You can take the file extension and use the appropriate file reader according to this extension.

In ui :

fileInput("file", "Upload a file")

In server :

dataset <- eventReactive(input$file, {
  extension <- tools::file_ext(input$file$name)
  filepath <- input$file$datapath
  switch(extension,
    csv = read.csv(filepath),
    xls = readxl::read_xls(filepath),
    xlsx = readxl::read_xlsx(filepath)
  )
})
