【问题描述】：

我想在一个 while 循环中按顺序附加我的数据，以便在每次迭代后我都会将前一个值附加到新值，例如：

i = 0
predictor = "test"
while(i < 7){
  i = i+1
  form1 <- append('test', i)
  print(form1)
  
}

[1] "test" "1"   
[1] "test" "2"   
[1] "test" "3"   
[1] "test" "4"   
[1] "test" "5"   
[1] "test" "6"   
[1] "test" "7"

预期输出：

[1] "test" "1"   
[1] "test" "1" "2"   
[1] "test" "1" "2" "3"   
[1] "test" "1" "2" "3" "4"   
[1] "test" "1" "2" "3" "4" "5"   
[1] "test" "1" "2" "3" "4" "5" "6"   
[1] "test" "1" "2" "3" "4" "5" "6" "7"

【问题讨论】：

将您的 form1 更改为 predictor <- c(predictor, i)
