Correspondence Analysis (CA)
Performs Correspondence Analysis (CA) including supplementary row and/or column points.
CA( d, ncp = 5, row.sup = NULL, col.sup = NULL, quanti.sup = NULL, quali.sup = NULL, row.w = NULL )
d |
A ddata frame or a table with n rows and p columns, i.e. a contingency table. |
ncp |
The number of dimensions kept in the results (by default 5). |
row.sup |
A vector indicating the indexes of the supplementary rows. |
col.sup |
A vector indicating the indexes of the supplementary columns. |
quanti.sup |
A vector indicating the indexes of the supplementary continuous variables. |
quali.sup |
A vector indicating the indexes of the categorical supplementary variables. |
row.w |
An optional row weights (by default, a vector of 1 for uniform row weights); the weights are given only for the active individuals. |
The CA on the dataset.
data (children, package = "FactoMineR") CA (children, row.sup = 15:18, col.sup = 6:8)
