r - 遍历列

Question

我正在尝试遍历列并使用以下代码计算以下数据集的卡方检验

result=numeric(length(client-1))
for (i in 1:length(client-1)) {
result=chisq.test(table(client[[i]], client[[i+1]]))
}

我的数据集样本在这里

       sex                mar_st                                    education

7      h) Unemployed                     
8      h) Unemployed  

我收到以下错误/警告...

 #Error in .subset2(x, i, exact = exact) : subscript out of bounds
 #In addition: Warning messages:
 #1: In Ops.factor(left, right) : - not meaningful for factors

有人可以帮忙吗

在我看来，这就是你想要做的：

result=numeric(length(client)-1)
for (i in 1:(length(client)-1)) {
  chi <- chisq.test(table(client[[i]], client[[i+1]]))
  result[i] <- chi[["statistic"]]
}
result
