My situation is the following:
I made a package (named MyCDM) with several functions that I constantly use in my applications. When I running the scripts in my PC (I use Rstudio), I include the command library(MyCDM) and all works fine.
The problem is that I wanted to migrate the execution of my script to a cloud service of my University, where I don't have the privilege of include new packages.
I want to export all functions of MyCDM package into a single R file, in a way that I can copy this file into the University server and source it in my script.
I know that I could copy the "R" folder of my package and paste it on the destination folder. But the University site guides us to avoid to copy/read/write operations with a large number of small files due to the impact the server's performance.
I was able to import all functions to my global environment, but I don't know how to write the function body's into a file.
There is a way to do it in a simple manner?
(ps.: English is not my first language. Sorry for any language mistake. If I not made myself clear, please ask for clarification in the comments)
One solution is to just use R to copy and paste the contents of each file in the R directory into a new file:
purrr::walk(
.x = list.files(path = "R/"),
.f = ~write(
readLines(file.path("R", .x)),
file = "functions_script.R",
append = TRUE)
)
This gets a list of all files in the R directory (assuming your working directory is currently the root of the package, although you could easily change this) using list.files. Then copies and writes the contents of each file to a new file functions_script.R, (and appends each additional file).
