Subject: [R] another basic ?
i am sure that there is a simple solution that i am just overlooking, but
there is no logical test for =
there is one for != and >,<, >=, <=...
what do i do if i need to check if something IS EQUAL
or is there an easy way, in working with a matrix of size n x 3, to sort
the matrix by one of the columns?
specifically what i am trying to do is i have a matrix with individual and
group labels that is randomly generated, and is by default sorted by the
individual labels ( column 1) and i want them to be organized into unique
group labels (comlumn 2)
thanks
jimi
