Ggplot for people who use R is the artist's hands of the genius, the basic use of the method is not mentioned here, you can directly refer to Http://www.r-bloggers.com/search/ggplot
Then sometimes we need to draw a lot of variables, or we need to draw a large number of contrast graphs/tables on a page, so we need to change the width and height of the ggplot, for example
Ggsave (file= "File.tiff", Width=, height=, units= "MM", Limitsize=false)
However, the above statement follows the description of the help file with the wrong page, but running the statement will result in an error because R cannot store such a large TIFF format image, just change the file suffix to. pdf (Note: Limitsize is sure to be set to false).
