R plot output

[rb643]

Could not find a R specific repo so apologies for posting here.

I'm trying to integrate the dtw twoWay plot into a shiny dashboard but unfortunately keep getting API errors/mismatches when using renderPlot to get the output to a window. I assume this is because the dtw plot output is different from base or ggplot outputs and so I was curious if there is any way around this (rather then me trying to reinvent the plotting function into ggplot somehow..)

It's done in base plot. The source code is in cran. Il lun 19 lug 2021, 13:37 Richard ***@***.***> ha scritto:

Will dig into that, but if its already in base why wouldn't this work:
Running this on the server side

#server.r
output$dtwgen <- reactive({
    fits <- data[,input$select]

    out <- dtw(fits$t1,fits$t2,keep=TRUE)
    return(out)
    
  })
  
  output$dtw_plot <- renderPlot({
    out <- dtwgen()
    dtwPlotTwoWay(out)
  })
  

With this on ui.r side

tabPanel(
          title = "Dynamic Time Warp",
          withSpinner(
            plotOutput("dtw_plot"),
            type = 4,
            color = "#d33724",
            size = 0.7
          )
        )

Generates this...

Graphics API version mismatch seems some technical quibble. In any case, the two-way plot is essentially out$index1 vs out$index2 .

Ah yeah seems to be a linux issue, works fine on the mac..
