variable is set to a dataframe. This dataframe contains
|
|
one row for each selected file, and the following
|
|
columns: \describe{ \item{\code{name}}{The filename
|
|
provided by the web browser. This is \strong{not} the
|
|
path to read to get at the actual data that was uploaded
|
|
(see \code{datapath} column).} \item{\code{size}}{The
|
|
size of the uploaded data, in bytes.}
|
|
\item{\code{type}}{The MIME type reported by the browser
|
|
(for example, \code{text/plain}), or empty string if the
|
|
browser didn't know.} \item{\code{datapath}}{The path to
|
|
a temp file that contains the data that was uploaded.
|
|
This file may be deleted if the user performs another
