          Assuming "Obama" is json content structured as the demo example on https://azure.microsoft.com/de-de/services/cognitive-services/emotion/, your could define your output dataframe like this:



          # Define results in data frame
          o <- data.frame(
          value_face_emotion = sapply(
          names(Obama[[1]]$scores)
          ,function(emotion_name) Obama[[1]]$scores[emotion_name][[1]]));
