Installation Issues rstan and rstanarm

Hi everyone,

I am a student/ newbie to rstan and rstanarm to do my stats homework. I have been trying to download both, but I keep running into the same issue with rcppParallel. I was wondering if anyone can guide me in the right direction in fixing this problem. I am not a programmer and would really appreciate some guidance. Thank you for your time.

install.packages("rstan", repos = "https://cloud.r-project.org/", dependencies = TRUE) 


There are binary versions available but the
  source versions are later:
             binary source needs_compilation
RcppParallel  5.0.2  5.0.3              TRUE
rmarkdown       2.6    2.7             FALSE

Thank you again for your time.

Respond ‘No’ when it asks if you’d like to install the package from source that needs compilation

Thank you so much! I’ll try that now.
