일리노이대학교 어버너-섐페인캠퍼스의 Analyze City Data Using R and Tableau 학습자 리뷰 및 피드백

Cloud desktop is very laggy even writing something is not responsive. I can't download any course material (I dont know why, but the downloading process is never end). Despite that, I like the topic. For first time, I know R languange+OSM+Tableau which usefull to analyze city data

The response time of the Rhythm platform is too slow. I feel lagging for every single character I type. very annoying. The teaching method is not efficient.

Excellent course, I really got a lot out of it. Recommended.

Overall, this course provides a good overview of the power and possibilities of R and Tableau. If you are not currently comfortable working with R, I wouldn't recommend this class. I wish the class had a specific research question -- a lot of the cleaning in R felt arbitrary without know what our end goal was. Note that you'll need to sign up for a free trial of Tableau -- that wasn't clear at the beginning of the course.

Thank you Jose Luis Rodriguez

Poor R code, throws up errors often
