RDotNet (R.NET) issues in Azure Functions

Question

I have an Azure Function that executes R code by using RDotNet library (R.Net) Everything works fine on my local environment, but when I deploy my code to azure, the process to load specific libraries (zoo, TTR) never ends.

This is my code:

string rHome = @"D:\home\site\wwwroot\R\R-3.4.4";          
string rPath = Path.Combine(rHome, System.Environment.Is64BitProcess ? 
@"bin\x64" : @"bin\i386");                
            REngine.SetEnvironmentVariables(rPath, rHome);  
            if (engine == null)
            {
                engine = REngine.GetInstance();
            }    

            engine.Evaluate(@"library(data.table)");               
            engine.Evaluate(@"library(RODBC)");               
            engine.Evaluate(@"library(nlstools)");                
            engine.Evaluate(@"library(minpack.lm)");              
            engine.Evaluate(@"library(zoo)");
            engine.Evaluate(@"library(TTR)");

The first 4 libraries are loaded without any problem, but when the program tries to load zoo library this process never ends and I cannot continue executing the rest of my code.

No error is displayed so the Azure Function is restarted after some minutes. Same thing happens with library TTR

Any idea on what could be the cause of these symptoms?
