Dear Rajendran Arun,
Here is my peer review process:
I did not understand that the x axis (index) represents in this plot function (plot(type='p',gapminder$gdpPercap) # scatter plot), so if you have enough time, don't hesitate to let me know what I missed (but if not, that's totally fine too)
Optional - Section: But I want to do more!
Thank you so much for teaching me the following items:
Again, excellent job !!

Created a Homework 02 Folder. Files are well organized in this folder. So it was easy for me to navigate. The Readme file for Homework is quite helpful. I appreciate particularly the section on the resources that helped the student. Now I am inspired to use them as well. Links to the R markdown document and Rendered Markdown File were a nice touch.
The exploration of the data and the demonstration of functions are quite comprehensive. Dividing the work flow into clear sections and subsections would have made reviewing the R markdown document easier. The reflection of the process needs to be elaborated as well. For instance, why did the student install kableExtra? What does it do? The purpose might be quite evident for him, but not for the beginners of R such as myself.
All in all, a very solid effort.
Hello @abishekarun ,
Smell test the data You answered all the questions and got the number of variables and observations in more than one way. You explained how these functions are different in application contexts specifically.
Explore individual variables You explored two categorical variables and two quantitative variable and visualized them using tables and different kinds of plots.
Explore various plot types You performed a deep and comprehensive exploration on various kinds of plots such as scatter plot, histogram, density plot, box plot and pie chart.
Use filter()
, select()
and %>%
Yes. You used all of these.
Bonus
You explained how the code should be changed to get the correct result.
You used knitr::kable()
to present tables in many places.
You also used other dplyr functions including mutate()
, group_by()
, summarize()
, etc.
You did a very good job. Your repository is well organized. The markdown file is easy to find. You demonstrated deep understanding in using different kinds of plots to visualize the data.
