R help - May 2008 - create frequency table

I haven't quite been able to grasp how to use "hist" to create
frequency
tables so I have decided it will be easier to make my own.

I have a list of numeric data, x, from 0 to 30:
x <- sample(0:30, 100)

I've created an object containing the bins I would like frequency counts by:
z <- as.matrix(seq(from=0, to=30, by=1))

I would now like to create a new column in z containing counts of all values
in x less than or equal to [m,1], thereby allowing me to conduct further
modifications.  My intuition tells me this is not that difficult but I lack
the programming prowess.

Does anyone have a solution?

Not list but vector. Besides the above version gives you error. Use

x <- sample(0:30, 100, replace=T)

instead.

Maybe it would be easier to use table function 

table(x)

I am not sure what do you exactly want but maybe

table(x[x<20])
