I am using plotly r to plot a chart in a R shiny app. The following is the error :
No applicable method for 'ggplotly' applied to an object of class "NULL
The same thing works fine when I do plot it in R but not when in shiny. Below is the data which is being plotted and the code used in R shiny.
Month_considered pct.x pct.y pct
