更改内置函数中的默认值 [英] Change the default value in a built-in function

问题描述

我想知道是否可以更改R中内置函数的默认值？我发现了一些有关在R中为用户设置的函数设置默认值的问题，但对于内置函数却没有设置。

I was wondering if it is possible to change the default value for a built-in function in R? I have found some questions about setting default values for user made functions in R, but not for built-in functions.

为什么要这样做？老实说，这纯粹是为了方便。有时，我会将结果/数据写入.csv文件，以便在Excel中制作一些快速图形。为此，我使用 write.csv 函数。此函数的默认值之一是 row.names = TRUE 。到目前为止，我从来没有想要过Excel文件中的row.name，而且我忘记将 row.names = FALSE 添加到函数数十次了。那么是否可以将此函数的默认值更改为 row.names = FALSE ？

Why do I want this? To be honest, it is purely a matter of convenience. Sometimes I write my results/data to a .csv file to make some quick graphs in Excel. To do this I use the write.csv function. One of the defaults in this function is row.names = TRUE. So far, I have never wanted the row.names in my Excel file and I have forgotten to add row.names = FALSE to the function dozens of times. So is it possible to change the default value in this function to row.names = FALSE?

推荐答案

否。但是，如果您想方便起见，请自己编写包装函数。例如：

No. But if you want convenience, write a wrapper function yourself. For example:

my_write.csv <- function(...) write.csv(..., row.names = FALSE)

然后使用 my_write.csv 。
