a numerical coefficient to adjust the rows selection rule ; see the details section.
a numerical coefficient to adjust the columns selection rule ; see the details section.
the text label to add before graph title.
a boolean : if TRUE, graphs are plotted.
an optional argument for the generic plot functions, used to adjust the size of the elements plotted.
a character string corresponding to the code to use for the CA graph.

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

The Rselec argument (respectively Cselec) is used in order to select a part of the elements that are drawn and described. For example, you can use either :
- Rselec = 1:5 then the rows (the columns) numbered 1 to 5 are drawn.
- Rselec = c("name1","name5") and then the rows (the columns) named name1 and name5 are drawn.
- Rselec = "contrib 10" then the 10 active or illustrative rows (the columns) that have the highest contribution on the 2 dimensions of the plane are drawn.
- Rselec = "contrib" then the optimal number of active or illustrative rows (the columns) that have the highest contribution on the 2 dimensions of the plane are drawn.
- Rselec = "cos2 5" then the 5 active or illustrative rows (the columns) that have the highest cos2 on the 2 dimensions of the plane are drawn.
- Rselec = "cos2 0.8" then the active or illustrative rows (the columns) that have a cos2 higher to 0.8 on the plane are drawn.
- Rselec = "cos2" then the optimal number of active or illustrative rows (the columns) that have the highest cos2 on the 2 dimensions of the plane are drawn.
The Rcoef argument (respectively Ccoef) is used in order to adjust the selection of the elements when based on Rselec = "contrib" or Rselec = "cos2". For example :
- if Rcoef = 2, the threshold is 2 times higher, and thus 2 times more restrictive.
- if Rcoef = 0.5, the threshold is 2 times lower, and thus 2 times less restrictive.
