renderLeaflet(expr, env = parent.frame(), quoted = FALSE)

Arguments

outputId	output variable to read from
width, height	the width and height of the map (see shinyWidgetOutput)
expr	An expression that generates an HTML widget (or a promise of an HTML widget).
env	The environment in which to evaluate expr.
quoted	Is expr a quoted expression (with quote())? This is useful if you want to save an expression in a variable.

  server = function(input, output) {
    map = leaflet() %>% addTiles() %>% setView(-93.65, 42.0285, zoom = 17)
