A few months ago, I built a shiny app, with a plotly graph as my main output. My data is from an excel sheet, and I have used the readxl
package to pull the data into R.
I recently updated the excel data, and now plotly will no longer graph the data.
From the shinyapp:
ratings <- read_excel("data/excel.xlsx", sheet = "Ratings")
p <- plot_ly(ratings, x = ratings[,1],
y = ratings[,input$select[1]],
name = input$select[1])
is the beginning building block for the output. When I launch the app, I see an error message
Error: Unsupported index type: NULL
where the plot used to be. I have tried to build the plot step-by-step in RStudio, but my output is a blank x,y graph without any data points. If I manually build vectors:
xVector <- c(1:5)
yVector <- c(1:5)
plot_ly(x = xVector, y = yVector)
I get a fully-functioning plotly
graph.
