TA comments

[Rashedul]

• Your readme file had a good description of your directory and you linked the files which was great.

• You can add chunk names here: https://github.com/STAT545-UBC-students/hw02-liming17/tree/master/hw02_files/figure-gfm

• To attach packages you can use suppressPackageStartupMessages() function to suppress messages.

• Use proper indentation for readability. For example,

#bad
ggplot(gapminder, aes(year, pop)) + scale_y_log10() + geom_point(alpha=0.1)

#good
ggplot(gapminder, aes(year, pop)) + 
    scale_y_log10() + 
    geom_point(alpha=0.1)

• Use proper spacing e.g., alpha = 0.1 instead of alpha=0.1.

• In chuck/Inline comments people generally avoid to explain "what" the code does because . Instead they use "why" comments. Some of your comments explained what the code does, which is information that the code already contains.

• Overall you have done a great job!
