## ----comparison---------------------------------------------------------------
#  # Compare translations across services
#  text <- "The weather is beautiful today"
#  
#  # Apertium translation
#  apertium_result <- apertium_translate(text, "es", "en")
#  
#  # MyMemory translation (also free, but different approach)

#  data.frame(
#    Service = c("Apertium", "MyMemory"),
#    Translation = c(apertium_result, mymemory_result),
