wordcloud中的空格

我目前使用wordle來進行詞雲的許多藝術用途。我認爲R的詞雲可能有更好的控制。wordcloud中的空格

1）你如何保留一個大寫字雲的詞？ [解決]

2）如何將兩個單詞作爲wordcloud中的一個塊？（wordle使用〜操作符來實現這一點，R的詞雲只是照原樣打印〜）[例如，在「to」和「be」之間有一個〜我想要在詞雲的空間中]

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))

您的原始代碼是可重複的，我根據我對這個問題的答案。您的編輯不再可重複，我的答案不再有意義。 – Andrie

@Andrie對不起，其中一些是自定義函數，我刪除了將來參考 –

你問了兩個問題：

您可以控制資本（或沒有）通過指定控制參數TermDocumentMatrix
毫無疑問，有一種說法某處控制~，但這裏是一個簡單的解決方法：使用gsub更改~在繪圖之前的步驟中對空白區域進行繪製。

一些代碼：

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)

這是一個簡單的修復，我試圖用tm包來處理它，這是不必要的。謝謝。 –
