HW02_Bei Wang resubmission #44
Conversation
…ushing these files in github, I only pushed .Rmd but not other. I realize Rmd cannot be rendered in github.

I used
iris$Species <- factor(iris$Species, levels = c("versicolor","setosa","virginica"))
for changing the order
This might still be complicated if there's lots of species

This seems like a simpler way of changing the order for this specific set!

I think you can set a value to x/xmin/xmax. I tried it and found that 1 is the center of the first item, 2 is the second, 1.5 is the boundary of the first and the second, etc.

Nice way of highlighting your answers and comments! I will try using it in my code.

I didn't add height = 0 and I got randomly arranged dots instead of aligned ones. Thanks because now I know how to fix it, but I am still confused about what did setting height to 0 actually change...?

the position_jitter (height=) sets the resolution of the jitters on the y axis; the default is set to 0.4. Here it is actually x-axis because I flipped the coordinate. Since the x axis (Car class) is a categorical variable that composed integers. So in order to have the jitter only be set to integers, height should be set to 0. I didn't find much about this function, so this is just what I think it might be:)

For the dots you got by not setting height=0, I'm guessing its arranged by every 0.4?
This is a resubmission, I previously didnt push all files but only two .Rmd, which can't be rendered on github (can't be viewed). Turned out that I should've pushed all of them.
