x

Correlation data frame or object to be coerced to one via as_cordf.

.predicate

...

Additional arguments to pass to the predicate function if not anonymous.

mirror

Boolean. Whether to mirror the selected columns in the rows or not.

Value

A tibble or, if mirror = TRUE, a correlation data frame.

Examples

# NOT RUN {
library(dplyr)
any_greater_than <- function(x, val) {
  mean(abs(x), na.rm = TRUE) > val
}

x <- correlate(mtcars)

x %>% focus_if(any_greater_than, .6, mirror = TRUE) %>% network_plot()
