r - IDL 中的 LINFIT 如何在 R 中表示？

Question

我有一个用 IDL 编写的代码，我想将其转换为 R。

在代码中我发现了这个函数：

result  = linfit(dum_x, dum_y) 
 y_a= result[0]
 y_b= result[1]
           "LINFIT function" which fits the paired data { xi , yi } to the linear model, y = A + Bx, 
               by minimizing the Chi-square error statistic

我想知道R中是否有类似的功能？任何想法我们如何将此行转换为 R ：

       y_a= result[0]   

Answer 1

My guess is

result <- lm(dum_y~dum_x)
y_a <- coef(result)[1]
y_b <- coef(result)[2]

but I don't have access to IDL so I can't check ... you could give a reproducible example with IDL/LINFIT results ...
