plot.correlate: Visualize Information for an "correlate" Object

Description

Visualize by attribute of `correlate` class. The plot of correlation matrix is a tile plot.

Usage

# S3 method for correlate
plot(x, typographic = TRUE, base_family = NULL, ...)

Value

No return value. This function is called for its side effect, which is to produce a plot on the current graphics device.

Arguments

x: an object of class "correlate", usually, a result of a call to correlate().
typographic: logical. Whether to apply focuses on typographic elements to ggplot2 visualization. The default is TRUE. if TRUE provides a base theme that focuses on typographic elements using hrbrthemes package.
base_family: character. The name of the base font family to use for the visualization. If not specified, the font defined in dlookr is applied. (See details)
...: arguments to be passed to methods, such as graphical parameters (see par).

Details

The base_family is selected from "Roboto Condensed", "Liberation Sans Narrow", "NanumSquare", "Noto Sans Korean". If you want to use a different font, use it after loading the Google font with import_google_font().

Examples

Run this code

# \donttest{
library(dplyr)

# correlate type is generic ==================================
tab_corr <- correlate(iris)
tab_corr

# visualize correlate class 
plot(tab_corr)

tab_corr <- iris %>% 
  correlate(Sepal.Length, Petal.Length)
tab_corr

# visualize correlate class 
plot(tab_corr)

# correlate type is group ====================================
# Draw a correlation matrix plot by category of Species.
tab_corr <- iris %>% 
  group_by(Species) %>% 
  correlate()

# plot correlate class
plot(tab_corr)

## S3 method for correlate class by 'tbl_dbi' ================
# If you have the 'DBI' and 'RSQLite' packages installed, perform the code block:
if (FALSE) {
# connect DBMS
con_sqlite <- DBI::dbConnect(RSQLite::SQLite(), ":memory:")

# copy iris to the DBMS with a table named TB_IRIS
copy_to(con_sqlite, iris, name = "TB_IRIS", overwrite = TRUE)

# correlation coefficients of all numerical variables
tab_corr <- con_sqlite %>% 
   tbl("TB_IRIS") %>% 
   correlate()
   
plot(tab_corr)   
   
# Disconnect DBMS   
DBI::dbDisconnect(con_sqlite)
}
# }
