Using an .Rds file in power BI

Dear community,

I am creating a map in my Power Bi report using R visuals. The library(sp) to be precise.

To create the map I am interested in, I need a SpatialPolygonsDataFrame that I can easily find online as an .rds file.

When creating the R visual, I need to have this data frame ready for usage. However, in the query process, it is not possible for me to extract something like an .rds file. 

For this reason, I extract the .rds file directly from R visual script editor, using something along the lines of

# get spatial data for country
con <- url("https:/.../countrySpatialData.rds")

spatialDataFrame <- readRDS(con)

It works like a charm! But at the time of seeing the report already published, I encounter the following error:

Script Runtime Error
Error in readRDS(con) : cannot open the connection In addition: Warning message: In readRDS(con) : InternetOpenUrl failed: 'The server name or address could not be resolved'

My assumption is that PowerBI app does not allow me to stablish a connection using the R visual script runner.

Does anyone have an idea as to how to access .rds files using the R visual script runner?

Thank you in advance

Paulo

p.s. I have come across this post already https://community.powerbi.com/t5/Desktop/load-R-rds-file-within-R-visual-in-PBI-service/m-p/506305#M236419 , but it unfortunately does not solve the problem.
