  word_count = 50,
  known_bigrams = c("working group")
)

Value

dataframe of one column (named 'word') that can be used for word cloud creation. One row per bigram supplied in `known_bigrams` or single word (not including "stop words")

Arguments

data

dataframe containing at least one column

text_column

character, name of column in dataframe given to `data` that contains the text to be mined

word_count

known_bigrams

character vector, all bigrams (two-word phrases) to be mined before mining for single words

Examples

# Create a dataframe containing some example text
text <- data.frame(article_num = 1:6,
                   article_title = c("Why pigeons are the best birds",
                                     "10 ways to show your pet budgie love",

# Prepare the dataframe for word cloud plotting              
word_cloud_prep(data = text, text_column = "article_title")

# Plot the word cloud
word_cloud_plot(data = text, text_column = "article_title")
