Plot of correlations between variables.

Description

It performs the correlations between the variables of a database and presents it in graph form.

Usage

Plot.Cor(data, title = NA, grid = TRUE, leg = TRUE, boxleg = FALSE, 
         text = FALSE, arrow = TRUE, color = TRUE, namesvar = NA,
         savptc = FALSE, width = 3236, height = 2000, res = 300)

Arguments

data

Numeric data set.

title

Title for the plot, if not defined it assumes standard text.

grid

Puts grid on plot (default = TRUE).

leg

Put the legend on the plot (default = TRUE)

boxleg

Put frame in the legend (default = FALSE).

text

color

Colorful plot (default = TRUE).

namesvar

Vector with the variable names, if omitted it assumes the names in 'date'.

savptc

Saves graphics images to files (default = FALSE).

width

Graphics images width when savptc = TRUE (defaul = 3236).

height

Graphics images height when savptc = TRUE (default = 2000).

res

Nominal resolution in ppi of the graphics images when savptc = TRUE (default = 300).

Value

Plot with the correlations between the variables in 'date'.

data(iris) # data set

Plot.Cor(data = iris[,1:4], title = NA, grid = TRUE, leg = TRUE, boxleg = FALSE, 
         text = FALSE, arrow = TRUE, color = TRUE, namesvar = NA, savptc = FALSE, 
         width = 3236, height = 2000, res = 300)
         
Plot.Cor(data = iris[,1:4], title = NA, grid = TRUE, leg = TRUE, boxleg = FALSE, 
         text = TRUE, arrow = TRUE, color = TRUE, namesvar = c("A1","B2","C3","D4"),
         savptc = FALSE, width = 3236, height = 2000, res = 300)
