## S3 method for class 'vocabularyComparison'
plot(
x,
n = 25,
mode = c("both", "ratio_x", "ratio_y"),
balance = T,
size = c("chi2", "freq", "ratio"),
...
)x |
a vocabularyComparison object, created with the compare_corpus or compare_subset method |
n |
the number of words in the plot |
mode |
use "both" to plot both overrepresented and underrepresented words using the plot_words function. Whether a term is under- or overrepresented is indicated on the x-axis, which shows the log ratios (negative is underrepresented, positive is overrepresented). Use "ratio_x" or "ratio_y" to only plot overrepresented or underrepresented words using dtm_wordcloud |
balance |
if TRUE, get an equal amount of terms on the left (underrepresented) and right (overrepresented) side. If FALSE, the top chi words are used, regardless of ratio. |
size |
use "freq", "chi2" or "ratio" for determining the size of words |
... |
additional arguments passed to plot_words ("both" mode) or dtm_wordcloud (ratio modes) |
## as example, compare SOTU paragraphs about taxes to rest tc = create_tcorpus(sotu_texts[1:100,], doc_column = 'id') comp = compare_subset(tc, 'token', query_x = 'tax*') plot(comp, balance=TRUE) plot(comp, mode = 'ratio_x') plot(comp, mode = 'ratio_y')
