format_sparsity: format a sparsity value for printing

In koheiw/quanteda.core: Quantitative Analysis of Textual Data

Description

Inputs a dfm sparsity value from sparsity() and formats it for printing in print.dfm().

Usage

format_sparsity(x, threshold = 0.01, digits = 3, nsmall = 1)

Arguments

x	input sparsity value, ranging from 0 to 1.0
threshold	value below which the decimal places will be rounded and printed with an inequality
digits	digits input to format()
nsmall	nsmall input to format()

Value

character value for inserting into the dfm print output

Examples

s <- c(.9, .99, .999, .9999, .99999, 
       .1, .01, .001, .0001, .000001, .0000001, .00000001, .000000000001, 
       sparsity(dfm(data_corpus_inaugural)),
       .12312431242134)
for (i in s) 
    print(paste0(format(i, width = 10),  ":  ", quanteda.core:::format_sparsity(i)))
print(as.dfm(Matrix::rsparsematrix(1000, 1000, density = 0.9999)))
print(as.dfm(Matrix::rsparsematrix(10000, 10000, density = 0.00001)))
