Put this code below in compile_reports.R, and run it to compile the documents!

library(dplyr)

countries <- c("Austria", "Belgium", "France", "Germany", "Denmark", "Portugal")

for(i in countries){
  rmarkdown::render(input = "example_report.Rmd",
                    output_file = paste0("report_", i, "_", Sys.Date(), ".docx"),
                    rmarkdown::word_document(),
                    params = list(country = i, year = 1990))
}

Your sample was very helpful to me, thank you. I wanted to see how to make the code work with a child template instead of the text option of knit_child which I think is sometimes hard to read. You can get rid of the wrapper function, but have to set the option to ignore chunks with the same name. Also, no indenting in child templates! At least for me it will only produce html and not knitted markdown.
