R scatterplot with line. You can plot the fitted value of a linear regression. Basic R also allows to build connected scatterplot thanks to the line function. On the other hand if youve got a line which is wobbly and you dont know why its wobbly then a good starting point would probably be locally weighted regression or loess in R.

Enhanced Scatterplot of MPG vs. If we plot unemployment without any lines or anything fancy it looks like this. We can add any arbitrary lines using this function.

Ggplot iris aes xPetalLength yPetalWidth geom_point stat_smooth methodlm By default stat_smooth adds a 95 confidence region for the regression fit. Now it will be visible. Thus you just have to add a geom_point on top of the geom_line to build it.

Suppose this is your data. Here we can make a scatterplot of the variables write with read. Weight by Number of Car Cylinders.

Each of these features is optional. Reg1. With ggplot2 we can add regression line using geom_smooth function as another layer to scatter plot.

Plot yx abline lm yx colred mainCheck the axis labels Flip the variables in the plot command. The first part is just the first plot we already did but I add in a vertical line at the average weight and add in text. You just need to use the b option of the type argument.
