[英]How to load all my functions in my project automatically in R
I am writing more than 6 functions and save them in my R.project. 我编写了6个以上的函数,并将它们保存在我的R.project中。 Every time, to start working using my project, I need to run each function manually one by one.
每次开始使用我的项目时,我都需要手动逐个运行每个功能。 Is there a way that I can load all these functions automatically?
有没有一种方法可以自动加载所有这些功能?
You have two options: 您有两种选择:
Create your own package and load it on the start-up, you will have all the function available. 创建您自己的程序包并在启动时加载它,您将拥有所有可用的功能。 A tutorial

Customize R start-up loading automatically your R files containing your functions. 自定义R启动,自动加载包含功能的R文件。 A tutorial and an example

If you don't wish to take the package approach (which I agree is the best approach), you could stack all your functions on top of one another in an R script and source it on startup. 如果您不希望采用包方法(我同意这是最好的方法),则可以将所有函数彼此堆叠在R脚本中,并在启动时将其作为源。 One step instead of 6. End up with all the functions in your .GlobalEnv
一步代替6。最后完成.GlobalEnv中的所有功能
Put this in an R script: 将其放在R脚本中:
###Put in a script
eeee <- function(){
cat("yay I'm a function")
}
ffff <- function(){
cat("Aaaaaah a talking function")
}
If you use RStudio, the code would be as below. 如果使用RStudio,代码将如下所示。 Otherwise change the source location.
否则,请更改源位置。 Do this in console (or in a script):
在控制台(或脚本)中执行以下操作:
###Do this
source('~/.active-rstudio-document')
Then you can do: 然后,您可以执行以下操作:
eeee()
yay I'm a function
ffff()
Aaaaaah a talking function
You can run the below script before starting your work: 您可以在开始工作之前运行以下脚本:
source_code_dir <- "./R/" #The directory where all source code files are saved.
file_path_vec <- list.files(source_code_dir, full.names = T)
for(f_path in file_path_vec){source(f_path)}
