To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

The plural of anecdote is not data.

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

Onderwerp: [R] sorting matrix for rownames

hi members,

i tried to sort my whole matrix X for its rownames. the rownames are 
unsorted id numbers:

i tried it with sort(rownames(X)) or order(rownames(X)) but  then i get 
only a vector of the rownames:(...

any suggestions?

thanks
paul
