我有两个维度为6的向量，我希望得到一个介于0和1之间的数值。

a=c("HDa","2Pb","2","BxU","BuQ","Bve")b=c("HCK","2Pb","2","09","F","G")

谁能解释一下我应该怎么做？

回答：

使用lsa包及其手册

# 创建一些文件library('lsa')td = tempfile()dir.create(td)write( c("HDa","2Pb","2","BxU","BuQ","Bve"), file=paste(td, "D1", sep="/"))write( c("HCK","2Pb","2","09","F","G"), file=paste(td, "D2", sep="/"))# 将文件读入文档-词矩阵myMatrix = textmatrix(td, minWordLength=1)

编辑：展示mymatrix对象的结构
