cor_wo_shared_zero: Correlation without shared zeros

In abichat/correlationtree: Functions about correlation tree

Description

Remove positions where x=y=0 and then compute correlation.

Usage

cor_wo_shared_zero(x, y, ...)

Arguments

x	a numeric vector with positive or null entries.
y	a numeric vector with positive or null entries.
...	arguments to be passed to cor such as method (see details).

Details

For method: one of "pearson" (default), "kendall", or "spearman".

Value

The estimated correlation coefficient between x and y after removing shared zeros.

Examples

x <- c(0, 7, 5, 0, 2)
y <- c(8, 0, 0, 0, 2)
cor_wo_shared_zero(x, y, method = "spearman")
cor(x[-4], y[-4], method = "spearman")
