R可视化——基于wordcloud2包绘制词云图
安装、加载R包
#安装R包install.packages("wordcloud2")#加载R包library(wordcloud2)数据
这里我们使用示例数据：
df1<-demoFreqdf2<-demoFreqC绘图
1、基础绘图
#基础绘图wordcloud2(df, #数据 size=1.5,#字体大小 fontFamily = 'Segoe UI',#字体 fontWeight = 'bold',#字体粗细 color='random-light',#字体颜色设置 backgroundColor="black"#背景颜色设置 )wordcloud2(df2, #数据 size=1.5,#字体大小 fontFamily = 'Segoe UI',#字体 fontWeight = 'bold',#字体粗细 color='random-light',#字体颜色设置 backgroundColor="black"#背景颜色设置 )2、改变词的方向
wordcloud2(df1, size = 2, minRotation = -pi/6, maxRotation = -pi/6,#文本旋转角度范围 rotateRatio = 0.5)#文本选择概率wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'star')#改变形状wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'circle')#改变形状wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'cardioid')#改变形状wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'diamond')#改变形状wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'triangle-forward')#改变形状wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'triangle')#改变形状wordcloud2(df1,size=1.5,color='random-light',backgroundColor="black", shape = 'pentagon')#改变形状我就知道你“在看”
