| library(rstanarm) | |
| library(prophet) | |
| library(CausalImpact) | |
| # This will test that rstanarm works | |
| # Don't be alarmed if you get a warning about "divergent transitions " | |

It seems like it's not rstanarmthat is the problem, but the openssl dependency.
Does install.packages("openssl") work?
If not, that's where you would have to start digging... Sorry for not being more specific! :)

@rasmusab Thanks for your comments!
I finally got rstanarm to work by before installing it running sudo apt install libssl-dev (see the comment related to Ubuntu here https://github.com/rocker-org/rocker/issues/124).
@rasmusab Is this the expected output? There is some output regarding "Disabling yearly seasonality." and warnings regarding "Removed 52 rows containing missing values (geom_path)."

Thank you Rasmus, my script is working with graphs plotting fine but i understand what am running can you please explain what we are trying to achieve even if there is a document to study.
@serifatf The only purpose of this script is to see if you have correctly installed the three packages, nothing else :)

Hi all,
I have some problems installing
rstanarm.When I run
install.packages("rstanarm")I get following errors:I have tried running
sudo apt-get install libcurl4-openssl-dev(suggested here https://discourse.mc-stan.org/t/install-issues-with-shinystan-with-r/1506 andsudo apt update && apt install libssl-dev(suggested here https://github.com/rocker-org/rocker/issues/124. I have also tried runninginstall.packages(c("Rcpp", "RcppEigen", "rstan", "rstanarm")), accoring to the suggestions from https://github.com/stan-dev/rstanarm/issues/90. However, I still cant installrstanarm.I am running R from RStudio, and I have the following system:
Any ideas on what the problem can be?
(Installing the other packages worked fine for me).
Best,
Samuel
