How to insert a function from another package in the server.R - Shiny?

Question

I'm trying to insert a table on Shiny that is gonna be generated from a rLiDAR function. However, I'm having trouble to figure out how to insert this function in server.R. Here's what I was trying to do:

output$summary <- renderTable({    
  table <- summary(Arv.List)    
  Arv.List<-FindTreesCHM(chm, sws, hmin)    
})

The function is FindTreesCHM(chm, sws, hmin)

Does anyone have a clue of how to make it works?

Answer 1

Try

output$summary <- renderTable({    
  Arv.List <- FindTreesCHM(chm, sws, hmin)    
  summary(Arv.List)    
})
