word_length: Count of Word Lengths Type

In trinker/qdap: Bridging the Gap Between Qualitative Data and Quantitative Analysis

Description

Transcript apply word length counts.

Usage

word_length(
  text.var,
  grouping.var = NULL,
  percent = TRUE,
  zero.replace = 0,
  digits = 2,
  ...
)

Arguments

text.var	The text variable.
grouping.var	The grouping variables. Default NULL generates one word list for all text. Also takes a single grouping variable or a list of 1 or more grouping variables.
percent	logical. If TRUE output given as percent. If FALSE the output is proportion.
zero.replace	Value to replace 0 values with.
digits	Integer; number of decimal places to round when printing.
...	Other arguments passed to bag_o_words.

Value

Returns a list of:

count	Dataframe of word length counts by grouping variable(s).
prop	Dataframe of the proportions of word length counts by grouping variable.
rnp	Dataframe of the frequency and proportions of word length counts by grouping variable.
percent	The value of percent used for plotting purposes.
zero.replace	The value of zero.replace used for plotting purposes.

Examples

## Not run: 
(x <- with(DATA, word_length(state, person)))
plot(x)
scores(x)
proportions(x)
counts(x)
plot(scores(x))
plot(proportions(x))
plot(counts(x))

(x2 <- word_length(DATA[["state"]]))
(x2 <- word_length(DATA[["state"]], apostrophe.remove=TRUE))

## Example Visualizations with Presidential Debate Data
library(tidyr)
(x_long <- proportions(x) %>% 
    gather("Letter_Length", "Proportion", -c(1:2)))
ggplot(x_long, aes(x = Letter_Length, y = Proportion, color=person, group=person)) +
    geom_line(size=.8)


(x3 <- with(pres_debates2012, word_length(dialogue, person)))
(x_long2 <- proportions(x3) %>% 
    gather("Letter_Length", "Proportion", -c(1:2)))
ggplot(x_long, aes(x = Letter_Length, weight = Proportion, fill=person, group=person)) +
    geom_bar()

ggplot(x_long, aes(x = Letter_Length, weight = Proportion, fill=person)) +
    geom_bar() + 
    facet_wrap(~person, ncol=1)
        
ggplot(x_long, aes(x = Letter_Length, weight = Proportion, fill=person)) +
    geom_bar() + 
    coord_flip() + 
    facet_wrap(~person, ncol=1)

ggplot(x_long, aes(x = person, weight = Proportion)) +
    geom_bar(fill="grey40") + 
    coord_flip() + 
    facet_grid(Letter_Length~.)
