Description

These functions are used to quickly obtain the upper trig, lower trig, diagonal, or remove the diagonal of the correlation coefficient matrix.

Usage

get_lower_data(x, show.diag = TRUE)

get_upper_data(x, show.diag = TRUE)

get_diag_tri(x)

get_diag_data(x)

is_symmet(x)

Arguments

x	a cor_tbl object.
show.diag	a logical value indicating whether keep the diagonal.

Value

a modified cor_tbl object.

Examples

df <- fortify_cor(mtcars)
quickcor(df) + geom_colour()

## exclude upper
df %>% get_lower_data() %>%
  quickcor() + geom_colour()

## exclude lower
df %>% get_upper_data(show.diag = FALSE) %>%
  quickcor() + geom_colour()

## get the diagonal
df %>% get_diag_data() %>%
  quickcor() + geom_colour()

## exclude the diagonal
df %>% get_diag_tri() %>%
  quickcor() + geom_colour()
