check_coordinate_variables: Check coordinate variables

In kueckelj/SPATA: A Toolbox for Spatial Gene Expression Analysis

Check coordinate variables

Description

A member of the lazy-check_*()-family.

Usage

check_coordinate_variables(data, x = "x", y = "y")

Arguments

data	A data.frame containing the variables of interest as well as the variables needed to map onto the x- and y axis of the plot.
x	The name of the numeric variable to be plotted on the x axis.
y	The name of the numeric variable to be plotted on the y axis.

Details

Members of the lazy-check_*()-family take the arguments of their kind - that are used in the function they are called in - and checks whether these arguments input fit the requirements. They stop and return an error immediately once they stumble upon something invalid. They do not alter or adjust input and return TRUE if the whole function has been executed without anything invalid being found.

Value

A logical value TRUE if nothing invalid has been detected or an informative error message.
