R help - Dec 2005 - how to extract row& col names from a matrix

Dear all,
  I like to extract row names & column names from the named matrix......
   
  like......
   
   a<-matrix(1:6,2)
 ro<-c("aa","bb")
 co<-c("dd","ee","ff")
 dimnames(a)<-list(ro,co)
a
  
 >
    dd ee ff
aa  1  3  5
bb  2  4  6
   
  from the above matrix "a"
  I like to extract
  rownames separately like rownames(a)= (aa,bb)
    column names separately like col names(a)= (dd,ee,ff)
   
  Kindly suggest me some good ways.......

You mean somthing like the following?
cat("(");cat(rownames(a),sep=",");cat(")")
cat("(");cat(colnames(a),sep=",");cat(")")

Best regrads,

rn = rownames(a);
cn = colnames(a);
