Wonderful Ggplot Geom_line Group
A categorical variable that specify the group of the observation The idea is to draw one line per group.
Ggplot geom_line group.

Within geom_line that means mapping a variable to different lines.

The major difference in these first two lines is that we modified the color and the size of the line inside of geom_line.
Geom_line connects them in order of the variable on the x axis. The group mapping allows us to map a variable to different groups. By default ggplot2 uses the combination of all categorical variables in the plot to group geoms - that doesnt work for this plot because you get an individual line for each point.
The rule is simple. In addition to those there are 3 other main aesthetic mappings often used with geom_line. The group aesthetic is by default set to the interaction of all discrete variables in the plot.
By default the line geom inherits the color argument from the call to ggplot. The group argument tells ggplot which observations belong together and should be connected through lines. Fitted lines can vary by groups if a factor variable is mapped to an aesthetic like color or groupIm going to plot fitted regression lines of resp vs x1 for each grp.
Geom_path connects the observations in the order in which they appear in the data. Plotting separate slopes with geom_smooth The geom_smooth function in ggplot2 can plot fitted lines from models with a simple structure. Library plotly datn.
