| ktab.data.frame {ade4} | R Documentation |
creates K tables from a data frame.
ktab.data.frame(df, blocks, rownames = NULL, colnames = NULL,
tabnames = NULL, w.row = rep(1, nrow(df)) / nrow(df),
w.col = rep(1, ncol(df)))
df |
a data frame |
blocks |
an integer vector for which the sum must be the number of variables of df. Its length is the number of arrays of the K-tables |
rownames |
the row names of the K-tables (otherwise the row names of df) |
colnames |
the column names of the K-tables (otherwise the column names of df) |
tabnames |
the names of the arrays of the K-tables (otherwise "Ana1", "Ana2", ...) |
w.row |
a vector of the row weightings |
w.col |
a vector of the column weightings |
returns a list of class ktab. See ktab.
