graphSup {FactoInvestigate}

Supplementary variables factor map

Description

Realise the optimised graph of supplementary variables

Usage

graphSup(res, file = "", dim = 1:2, Mselec = "cos2", Mcoef = 1, 
         figure.title = "Figure", graph = TRUE, cex = 0.7, options=NULL)

Arguments

res

an object of class PCA, CA or MCA.

file

the file path where to write the description in Rmarkdown language. If not specified, the description is written in the console.

dim

a 2 dimensional numerical vector giving the factorial dimensions to use for the representation (by default the first plane).

Mselec

the supplementary variables to select ; see the details section.

Mcoef

a numerical coefficient to adjust the supplementary variables selection rule ; see the details section.

figure.title

the text label to add before graph title.

graph

a boolean : if TRUE, graphs are plotted.

cex

an optional argument for the generic plot functions, used to adjust the size of the elements plotted.

options

a character string that gives the output options fir the figures. If NULL, options="r, echo = FALSE, fig.align = 'center', fig.height = 3.5, fig.width = 5.5" for linux and Mac and options="r, echo = FALSE, fig.height = 3.5, fig.width = 5.5" for Windows

Details

The Mselec argument is used in order to select a part of the illustrative variables that are drawn and described. For example, you can use either :
- Mselec = 1:5 then the illustrative variables numbered 1 to 5 are drawn.
- Mselec = c("name1","name5") then the illustrative variables named name1 and name5 are drawn.
- Mselec = "cos2 5" then the 5 illustrative variables that have the highest cos2 on the 2 dimensions of the plane are drawn.
- Mselec = "cos2 0.8" then the illustrative variables that have a cos2 higher to 0.8 on the plane are drawn.
- Mselec = "cos2" then the optimal number of illustrative variables that have the highest cos2 on the 2 dimensions of the plane are drawn.

The Mcoef argument is used in order to adjust the selection of the illustrative variables when based on Mselec = "cos2". For example :
- if Mcoef = 2, the threshold is 2 times higher, and thus 2 times more restrictive.
- if Mcoef = 0.5, the threshold is 2 times lower, and thus 2 times less restrictive.
