Chi squared for three different vectors of unequal sample size

I am looking to perform chi-squared on three different vectors which have an unequal sample size.

I have tried to do this as both vectors and combing the data in a dataframe but continue to get error messages including "x" and "y" must have the same length.

I have put some example vectors below / how I have combined into dataframe.

alpha <- c(10,15,20)
bravo <- c(12,18,19,20)
charlie <-c(19,30,21,34,10)

> chisq.test(alpha, bravo, charlie)
Error in chisq.test(alpha, bravo, charlie) : 
  'x' and 'y' must have the same length

max_ln1 <- max(c(length(alpha), length(bravo)))
max_ln2 <- max(c(length(charlie))) 
max_ln<-max(max_ln2,max_ln1) 
df_fem<- data.frame(total = c(alpha,rep(NA, max_ln - length(alpha))), 
                    af = c(bravo,rep(NA, max_ln - length(bravo))), 
                    naive = c(charlie,rep(NA, max_ln - length(charlie))))
