Question

I want to read as text only one specific column of my dataframe, i.e. the 3rd column C, and create a word cloud. Let df=

A B C
1 2 sheep
2 2 sheep
3 4 goat
4 5 camel
5 2 camel
6 1 camel

I am try to readLines from readLines(df$C) but I get the following error:

 Error in readLines(df$C) : 
  'con' is not a connection

Answer 1

df <- read.table(textConnection("A B C
1 2 sheep
2 2 sheep
3 4 goat
4 5 camel
5 2 camel
6 1 camel"), header = TRUE, stringsAsFactors = FALSE)

library("quanteda")

corpus(df, text_field = "C") %>%
    dfm() %>%
    textplot_wordcloud(min_count = 1)
