Write an object to Google Drive

Saves an R object to a designated location in the project's Google Drive folder. If no custom writing function is provided, the function will infer the appropriate writing method based on the file's extension.

Usage

cloud_drive_write(x, file, fun = NULL, ..., local = FALSE, root = NULL)

Arguments

x

An R object to be written to Google Drive.

file

Path to a file relative to project folder root. Can contain only letters, digits, '-', '_', '.', spaces and '/' symbols.

fun

A custom writing function. If NULL (default), the appropriate writing function will be inferred based on the file's extension.

...

Additional arguments to pass to the writing function fun.

local

Logical, defaulting to FALSE. If TRUE, the function will also create a local copy of the file at the specified path. Note that some writing functions might not overwrite existing files unless explicitly allowed. Typically, such functions have a parameter (often named overwrite) to control this behavior. Check the documentation of the writing function used to determine the exact parameter name and pass it through the ... argument if necessary. Alternatively, you can define an anonymous function for fun that calls a writing function with the overwriting option enabled.

root

Google Drive ID or URL of the project root. This serves as the reference point for all relative paths. When left as NULL, the root is automatically derived from the cloudfs.drive field of the project's DESCRIPTION file.

Value

Invisibly returns a googledrive::dribble object representing the written file on Google Drive.

Default writing functions

Here's how we identify a writing function based on file extension

• .csv: readr::write_csv

• .json: jsonlite::write_json

• .rds: base::saveRDS

• .xls: writexl::write_xlsx

• .xlsx: writexl::write_xlsx

• .sav: haven::write_sav

• .xml: xml2::write_xml

Examples

if (FALSE) { # interactive()
# write mtcars dataframe to mtcars.csv in data folder
cloud_drive_write(mtcars, "data/mtcars.csv")
cloud_drive_write(random_forest, "models/random_forest.rds")

# provide custom writing function with parameters 
cloud_drive_write(c("one", "two"), "text/count.txt", writeLines, sep = "\n\n")
}
