Create a graphic with fitted line based on numerical variables.
plot_lines( .data, x, y, fit, level = 0.95, xlab = NULL, ylab = NULL, col = "red", alpha = 0.2, size.shape = 1.5, size.line = 1, size.text = 12, fontfam = "sans" )
.data | The data set |
---|---|
x | The variable in data to be shown in the x axis |
y | The variable in data to be shown in the y axis |
fit | The polynomial degree to use. It must be between 1 (linear fit) to 4 (fourth-order polynomial regression.) |
level | The fonfidence level |
xlab | The x lab |
ylab | The y lab |
col | The colour to be used in the line plot and points |
alpha | The alpha for the color in confidence band |
size.shape | The size for the shape in plot |
size.line | The size for the line in the plot |
size.text | The size of the text |
fontfam | The family of the font text |
