R语言数据挖掘：词云的绘制

最近的作业是用爬虫扒数据，自己探索做分析。
今天先把项目的文字云素材部分分享一下。

if (!require(devtools)) install.packages('devtools')
devtools::install_github("lchiffon/wordcloud2",force = TRUE)

报错：没有htmltools包
找了网上的教程，修改为：

ibrary(RCurl)
library(httr)
set_config( config( ssl_verifypeer = 0L ) )

if (!require(devtools)) install.packages('devtools')
devtools::install_github("lchiffon/wordcloud2",force = TRUE)

载入成功。

library(wordcloud2)
wordcloud2(demoFreq,size = 1,shape='star')
wordcloud2(demoFreqC,size = 2, fontFamily = "微软雅黑",
           color = "random-light",background = "grey")

报错：不存在“yaml”程序包

install.packages("yaml")
library(yaml)

完整代码

library(RCurl)
library(httr)
set_config( config( ssl_verifypeer = 0L ) )

if (!require(devtools)) install.packages('devtools')
devtools::install_github("lchiffon/wordcloud2",force = TRUE)


install.packages("yaml")
library(yaml)

library(wordcloud2)
wordcloud2(demoFreq,size = 1,shape='star')
wordcloud2(demoFreqC,size = 2, fontFamily = "微软雅黑",
           color = "random-light",background = "grey")

data <- read.csv('D:/数据/高考.csv',sep=",",header = T)
wordcloud2(data, size = 1, shape='round',color = 'random-light',  
           backgroundColor = "grey",fontFamily = "微软雅黑")
