Graph regression in r
WebApr 29, 2016 · I have a data frame of mammal genera. Each row of the column is a different genus. There are three columns: a column of each genus's geographic range size (a continuous variable), a column stating whether or not a genus is found inside or outside of river basins (a binary variable), and a column stating whether the genus is found in the … Web1 day ago · and the graph looks like below. Now in location C, it does not show the linearity. So I want to not show the regression line (or provide different color or dotted line, etc.,) in only location C. Could you let me know how to change regression line type per group? Always many thanks!!

WebApr 14, 2024 · When we draw regression lines for a group, they are usually of the same type, such as simple linear regression. Here is an example using yield data for different nitrogen rates per genotype. Then, the regression graph for each group would be shown below. I think it would be better to show the quadratic regression line for genotype A. In …
