Hello  all  R   users,
My simulation function works correctly, but I have problems with plot
function. You will find the following code using it.
Thank you for your help
##################################################"

simulation <- function(k, n){

conc <- seq(0,10,by=0.5)
#choixg <- seq(1, length(conc))
choixg <- rep(0,length(conc))
for (i in 1:length(conc)){
    choixg[i] <- (k + conc[i])^2/((k+conc[i])^n + (k+1)^n)

    }
   return(choixg)

}
simulation(5,1)

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