[R] How Aggegate Data in R

[chao gai]

Having no SPSS I have to resort to deductive inference. It seems that you want 
to make a frequency table of the occurence of these 25 digit strings, hence 
?xtab
?table
spring to mind. I have the faint suspicion that seeing this as 25 variables 
might be less efficient than seeing it as one 25 digit string, but having no 
idea about the purpose or background, that is as far as one may go.
