save location does not pops up; directly launches the file

[shantanubafna]

output$saveMetaData <- downloadHandler(
    filename = function(){
      paste("meta",".txt")
    },
    content = function(file2){
      write.table(v$scData@meta.data, file2, quote = F, row.names = T, col.names = T, sep = "\t")
    }
  )

Hi @shantanubafna, please try to include more information next time

I believe you're referring to the fact that if you click on a download button, the file gets downloaded without prompting you for a location to save. If you want to decide where to save it, try right clicking on the button and choosing "Save link as..." (or the equivalent in your browser).

Sorry. I'll keep that in mind. Thanks! that works

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

SOLUTION

Data <- downloadHandler(
    filename = function(){
      paste("normalized",".txt")
    },
    content = function(file1){
      #reading it as matrix as normalized data is sparse matrix
      write.table(data.frame(**as.matrix(v$scData@data)**), file1, quote = F, row.names = T, col.names = T, sep = "\t")
    }
  )
