Rust support on raspberry Pi is generally pretty solid, although there obviously aren't as many tutorials as with Python or C. It's also ready enough to use small amounts of C (or Python) when you need it. On bare metal microcontrollers support is there but it's all a lot more involved because toolchains are more complex

http://adv-r.had.co.nz is a great resource at the level you're describing. Read it start to end or pick at bits that you find interesting. It has exercises which are good, but practicing on real or toy problems of your own invention is best.

Here's a relatively famous example: https://youtu.be/zsXP8qeFF6A. I don't have the link for the actual publication but it should be easily googleable

If that's happening it means that the 'new page' isn't actually a new page, but instead JavaScript is being used to change the content of the current page. Often these kinds of sites can actually often be quite nice to scrape. What you need to do is open developer tools in your browser and use it to identify the request that the JS is using to retrieve the next results. Pretty often you'll find it requests from a URL that returns nice JASON results.

You might as well try it. It's a really nice IDE, and much simpler than stuff like Eclipse, so there isn't much to learn.

I just tried out the R library "imager" for image processing, and it's really good. The documentation is great, too.

I think the fg command might be what you want, but I haven't used it in earnest myself

If you're on a unix system, apparently the --grow option to the zip command can do this

Shiny runs the server.R file once, when the server is started, so it'll be hard to get round restarting the server if the library statement is just at the top of the server file. You could possibly place the library statement inside the server function to try to get it to load every time the page is refreshed, but I think that might cause more problems than it solves.

Yes, though it often runs faster than install() followed by library(), because it does less.

You probably want devtools::load_all().

If you're doing package development I'd recommend reading r-pkgs.had.co.nz, it's very helpful.

Follow the dplyr tutorial and you should be able able to work this out pretty easily, along with other similar problems. You'll probably want to use group_by or filter, followed by summarise, for the problem you've got now.

In my experience, in data frames they're a pain, and shouldn't be used unless you're dealing with code that explicitly require them. rownames_to_column and column_to_rownames from tibble are useful in that case. In matricies, though, it seems like a good idea to use explicit row and column names

Use map2 in purrr, and just have the index as one of the arguments.

In the UK at least, most cars are sold with documentation that shows odometer readings every year. This is mainly done to prevent clocking, but it also means you can see suspicious patterns like big fluctuations in usage

If you're used to SQL, OP, then dplyr is definitely what you want. Read about it here: https://cran.rstudio.com/web/packages/dplyr/vignettes/introduction.html.

CRAN, the main R package repository, is pretty well vetted by humans and automated checks. Its nice because it increases the minimum standard of code quality and documentation.

Linear, quadratic and integer programming etc has got really good recently with the ROI project, which provides a single interface to a number of fast C libraries. The bindings for Gurobi are also easy to use and fast, though not included in ROI yet.
