title: R shiny sliderInput with restricted range
body: <p>In my R shiny sliderInput I want to restrict the range of the input of a given slider with larger maximum value.
  For example assume the input has to be in the interval [1:10]. </p>
  
  <p>Of course I could now define min=1, max= 10 in sliderInput options, but then I will get only a slider with values in this interval.</p>
  
  <p>My goal is to see a slider with values (for example) in [1:50], but the user can move this slider only in the interval [1:10]. This would make my app even better.
  Is this possible?</p>
