ktab {ade4} | R Documentation |
an object of class ktab
is a list of data frames with the same row.names in common.
a list of class 'ktab' contains moreover :
c.ktab (...) x[selection] is.ktab(x) t.ktab(x) row.names.ktab(x) col.names.ktab(x) tab.names(x) col.names(x) ktab.util.names(x)
x |
an object of the class ktab |
... |
a sequence of objects of the class ktab |
selection |
an integer vector |
A 'ktab' object can be created with :
a list of data frame : ktab.list.df
a list of dudi
objects : ktab.list.dudi
a data.frame : ktab.data.frame
an object within
: ktab.within
a couple of ktab
s : ktab.match2ktabs
c.ktab
returns an object ktab
. It concatenates K-tables with the same rows in common.
t.ktab
returns an object ktab
. It permutes each data frame into a K-tables. All tables have the same column names and the same column weightings (a data cube).
"["
returns an object ktab
. It allows to select some arrays in a K-tables.
is.ktab
returns TRUE if x is a K-tables.
row.names
returns the vector of the row names common with all the tables of a K-tables and allowes to modifie them.
col.names
returns the vector of the column names of a K-tables and allowes to modifie them.
tab.names
returns the vector of the array names of a K-tables and allowes to modifie them.
ktab.util.names
is a useful function.
