shinyFilesDropBox-parsers: Convert the output of a selection to platform specific...
In armelmoth/shinyFilesDropBox: What the package does (short line)

Description Usage Arguments Details Value See Also Examples

This function takes the value of a shinyFiles button input variable and converts it to be easier to work with on the server side. In the case of file selections and saving the input variable is converted to a data frame (using parseDropFilePaths() or parseDropSavePath() respectively) of the same format as that provided by fileInput. The only caveat here is that the MIME type cannot be inferred in file selections so this will always be an empty string and new files doesn't have a size so this is left out with file saving. In the case of folder selection the input variable is converted to a string (using parseDropDirPath()) giving the absolute path to the selected folder.

parseDropFilePaths(selection, roots = c(Home = ""))

parseDropDirPath(selection, roots = c(Home = ""))

parseDropSavePath(selection, roots = c(Home = ""))

`selection`	The corresponding input variable to be parsed
`roots`	The path to the root as specified in the `shinyDropFileChoose()` call in `shinyServer()`

The use of parseDropFilePaths makes it easy to substitute fileInput and shinyFiles in your code as code that relies on the values of a file selection doesn't have to change.

A data frame mathcing the format of fileInput
