wordcloud中的空格

Question

我目前使用wordle用于词云的许多艺术用途。我认为R的词云可能具有更好的控制能力。

1）你如何在词云中保留一个词？ [解决]

2）如何在wordcloud中将两个单词保留为一个块？ （wordle使用〜运算符来实现这一点，R的单词云只打印〜原样）[例如，在“to”和“be”之间有一个〜我喜欢单词云中的空格]

require(wordcloud)

y<-c("the", "the", "the", "tree", "tree", "tree", "tree", "tree", 
"tree", "tree", "tree", "tree", "tree", "Wants", "Wants", "Wants", 
"Wants", "Wants", "Wants", "Wants", "Wants", "Wants", "Wants", 
"Wants", "Wants", "to~be", "to~be", "to~be", "to~be", "to~be", 
"to~be", "to~be", "to~be", "to~be", "to~be", "to~be", "to~be", 
"to~be", "to~be", "to~be", "to~be", "to~be", "to~be", "to~be", 
"to~be", "when", "when", "when", "when", "when", "familiar", "familiar", 
"familiar", "familiar", "familiar", "familiar", "familiar", "familiar", 
"familiar", "familiar", "familiar", "familiar", "familiar", "familiar", 
"familiar", "familiar", "familiar", "familiar", "familiar", "familiar", 
"leggings", "leggings", "leggings", "leggings", "leggings", "leggings", 
"leggings", "leggings", "leggings", "leggings")

wordcloud(names(table(y)), table(y))

Answer 1

你问了两个问题：

1. 您可以通过指定TermDocumentMatrix
的控制参数来控制大小写（或不大写）
2. 毫无疑问，有一个论点可以控制~，但这是一个简单的解决方法：在绘图前的步骤中使用gsub将~更改为空格。< / LI>

   一些代码：

   corpus <- Corpus(VectorSource(y))
   tdm <- TermDocumentMatrix(corpus, control=list(tolower=FALSE)) ## Edit 1
   
   m <- as.matrix(tdm)
   v <- sort(rowSums(m), decreasing = TRUE)
   d <- data.frame(word = names(v), freq = v)
   d$word <- gsub("~", " ", d$word) ## Edit 2
   
   wordcloud(d$word, d$freq)
