Hello,

I'm trying to make a table like windfreq.dat in the rose diagram example of
the climatol package.
It looks like:
          N  NNE   NE  ENE    E  ESE   SE  SSE    S  SSW   SW  WSW    W
WNW   NW  NNW
0-3     59   48     75   90      71   15     10   11     14   20       22
  22       24   15        19    33
3-6      3    6       29   42       11    3       4    3       9   50
67     28       14   13        15    5
6-9      1    3       16   17        2     0       0    0       2   16
  33    17          6    5           9    2
"> 9"    0    1         2    3          0    0       0    0       0
1            4    3           1    1           2    0

Each row is the number of observations for a given wind direction (i.e. N,
NNE, NE, etc.) is within the limits of the specified speed (i.e. 0-3, 3-6,
etc.).

I have a table with 2 fields - *direction values* (0-36, which represents
the direction/10) and *speed values*.

I can use the direction values to get a 1-dimensional array of the frequency
of each direction value using:

Wind_freq <- table(cut(Wind_Dir_vec, 0:36))
Wind_freq_t <- t(Wind_freq)      ## transpose it to be in the same format as
the data above

but I need to incorporate the speed values and have a table like the
following:

                 1     2     3     4     5     6 .... 36
0-9
10-19
20-29
30-39
40-49
50+

The final table will be used in the rosavent function to produce a wind rose
diagram just like in this example:

Anyone have any ideas.  Thanks.
