Which are the recommended scripting languages for making graphics / pretty pictures in a Gnu/Unix
OS?
I would like to create 2-d and 3-d objects fast along with different things like shading them..
Does Python offer any support for doing such things?

There are OpenGL bindings for python, lua and ruby (and for nearly every other language). If you want to go with python, there are libraries like Panda3D, Soya3D
and OGRE (which by the way has also bindings for e.g. Perl, Ruby and others).

What were the design decisions that led to R having often more than one way of doing things, that have subtle difference? See, for a good example,
https://www.r-bloggers.com/r-na-vs-null/
More more such issues are here, some which are justified, some which are not http://r4stats.com/articles/why-r-is-hard-to-learn/
From a software engineering perspective, having such choices in a language screams for having subtle and hard-to-find bugs in your code (e.g. in Python the whole point of writing "pythonic" code, that avoids ambiguity and is easy to read and consistent in style). So there must be some major advantages of having that. What are they?

I am trying to do tagging of a french text, but TreeTagger needs Python which is impossible to install on my PC at work. For security reasons, it is impossible to install other programs (only R).
Is it possible to use R code for tagging which does not require neither java nor Python?
At this moment there are no French POS-taggers implemented in R.

I am well aware this is a crazy thing to ask, but what method and or language should I look towards to work with numbers of over 1*10^100000000? I know doubles and such have much smaller limits in accuracy, but my purpose is to apply math such as division, addition, etc to these numbers.
Different languages use different library to support arbritrary-precision arithmetics. Most modern programming language offer support for it in one way or another.
Take a look at: http://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic#Languages
What you are looking for is called arbitrary-precision arithmetic. Typically there are separate packages for integers and for floats. Some languages have these built-in; for example Maxima [1] has both integers and floats. Some other languages (e.g. Common Lisp) have only integers built-in. For other languages such as C and C++, you can get libraries.

I would like to find a library for parsing and generating text in common lisp. I would like it to be maintained and documented and preferably with a community that could answer questions.
In the past I have used for the same job ANTLR/StringTemplate in Java and Boost.Spirit in C++. Both projects are well documented in my opinion. From what I am reading, Parsec for Haskell would also meet my requirements. But I have not found something similar for LISP. Perhaps lispers parse texts using their own hand-made parsers?
I am aware of this question, but the so-called documentation on smug is a technical report on monadic parsing, with examples in Haskell. The documentation of LispBuilder looks rather short also. Most projects in CLiki seem abandoned.
Which library would you recommend? The grammar I need to parse is not very complicated.

Syntactically, at least, SQL is pretty far off. Thanks!
Dataphor's D4 is said to be pretty close (sole major error being the introduction of a null-like construct that the customers forced upon the developers, IIRC).
The projects listed on The Third Manifesto's project page ( http://www.dcs.warwick.ac.uk/~hugh/TTM/Projects.html ) should all be expected to abide even more closely.
There are the two syntactically very different languages: Relational Algebra and Relational Calculus, and SQL is a mixture of both. There are plenty of verbatim Relational Algebra implementations, so the matter obviously is not how "faithful" the implementation is.
