[R] matrix

[ONKELINX, Thierry]

Split the first column into two columns. One with the first letter and
one with the last letter. Then you cast() from the reshape-package to
create the matrix you want.

HTH,

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.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

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.

Hi  



I have dataset that consists of two columns

AC           -0.002

BC           0.270



CA           0.002



CB          -0.270
