)

Arguments

data

Data frame.

method

"pearson" (default), "spearman", or "kendall".

p.adjust

Adjustment of p values for multiple tests: "none", "fdr", "holm", "bonferroni", ... For details, see stats::p.adjust().

all.as.numeric

TRUE (default) or FALSE. Transform all variables into numeric (continuous).

digits, nsmall

Number of decimal places of output. Default is 2.

file

File name of MS Word (.doc).

plot

TRUE (default) or FALSE. Plot the correlation matrix.

plot.range

Range of correlation coefficients for plot. Default is c(-1, 1).

plot.palette

Color gradient for plot. Default is c("#B52127", "white", "#2171B5"). You may also set it to, e.g., c("red", "white", "blue").
