How to tell CRAN to install package dependencies automatically

Question

I develop a package in R and when I check and build it in my local computer it works properly  But when I tried it in CRAN  I get a package dependencies error  My package depends on two functions of other packages     If I list the other packages under the description using Depends or imports  will it be automatically installed with the new package  Or do I need to explicitly invoke the function install packages  packagename   under the function that I ve used the other packages  if this all is wrong  what is the best way to solve package dependencies in R inorder to pass the R CMD check and build test and submit to CRAN   Thank you

Another possibility is to select the Install Dependencies checkbox  In the R package installer  on the bottom right

On your own system  try   install packages  foo   dependencies        with the dependencies  argument is documented as  dependencies  logical indicating to also install uninstalled packages       which these packages depend on link to import suggest  and so       on recursively    Not used if    repos   NULL      Can also be a       character vector  a subset of    c  Depends    Imports          LinkingTo    Suggests    Enhances              Only supported if    lib    is of length one  or missing   so it       is unambiguous where to install the dependent packages   If       this is not the case it is ignored  with a warning         The default     NA     means    c  Depends    Imports          LinkingTo                 TRUE    means  as from R 2 15 0  to use    c  Depends          Imports    LinkingTo    Suggests      for    pkgs    and          c  Depends    Imports    LinkingTo      for added       dependencies  this installs all the packages needed to run          pkgs     their examples  tests and vignettes  if the package       author specified them correctly     so you probably want a value TRUE   In your package  list what is needed in Depends   see the  Writing R Extensions manual which is pretty clear on this
