cat.factor {spatstat.utils} | R Documentation |
Combine (concatenate) several factor objects, to produce a factor.
cat.factor(...)
... |
Any number of arguments. Each argument should be a factor, or will be converted to a factor. |
The arguments ...
are concatenated as they would be
using c()
or cat()
,
except that factor levels are retained
and merged correctly. See the Examples.
A factor, whose length is the sum of the lengths of all arguments. The levels of the resulting factor are the union of the levels of the arguments.
