Description Usage Arguments Details Value Author(s) References See Also Examples

Produce a coincidence matrix from a crip set or fuzzy set data.

coincid(x, standardized = FALSE, use = c("complete", "pairwise"))

## S3 method for class 'coincid'
print(x, digits = 3, ...)

overlap(x, y)

`x`	x is a dataframe of crip set or fuzzy set data, which ranges from 0 to 1.
`y`	y is a dataframe of crip set or fuzzy set data, which ranges from 0 to 1.
`standardized`	When TRUE, produce the standardized coincidence scores.
`use`	The method of handling missing data. "complete" means listwise deletion and "pairwise" means pairwise deletion.
`digits`	a non-null value for 'digits' specifies the minimum number of significant digits to be printed in values.
`...`	arguments passed to default method of print.

Coincidence measures the amount of overlap or coincidence between two sets or configurations. The formula is: sum(pmin(x,y))/sum(pmax(x,y)). When standardized is TRUE, the formular is: sum(pmin(x,y))/min(sum(x),sum(y)).

A coincidence matrix.
