How to use the ‘while’ statement to find the maximum value in R language.

In R language, the while statement can be used to find the maximum value in a vector. Here is an example code:

# 创建一个向量
vec <- c(10, 5, 2, 7, 15, 3)

# 初始化最大值为向量的第一个元素
max_value <- vec[1]

# 使用while循环遍历向量
i <- 2
while(i <= length(vec)){
  # 如果当前元素大于最大值，则更新最大值
  if(vec[i] > max_value){
    max_value <- vec[i]
  }
  
  # 更新计数器
  i <- i + 1
}

# 输出最大值
print(max_value)

The code first creates a vector, then initializes the maximum value as the first element of the vector. Next, it uses a while loop to traverse the vector, comparing starting from the second element. If the current element is greater than the maximum value, it updates the maximum value. Finally, it outputs the maximum value. In this example, the output result is 15, which is the maximum value in the vector.
