Learn R Programming

⚠️There's a newer version (0.9.3) of this package.Take me there.

shinyFiles

This package extends the functionality of shiny by providing an API for client side access to the server file system. As many shiny apps are run locally this is equivalent to accessing the filesystem of the users own computer, without the overhead of copying files to temporary locations that is tied to the use of fileInput().

The package can be installed from CRAN using install.packages('shinyFiles').

Usage

The package is designed to make it extremely easy to implement file system access. An example of implementing a file chooser would be:

In the ui.R file

shinyUI(bootstrapPage(
    shinyFilesButton('files', label='File select', title='Please select a file', multiple=FALSE)
))

In the server.R file

shinyServer(function(input, output) {
    shinyFileChoose(input, 'files', root=c(root='.'), filetypes=c('', 'txt'))
})

It is equally simple to implement directly in your custom html file as it only requires a single <button> element. The equivalent of the above in raw html would be:

<button id="files" type="button" class="shinyFiles btn" data-title="Please select a file" data-selecttype="single">
    File select
</button>

For an overview of all the different modules try the shinyFilesExample() function in the package. It gives an overview of all the necessary code, along with descriptions and working examples.
