Dear, I am trying to develop a shiny app of DotPlot for similarity analysis of two sequences using the seqinr library built-in function dotPlot() function. The following is my code
that's okay we all make typos, and it can be really hard to see them sometimes. You provided a good reproducible example so that's great. I don't have the files to input but i've got the app to start up. Some of the fixes
There were a couple of missing parentheses in the ui step.
the fileInput function requires a label argument, this can be NULL - it is a shame that there is no default provided by shiny
in the server function whenever getting values from the app - you need to write input$id_of_input_element
Hope this works for you. I got the app to start up. An error shows up but i assume/hope it will go aways onnce files are selected.
