cloud_drive_upload: Upload a local file to Google Drive

Description

Uploads a local file from the project's directory to its corresponding location within the project's Google Drive root folder.

Usage

cloud_drive_upload(file, root = NULL)

Value

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

Arguments

file

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

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.

Details

Google Drive file structure is different from the usual file structure like e.g. on Linux or Windows. A folder on Google Drive can have two or more child folders with the same name. Google Drive marks files and folders with so-called id values to distinguish between them. These values are always unique. You can see them in browser URL for example. The concept of "name" is in the first place for convenience of the end user.

In such a setup a relative file path may correspond to multiple files or folders. This function however works under assumption that the relative path you pass to it defines strictly one object. If there's any ambiguity it throws an error.

Examples

if (FALSE) { # interactive()
# create a toy csv file
dir.create("toy_data")
write.csv(mtcars, "toy_data/mtcars.csv")

# uploads toy_data/mtcars.csv to 'data' subfolder of project's 
# Google Drive folder
cloud_drive_upload("toy_data/mtcars.csv")

# clean up
unlink("toy_data", recursive = TRUE)
