trapezoid {RCASPAR} | R Documentation |
A function that calculates the approximate value of the definite integral of a continuous function. In other words, it can help plot the area under the curve of the plotted function between two limits.
trapezoid(x, y)
x |
The values to be used along the x-axis while plotting the curve of the function. The x in f(x)=y |
y |
The values to be used along the y-axis while plotting the curve of the function. The y in the f(x)=y. |
The area under the curve plotted with the x and y values provided as arguments.
Using this method is slightly less accurate than using the simpson integration method
