Please read the manuals!
The objects "conc" and "choixg" ar local to your function "simulation"...

If you return

   return(list(choixg=choixg, conc=conc))

from your function, then you can plot as follows:

   simResult <- simulation(5,1)

   with(simResult,

     plot(conc, choixg, main ="fonction de choix",
       col= "blue", pch=20, xlab = " concentration",
       ylab="proba de choisir la gauche"))
