fill in table names

["Crawford.Winnie" <crawford.winnie@ensco.com>]

All,

 

I am running S-PLUS 8 on a Windows XP PC.

 

I have data that I want to table to find the number of lightning occurrences per hour, even if it is 0. If no lightning occurred during a certain hour, the hour is not in the data frame. The table() function only outputs names for the hours that are in the data frame, e.g.

 

>table(dataframe$Hour) yields

 

  0     1     2    3    4   6   9   11   12   13   14   15   16    17    18   19    20   21    22    23

152  97  29  15  3    1   1    2     9    15    14   21   31   45    60   72    98  158  201  225

 

This shows there were no lightning strikes at 5:00, 7:00, 8:00 and 10:00. How can I get 5, 7, 8, and 10 to show up in the table with values of 0 associated with them? Thanks for the help.
