Question

我想在循环中运行一个函数，其中输入数据来自具有连续数字的列表，如下所示：

output <-create_list(input) %% function that creates the list

输出具有M1，N1，M2，N2，M3，N3，M4和N4

for (i in 1:4) {

  m <- output$M[i] %% This is wrong but is a good way to show my aim
  n <- output$N[i]  
  output2<- fiting(m,n) %% target function 
}

Answer 1

尝试：

# You want to keep the fits you generate, a list can hold everything
fits <- list()

# This generates a sequence that increments be two:
# i.e: 1, 3, 5, 7 etc, it won't generate any value greater
# than the maximum value (defined by length(output))
for(i in seq(1, length(output), by = 2))

  # Then just run the fitting function on each two values
  fits <- c(fits, fitting(output[[i]], output[[i + 1]]))

# Fits then contains a list of outputs

使用存储在列表中的矩阵循环
