get_mean_median: Extract mean and median correlation coefficient values

Description Usage Arguments Value Examples

View source: R/get_mean_median.R

Description

Takes the output of correlate_windows and extract the mean and the median correlation value for each window comparison.

Usage

1
get_mean_median(df, absolute_cc = TRUE)

Arguments

df

A data frame, usually the output of correlate_windows.

absolute_cc

Should the function work of absolute value of correlation coefficients? Default to TRUE to simplify plots and avoid annoying, non-symmetrical, near 0, shifts of distributions.

Value

A data_frame with columns bin, window, mean and median.
