At the moment, I try to learn automation of graphic drawing with latex (tikz) and R.
I need to determine the coordinates of the point with the smallest distance to a defined point "North"
Thats what I found out so far:
Code: Select all
\begin{tikzpicture}
\coordinate (North) at (0,5);
\path let
\p1 = ($(North)-(node_1)$), \n1 = {veclen(\x1,\y1)}
, \p2 = ($(North)-(node_2)$), \n2 = {veclen(\x2,\y2)}
, \p3 = ($(North)-(node_3)$), \n3 = {veclen(\x3,\y3)}
, \p4 = ($(North)-(node_4)$), \n4 = {veclen(\x4,\y4)}
in coordinate (dummy1) at (\x1, \y1)
coordinate (dummy2) at (\x2, \y2)
coordinate (dummy3) at (\x3, \y3)
coordinate (dummy4) at (\x4, \y4);
\end{tikzpicture}My basic idea was to implement something like an if loop:
if \n1 == min(n1, \n2, \n3,\n4) then coordinate (nearest_to_north) at (node_1)
elseif \n2 == min(n1, \n2, \n3,\n4) then coordinate (nearest_to_north) at (node_2)
elseif...
The whole Latex-codes is embedded in an *.Rnw-File so it would also be possibel to implement the loop in R-code but I also dont understand how to transfair the latex commands \n1, \x1, \y1 to R.
The tikz syntax is very confusing to me...so Im looking forward to any suggestions or help
...I also asked this question here in German: https://golatex.de/viewtopic,p,106794.html#106794
