Fun Grouped Line Plot Ggplot2
For line graphs the data points must be grouped so that it knows which points to connect.
Grouped line plot ggplot2. Installpackages ggplot2 libraryggplot2 Scatter plot by group ggplotdf aesx x y y color group geom_point. Libraryggplot2 ggplotmtcars aesxwt ympg geom_point ggplotmtcars aesxwt ympg geom_pointsize2 shape23 Note that the size of the points can be controlled by the values of a continuous variable as in the example below. Ggplot2 is a part of the tidyverse an ecosystem of packages designed with common APIs and a shared philosophy.
Add a geom_line layer to the plot. The group aesthetic is by default set to the interaction of all discrete variables in the plot.

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. Line plot with multiple groups. Libraries library ggplot2 library babynames provide the dataset.
Geom_smooth in ggplot2 is a very versatile function that can handle a. This is doable by specifying a different color to each group with the color argument of ggplot2. Create line plots and change line types The argument linetype is used to change the line type.
Plotting separate slopes with geom_smooth The geom_smooth function in ggplot2 can plot fitted lines from models with a simple structure. This R tutorial describes how to create a density plot using R software and ggplot2 package. Change the legend position.
