Select Input in ggplot Shiny dashboard - Error: object not found

Question

I am trying to create ggplot output using R Markdown Shiny Document. I need it to plot data based on the selection in a dropdown menu. My code:

df<- data.frame(df,out)
renderRpivotTable({
rpivotTable(data = df, rows = c("organisationunitname","X2"), cols = "X1", vals = "value",
            aggregatorName = "List Unique Values",inclusions = list(organisationunitname=list("All OUs")),
            rendererName = "Lab Table", width = "100%", height = "500px")  })

orgunit <- c("Cy3L", "Yieu", "j9ao", "H3LY", "U3nd", 
"qU1l", "jXVh", "dXHb", "tCq8", "Blee", "5jra", "qO2V", "Qa9J", 
"2XIy", "MJpY", "tNKa", "UorU", "7pZt", "Mxsz", "WCkd", "BiDp", 
"Zw8w", "0J7c", "9YtI", "TAkB", "py3Q", "RdQt", "Yhv1", "PB0X", 
"H3L4", "INY7", "DpTW", "3zXP", "OqpO", "tiZU", "5wnz")

inputPanel(selectInput("OU", label = "Select OU:", choices = orgunit, selected = "All OUs"))


renderPlot({
  df1=reactive({return(df[organisationunitname %in% as.character(input$OU)])})
  ggplot(data = df1(),aes(x=X1,y=value))+geom_bar(stat = "identity")+facet_grid(X2~.)
})

It gives me this error: object 'organisationunitname' not found Error Message

My data:

I am not sure why it's not reading the "organisationunitname" column. Please help.

Answer 1

I think your error is this line:

 df1=reactive({return(df[organisationunitname %in% as.character(input$OU)])})

Change it to:

df1=df[df$organisationunitname %in% as.character(input$OU),])

You also have the incorrect number of dimensions and reactive is not required here because the expression is already in a reactive function: renderPlot.
