Hi Gao,

Thanks for your thorough exploration of gapminder data. In your file, you have clearly showed the whole process starting from loading the library, show the datatype, class, rows, columns, summary, dimension, each property type of invididual variables, histogram. For plot types, you used ggplot with scatter plot, line graph, histogram, which is quite clear and easy to see the result. Furthermore, filter, select, %>% and piping is also well explained, which is nice.

However, you can briefly summarize the property of gapminder$country and table(gapminder$country as it seems that it takes up a lot of space in the page and I cannot clearly seem the data. Perhaps a plot will be a better option to illustrate the data.

Regards Jason

Hello Gao Good exploration on gapminder. You complete all the requirements for the assigenment with different functions and filter, select and piping are well done as well. However, there is a missing readme file in your hw02 folder, and it's better to have a link and description in that readme file. Thanks, Maria
