# What is point R?

## What is point R?

points() function in R Language is used to add a group of points of specified shapes, size and color to an existing plot. Syntax: points(x, y, cex, pch, col)

**How do you mark a point on a graph in R?**

To add new points to an existing plot, use the points() function. The points function has many similar arguments to the plot() function, like x (for the x-coordinates), y (for the y-coordinates), and parameters like col (border color), cex (point size), and pch (symbol type).

**What are the different plot types in R?**

Types of R – Charts

- Bar Plot or Bar Chart.
- Pie Diagram or Pie Chart.
- Histogram.
- Scatter Plot.
- Box Plot.

### Are the points a function?

points is a generic function to draw a sequence of points at the specified coordinates. The specified character(s) are plotted, centered at the coordinates.

**Which function is used to draw points markers in a diagram?**

Plot. The plot() function is used to draw points (markers) in a diagram. The function takes parameters for specifying points in the diagram.

**What are the different plot types?**

Five types of plots

- Exposition. Exposition is the beginning of the story and prepares the way for upcoming events to unfold.
- Rising Action. It is that point where the main problem or conflict is revealed.
- Climax.
- Falling Action.
- Resolution.

#### Which of the graphical techniques should be used to plot multiple comparisons in R?

A barplot provides a graphical representation of data in the form of bar charts. The most frequently used plotting functions for two variables in R: plot(x, y): Scatterplot of y against x. plot(factor, y): Box-and-whisker plot of y at each factor level.

**How many PCH are in R?**

The 25 different points symbols are commonly used in R for making beautiful graphs.

**Are points on a graph a function?**

A set of points in the plane is the graph of a function if and only if no vertical line intersects the graph in more than one point.

## What set of points represents a function?

ordered pairs

A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function.

**How do I find a specific data point in R?**

R offers the possibility to do that by conveniently using your mouse. The function “identify()” will allow you to determine which record correspond to a particular data point on the graph, simply by clicking on it.
