get_ca {factoextra} | R Documentation |
Extract all the results (coordinates, squared cosine, contributions and inertia)
for the active row/column variables from Correspondence Analysis (CA) outputs.
get_ca(): Extract the results for rows and columns
get_ca_row(): Extract the results for rows only
get_ca_col(): Extract the results for columns only
get_ca(res.ca, element = c("row", "col")) get_ca_col(res.ca) get_ca_row(res.ca)
res.ca |
an object of class CA [FactoMineR], ca [ca], coa [ade4]; correspondence [MASS]. |
element |
the element to subset from the output. Possible values are "row" or "col". |
a list of matrices containing the results for the active rows/columns including :
coord |
coordinates for the rows/columns |
cos2 |
cos2 for the rows/columns |
contrib |
contributions of the rows/columns |
inertia |
inertia of the rows/columns |
