Warning: Error in dashboardPage: could not find function "dashboardPage"

[yusuzech]

I need to manually load library shinydashboard first to launch MLstudio, otherwise it returns \:

> MLstudio::runML()
Warning in data(package = packages.list$Package) :
  datasets have been moved from package 'base' to package 'datasets'
Warning in data(package = packages.list$Package) :
  datasets have been moved from package 'stats' to package 'datasets'

It could be that there is another package that masked or blocked shinydashboard from running. Could you please send me the output of the search() functions?

Search returns:

Thanks, are you loading the MLstudio package or call the function with MLstudio::runML? The MLstudio has two dependencies packages - shiny and shinydashboard, if using the last option to open the app then you will have to load the dependencies manually.

I was using the last option. Thank you!
