Hello , using flexdashboard i can upload and visualize csv file but when i upload text file or any other file it is showing csv output and when i select radio button as text or tab file is not showing in output can anyone help how to see any format file using flexdashboard.

Below is my code :

*Data - Upload*

```{r}
fileInput('file1', 'Choose CSV File',
                accept=c('text/csv', 
                         'text/comma-separated-values,text/plain', 
                         '.csv','.tsv'))
checkboxInput('header', 'Header', TRUE)  
radioButtons('sep', 'Separator',
                   c(Comma=',',
                     Semicolon=';',
                     Tab='\t', Text=".txt", Excel=".xls")
              )
radioButtons('quote', 'Quote',
                   c(None='',
                     'Double Quote'='"',
                     'Single Quote'="'"),
                   '"')

data read

```{r} data <- reactive({ req(input$file1) ## ?req # require that the input is available

inFile <- input$file1 

# tested with a following dataset: write.csv(mtcars, "mtcars.csv")
# and                              write.csv(iris, "iris.csv")
df <- read.csv(inFile$datapath, header = input$header, sep = input$sep, quote = input$quote)
return(df)

}) ```

{r} renderTable({ data = data() data })

output i am getting as:
