我只想以文本的形式读取数据框的一个特定列,即第三列c,并创建一个word cloud。让 df=
df=
A B C 1 2 sheep 2 2 sheep 3 4 goat 4 5 camel 5 2 camel 6 1 camel
我试着从 readLines(df$C) 但我得到了以下错误:
readLines(df$C)
Error in readLines(df$C) : 'con' is not a connection
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") ## Package version: 1.3.0 corpus(df, text_field = "C") %>% dfm() %>% textplot_wordcloud(min_count = 1)
