Combines correlation coefficients and significance levels in a correlation matrix data.

cor_mark_significant(x, cutpoints = c(0, 1e-04, 0.001, 0.01, 0.05, 1),
  symbols = c("****", "***", "**", "*", ""))

Arguments

x

an object of class cor_mat().

cutpoints

numeric vector used for intervals.

symbols

character vector, one shorter than cutpoints, used as significance symbols.

Value

a data frame containing the lower triangular part of the correlation matrix marked by significance symbols.

Examples

mtcars %>% select(mpg, disp, hp, drat, wt, qsec) %>% cor_mat() %>% cor_mark_significant()
#> rowname mpg disp hp drat wt qsec #> 1 mpg #> 2 disp -0.85**** #> 3 hp -0.78**** 0.79**** #> 4 drat 0.68**** -0.71**** -0.45** #> 5 wt -0.87**** 0.89**** 0.66**** -0.71**** #> 6 qsec 0.42* -0.43* -0.71**** 0.091 -0.17
