Show Cluster Contents
Description
Show all documents and their non-zero terms in a cluster, with the terms first ordered by highest number of documents the term appears in, then total frequency.
Usage
showCluster(tdm, clust, cl, n = 10L)
Arguments
tdm |
A term frequency matrix. |
clust |
A vector indicating for each column in |
cl |
Cluster number |
n |
Integer showing the maximum number of terms to be returned (default 10) |
Value
A matrix with document names of tdm on the columns and terms
on the rows for all columns in the cluster, where terms that appear in the
most documents (columns), and within that have the highest frequency in the
cluster, are shown first. Two columns are added at the end of the matrix
with the the number of documents each term appears in and its total frequency
in the cluster. The number of terms displayed equals the number in n,
or less if there are less terms in the cluster.
If there are no terms at all in the cluster, a list is output with the items
docs and note, where docs is a vector with all document names of documents in
the cluster, and the note stating that the cluster has no terms.
Examples
M=matrix(c(0,1,0,2,0,10,0,14,12,0,8,0,1,0,1,0),4)
colnames(M)=1:4;rownames(M)=c("A","B","C","D")
tc=textCluster(M,2)
showCluster(M,tc$cluster,1)
