由于我使用的函数需要一个表对象作为参数,我想将一个多维数组转换为一个表,但我有维度名称的问题.

如帮助文件中所指定as.table,dnn参数应包含dimnames名称.

dnn … the names to be given to the dimensions in the result (the dimnames names).

但即使在指定时dnn,我生成的表as.table也没有维度名称.

以下代码说明了我的问题.

>test <- table(c("a","b","c","c","c"),c("1","2","3","2","2"),dnn=c("letters","numbers"))
>test 

          numbers
letters 1 2 3
      a 1 0 0
      b 0 1 0
      c 0 2 1

# this works perfectly

现在从数组构造表时尝试相同:

>my2dimdata <- array(c(1,0,0,0,1,2,0,0,1),dim=c(3,3),
                    dimnames=list(c("a","b","c"),
                                  c("1","2","3")))
>my2dimdata

  1 2 3
a 1 0 0
b 0 1 0
c 0 2 1

# the array as expected …
