Description

Display a one screen short version of a textmatrix.

Usage

# S3 method for textmatrix

Arguments

x

A textmatrix.

bag_lines

The number of lines per bag.

bag_cols

The number of columns per bag.

…

Arguments to be passed on.

Details

Document-term matrices are often very large and cannot be displayed completely on one screen. Therefore, the textmatrix print method displays only clippings (`bags') from this matrix.

Clippings are taken vertically and horizontally from beginning, middle, and end of the matrix. bag\_lines lines and bag\_cols columns are printed to the screen.

To keep document titles from blowing up the display, the legend is printed below, referencing the symbols used in the table.

Examples

# NOT RUN {
# fake a matrix
m = matrix(ncol=800, nrow=400)
m[1:length(m)] = 1:length(m)
colnames(m) = paste("D",1:ncol(m),sep="")
rownames(m) = paste("W",1:nrow(m),sep="")
class(m) = "textmatrix"

# show a short form of the matrix
print(m, bag_cols=5)

# }
