What does the error message "cannot coerce type 'closure' to vector of type 'any'" mean?

[vac...@kenyon.edu]

Hi everyone, 

I am relatively new to Shiny, but I'm working under a tight deadline and I'm very stuck. I am getting the error message "cannot coerce type 'closure' to vector of type 'any'." Can anyone give me insight into what this means? For more background, I am running a SIR epidemic model, which requires the desolve package. This seems to be the section of code that's giving me trouble (in my server component). I am not sure exactly where the problem is, but any help would be greatly appreciated. 

times <- seq(0, 150, by = 1)

  out <-reactive({

    out<-renderDataTable(ode(y= init, times = times, func = sirvac, parms = parameters))

  })

output$curves<- renderPlot({

  matplot(times, out(), type = "l", xlab = "Time", ylab = "Susceptibles and Recovereds", main = "SIR Model", lwd = 1, lty = 1, bty = "l", col = 2:4)

  legend(40, 0.7, c("Susceptibles", "Infecteds", "Recovereds"), pch = 1, col = 2:4)

  })

Thank you!!

Your `out` reactive is wrong--renderDataTable should never be used for anything other than being assigned to output$something. I don't know what "ode" is, but I assume it should be like this?

out <- reactive({

  ode(y= init, times = times, func = sirvac, parms = parameters)

})

but are there supposed to be any reactive inputs or whatever referred to in there?
