Error in force(ui) : could not find function "fluidPage"

[Mohan Radhakrishnan]

Hi,

       I thought after installing 'shiny' I can use functions like fluidPage. Isn't that so ?

Thanks,

Mohan

Hi,

did you load the package?

library(shiny)

best H

Ofcourse.
               Other examples are working.

Thanks

[Herman Sontrop]

well it's a good step ;-) I agree that after loading the fluidPage function should be there... can you provide a minimal example?

This is ui.R

Other examples that are working don't use this function. I tried without the 'theme' also.

library(shiny)

shinyUI(fluidPage(theme = "bootstrap.css",

  titlePanel("Legerdemain"),

  navlistPanel(

    "Garbage Collection",

    tabPanel("Generations",

      h3("Heap")

    ),

    tabPanel("Threads",

      h3("Threads and Locks")

    ),

    "-----",

    tabPanel("JIT",

      h3("Methods")

    )

  )

))

Thanks,

Mohan

You are likely to be using an outdated version of shiny. Please
provide library(shiny);sessionInfo(), or run update.packages(ask =
FALSE).

I updated.  

Should I use a newer version of R or shiny again ?

Ok. I am using a newer version of the pre-built binaries of R for OSX and shiny 0.9. Now it is working.

Thanks,

Mohan

R 2.15.1 and shiny 0.5 are way too old. Whenever you have got trouble,
check if there are new versions of packages (either R or R packages),
and test them if there are.
