Remove reliance on plotly htmlwidget

[AliciaSchep]

So as to avoid issues like #6, I think it would be best to remove plotly r package dependence -- iheatmapr creates the list of inputs needed for plotlyjs, could create an iheatmapr htmlwidget instead of using plotly one. Advantages would be:

• more control over what happens when plotly js is updated
• remove crosstalk dependency (not being used with iheatmapr at moment; probably would want a different implementation if it were to be added in future)
• enabling specialized iheamapr shiny event functions (to take into account information stored witihin Iheatmap object)

Dear Alicia,

I recently updated plotly & iheatmapr, so I'll have to adjust my code.

So far I used something like the following my Shiny app:

# ui.R

library(plotly)

fluidPage(
   titlePanel(title = "dummy heatmap app"),
   sidebarLayout(
      sidebarPanel(
          textInput(inputID = "data.rds",
                    label = "Input data",
                    value = "input.data.Rds",
                    placeholder = "Rds file path")
      ),
      mainPanel(
         plotlyOutput(outputID = "heat")
      )
   )
)

# server.R

library(iheatmapr)

function(input, output){
  output$heat <- renderPlotly(as_plotly(main_heatmap(readRDS(input$data.rds))))
}

I guess I know have to change this to

# ui.R

library(iheatmapr)

fluidPage(
   titlePanel(title = "dummy heatmap app"),
   sidebarLayout(
      sidebarPanel(
          textInput(inputID = "data.rds",
                    label = "Input data",
                    value = "input.data.Rds",
                    placeholder = "Rds file path")
      ),
      mainPanel(
         iheatmaprOutput(outputID = "heat")
      )
   )
)

# server.R

library(iheatmapr)

function(input, output){
  output$heat <- renderIheatmap(main_heatmap(readRDS(input$data.rds)))
}

but the vignette still mentions the as_plotly function even after the removal of plotly.R in 3e09ad680d848f380681c63f8d317e0eb4859338.

---

Could you please update the documentation to reflect the changes in the context of shiny?

Best, Marcel

Sorry, there was an error with configuration of website, I had updated the vignette but the website link was pointing to the old version of vignette. Should be fixed now. Vignette includes section on shiny.
