Return the first or last part of a dfm
Description
For a dfm object, return the dfm with only the first or last n
documents.
Usage
## S3 method for class 'dfm'
head(x, n = 6L, ...)
## S3 method for class 'dfm'
tail(x, n = 6L, ...)
Arguments
x |
a dfm object
|
n |
an integer vector of length up to dim(x) (or 1,
for non-dimensioned objects). A logical is silently coerced to
integer. Values specify the indices to be
selected in the corresponding dimension (or along the length) of the
object. A positive value of n[i] includes the first/last
n[i] indices in that dimension, while a negative value
excludes the last/first abs(n[i]) , including all remaining
indices. NA or non-specified values (when length(n) <
length(dim(x)) ) select all indices in that dimension. Must
contain at least one non-missing value.

arguments to be passed to or from other methods.

Value
A dfm class object corresponding to the subset of documents
determined by by n
.
