How to limit the length of regression line using ggplot2 in R?
To limit the length of regression line using ggplot2 in R, we can follow the below steps −First of all, create a data frame.Then, create the scatterplot using ggplot2 with regression line.After that, create the scatterplot with regression and add xlim function.Create the data frameLet's create a data frame as shown below −x
Read MoreHow to create horizontal lines with two different colors after a threshold in R?
To create two horizontal lines with different color after a threshold in R, we can follow the below steps −First of all, create a plot in base R.Then, add a line to the plot using abline function.After that, use segments function to partially change the color of the line.Create the plotUsing plot function to create a plot in base R −plot(1:5, 1:5, xlim=c(0, 5))OutputAdd a line to the plotUsing abline function to add a line to the plot −plot(1:5, 1:5, xlim=c(0, 5)) abline(h=3)OutputPartially color the lineUsing segments function to color the with yellow color starting from 0 to 3 −plot(1:5, ...
