Print a Correlation Matrix with Special Formatting
Description
Display a correlation matrix in readable, compact form.
Usage
corPrint(R, min_value=0)
Arguments
R |
Square, input correlation matrix. |
min_value |
The minimal value in magnitude of the displayed correlations. |
Details
Drop the 0. characters of each displayed correlation coefficient. For example, display 0.42 as 42. Have an option to only display correlations larger in magnitude than a minimum threshold, so that all correlations between -min_value and +min_value display as blank spaces.
Value
The output correlation matrix.

colnames(mycor) <- c("X1", "X2", "X3", "X4", "X5", "X6")
rownames(mycor) <- colnames(mycor)
# display all the correlations
corPrint(mycor)
# only display correlations in magnitude of 0.2 or larger
corPrint(mycor, min_value=.2)
