Can anyone help me revise my code so that I can achieve the following goals.
1.How to make the table to be on the top of the first page? Now it skips the first page and jumps to the middle of the 2nd page.
2.The plots don't look good. Is there a way to make them 2x2 right on the top of the 2nd page. Like the image I attach(which is 1x3, but I want 3x2, not sure if 2x3 look nicer).
3.Any other revision is extermely welcome!
