Hi Shuqi,
Below are some notes I took as I read. I think this is a nice start, but there's plenty to clean up still. For example, I'm really not sure you need to plot the value on the y axis as text so often. If you do, I would clean it up (e.g., round it, format it more cleanly, etc). I also think you can take more time to explain each plot.

With that said, nice job on this. Please let me know if you have any questions.

• Nice dataset. I would describe it a little bit more, in terms of where you got it from.
• Describe to the reader the difference between conventional and organic
• Trend of average price per year in whole country
  • If you wish to plot the average values as text (which you definitely don’t need to), I would be sure to round them to two decimal places
  • Also use scale_y_continuous() to set minimum and maximum points on the scale. Probably 1 as a minimum and 2 as a maximum
• Trend of average price from June to march per year in whole country
  • Could you clarify what you are plotting? Is it the difference between June and March?
  • It looks like you are graphing the average price across jan, feb, and march for each year…I’m not sure that’s the best way to answer this question. Could you try just plotting jan 2015, feb 2015, mar 2015, jan 2016, feb 2016 etc?
  • Also fix title to say January and not June
  • Unclear why you repeated this plot
• Total volume plot
  • See above comment.
  • If you include this plot, I would clean it up bit.
• Could you clarify what this line is doing?
  • mutate(Total_volume = replace(Total_volume, Total_volume%/%1 == 1334206069, 5053904733), Total_volume = replace(Total_volume, Total_volume%/%1 ==48532271, 208486943))
• Annual trend of total valoume….
  • Fix title
  • Fix geom_text() labels
  • I would probably not use a regression method to extrapolate for the rest of the year in 2018…this is generally not best practice when using such a model, and when the reader can’t see the results of the regression it is extremely difficult to interpret.
• Annual trend of total bag valoume
  • Fix title
  • Fix legend labels
  • Fix geom_point() labels
• The annual trend of total valoume in whole country
  • What is the difference between this and bag volume?
  • Fix title
  • Something strange is going on with the geom_line() function here. It seems to loop around itself in 2015. Please check that out.
• Make sure to clarify the difference between bag size and avocado size.
