...When trying to run a shiny app I get: Warning: Error in installlibrary: could not find function "installlibrary"

Welcome to the community @pbojczuk! Did you mean to just use library()? If not, can you please share that section of code to help further troubleshoot?

[pbojczuk]

library("tidyverse")
library("WDI")
library("leaflet")
library("sf")
library("rnaturalearthdata")

source("data-processing.R", local = TRUE)

function(input, output, session) {
updateSelectInput(session,
"selected_continent",
choices = unique(countries$continent)
)

observeEvent(input$selected_continent, {
countries_in_continent <- countries %>%
filter(continent == input$selected_continent)

[scottyd22]

I don't see installlibary in this code. Is it possibly in the "data-processing.R" script?

Thank you for getting back! I think this is what you were referring to. Many Thanks UI.r

installlibrary("shinycustomloader")
library("leaflet")

@pbojczuk

installlibrary("shinycustomloader")

This should probably be

library("shinycustomloader")

rather than

installlibrary("shinycustomloader")
