages (stars, ggplot2). Thank U

There is no stars package available in Rstudio. My version is 4.3.3
Did you install the package? If not then run install.packages('stars') and you should be ready to go
Please do a video on satellite images using random forest algorithm on R
can you share the dataset you were using, please
I've added a data link and a couple of other relevant links to the description for the video. Let me know if you need anything else!
Vey clear explanations thank you so much!
You’re welcome!
how to download harv file
i mean practice file
There's a link to the data in the description.
@@weecology thank you
Thank for the sharing this important video. If possible share us how to aggregate gridded data of the different spatial resolutions.
You can do this using the st_warp function in stars. There's an example here: 132.72.155.230:3838/r/geometric-operations-with-rasters.html#resampling
So useful ! Thanks you so much !
You’re welcome!
thank you for this intrioduction
awesome ! greetings from brazil
Glad it's helpful! 👋
very useful, thank you
You're welcome!
there is no library called stars
You need to install it with install.packages()
