I have collected experience with TeX for quite some time and I am familiar with TeX programming. I have written pgfplots and several contributions to pgf/TikZ.

comment Parametric plot using pgfplots package
Good answer! Note that ` \pgfmathdeclarefunction{R}{2}{\pgfmathparse{#2 * (sinh(#1) - #1)}}` and \pgfmathdeclarefunction{P}{2}{\pgfmathparse{#2 * (sinh(#1) - 8*sinh(#1/2) + 3*#1)/3}} would also do the job - the PGF math engine can compute it with good precision.

comment Error in compiling with Tikz Externalize
Note that since pgfplots 1.11, the driver selection for image externalization has been improved. A document compiled with lualatex will automatically translate externalized images with lualatex as well.

comment pgfplots - plusminus doesn't match its definition
Sometimes packages modify characters such that they do stuff ("become active"). You might help us to identify if this is the root cause by adding \catcode\-=12 somewhere before the offending plot (or the offending figure). This will restore the character handling for -. If this is the case, we have to identify the package which redefined the -` char.

comment Help to draw an arbitrary surface with in TikZ
The linked question covers "simple" surfaces. Sometimes one needs more complicated surface as known from plot tools. For such advanced surfaces see tex.stackexchange.com/questions/31708/… and tex.stackexchange.com/questions/99133/…

comment How to plot following graph
You are welcome. My best wishes for your thesis! Regarding the interaction of pgfplots and lualatex: lualatex can be considered as a way to avoid memory restrictions (often needed) or to avoid numerical inaccuracies (almost never necessary). For all other cases, you do not need it. This holds for all versions of pgfplots up to and including 1.10 (the current stable).

comment How to plot following graph
Good answer! Just for the records: note that you do not need lualatex here - it is sufficient to use \addplot [solid, thick] {x^2}; and \addplot [dashed, thick] {x^3};, respectively.

revised draw direction cosines using tikz
removing pgfplots tag as this is more about tikz-3dplot

comment Black Fill in my plot
So the tikz picture compiles with lualatex and/or pdflatex, right? In this case it is a driver problem.

comment Rotation transformation of a parametrized plot
You should consider the additional options shader=flat, miter limit=1. The fine grid lines result in a relatively hard look which is smoothened by shader=flat, and miter limit` avoids the tiny overshoots near edges.

comment Black Fill in my plot
Some time ago, I stumbled about the same - until Till Tantau pointed out that I have used a driver (dvipdfm, I suppose) for which these patterns were not implemented at that time. Can you tell us how you compile the file? And: does the errors persist if you try it with pdflatex?

revised How do I get a straight line in \begin{tikzpicture}[decoration=Koch snowflake]?
removed pgfplots tag since the problem is unrelated to the add-on package pgfplots

I edited the post to explain that stuff; hopefully it clarifies the items.
