shiny - Error in RShiny ui.r argument missing -


trying create ui.r file plotting logistic regression following features:

selecting inputs (y-variable: breakdown, x-variables: temperature, humidity, hours) , variable range slider.

i got following error: error in tag("div", list(...)) : argument missing, no default

require(shiny)  shinyui(pagewithsidebar(   headerpanel("home automation data model - tv"),   sidebarpanel(       wellpanel(          selectinput(inputid = "x_var",                      label = "x variable",                      choices = c("temperature (celcius)" = "temp", "humidity (percentage)" = "hum", "hours" = "hrs"),                      selected = "temperature"                      ),           uioutput("x_range_slider")      ),        wellpanel(          selectinput(inputid = "y_var",                      label = "y variable",                      choices = c("breakdowns (yes/no)" = "y"),                      ),           uioutput("y_range_slider")      ),        wellpanel(          p(strong("model predictions")),          checkboxinput(inputid = "mod_logistic",    label = "logistic (dot-dash)"),          conditionalpanel(              condition = "input.mod_loess == true",              sliderinput(inputid = "mod_loess_span", label = "smoothing (alpha)",                  min = 0.15, max = 1, step = 0.05, value = 0.75)          )      )  ),   mainpanel(      plotoutput(outputid = "main_plot"),       conditionalpanel("input.mod_logistic == true",          p(strong("logit model")),          verbatimtextoutput(outputid = "mod_logistic_text")      ),  )

))

error in tag("div", list(...)) : argument missing, no default

delete last comma in ui.r file. it's expecting argument after comma.
