WhereXY: Count points in a scatter plot

Description

count the number of points that fall into various sized subparts of a scatter plot. The graphing region can be split into cells based on a uniform or normal marginal distribution for both x and y variables.

Usage

WhereXY(x, y, grid = c(3, 3), Dist = "uniform")

Arguments

x

vector of x coordinates.

y

vector of y coordinates

grid

pair of values to split the graph into how many parts.

Dist

the distribution the variables might be expected to follow

Value

• A text descriptionof the number of points in each subregion of the scatter plot. The table of counts should be compared to the expected number of points in each subregion.

Examples

x=rnorm(50)
y=rnorm(50)
WhereXY(x,y)
