I am reading Google's R Style Guide. It said:
When indenting your code, use two spaces. Never use tabs or mix tabs and spaces.
I use R Studio to program and feel it is very convenient and beautiful to use tabs. Other programming languages also use tabs for indentation.
I don't know why Google's R Style Guide does not recommend use tabs but two blanks.

You will notice if you check the options in Rstudio under code editing there is a choice for replacing tabs with a defined number of spaces. If you select this (which is set as default, with width = 2), then your tabs will be replaced automatically.

WHAT I'm trying to do:
What resources are there to learn about building Single Page Application's?
WHAT I've already tried:
Looking into, react, vue and angular's spa-routers, but they were super confusing and hard to use. I want something simple
For me the best option ended up being building my own router using jquery, like the following pseudocode:
on hash change:
get window.location.hash + '.html'
document.body.appendChild (response)
This allowed me to understand how the single page application worked and split my code into separate HTML files which I needed for organization and simplicity.

Is it possible to add a slider in R that can change certain values which are visualized?
For a project I want to make a suitability map with a certain amount of layers. The user of the map should be able to change the weights that the different layers contribute to the suitability.
After some research I found that this is possible in javascript, however I never used javascript.
This should be achievable with shiny.
Your question is too open-ended.

I have used both Foundation and Bootstrap, but I realised that the thing I only use it the grid.
I haven't had any problems with their grids, and don't really have a preference yet.
My question is, is it worth keep using them or is it better to use a framework that only has a grid system?
I prefer SASS over LESS
I'd keep using Bootstrap in case you ever want to borrow a bit of its functionality but don't want Bootstrap clashing with some other grid system's code.
If you don't want any of Bootstrap's extra styling muddling your design, follow these instructions to load only the grid from Bootstrap. Then, if you decide you need a quick dropdown navbar, just import the bits of Bootstrap you need.

While moving on web I found normlize.css can be used to persist the css effect in various browser.
http://necolas.github.io/normalize.css/2.1.3/normalize.css
There are two approach to use it:
Approach 1: use normalize.css as a starting point for your own project’s base CSS, customising the values to match the design’s requirements.
Approach 2: include normalize.css untouched and build upon it, overriding the defaults later in your CSS if necessary.
I think 2nd is easy.
Does it mean including this css untouched and then working with our css in normal way, correct?

I am looking for some help regarding documenting code in Qt. For instance, when I am developing on the XNA platform I use XML notation with tags such as summary, params, etc. What does Qt have and what are some standards.
In addition, I am looking for something that will work with documentation generating applications (such as Doxygen), unless Qt has something better that I don't know about.
Qt internally uses QDoc, which is not a supported product. It is similar to doxygen. If you already know doxygen, you should use it to document your Qt projects. See also this question.
