Dear all, I have a vector like this:
z = rep(c(M,F),c(50,60))
How can I get the following frequency table:
Sex counts %
F60 54.5
M 50 45.5
I try:
DD- function(data,...)
{
n - nobs(data)
out - c(Frequency
And look at ?prop.table too.

You might want to look at the CrossTable function in the gmodels
package (in the gregmisc bundle).

Hi,
See if this generic function I made can help you.
data - c(65, 70, 85, 65, 65, 65, 62, 55, 82, 59,
55, 66, 74, 55, 65, 56, 80, 73, 45, 64,
75, 58, 60, 56, 60, 65, 53, 63, 72, 80,
90, 95, 55, 70, 79, 62, 57, 65, 60, 47,
61, 53, 80,
This must be FAQ, but I can't find it in archives or with a site search.
I am trying to construct a frequency table. I guess this should be done with
table. Or perhaps factor and split. Or prop.table. cut? findInterval? Argh!
Please correct me if what I am looking for is not called a frequency
I guess you want something like:
table(cut(zz$x9, c(-Inf, seq(40, 90, by=10), Inf)))

I got this far:

Here's another solution for this 10-year age group thing:
tt-table(zz%/%10)
n - names(tt)
names(tt) - paste(n,0,-,n,9,sep=)
tt
data.frame(count=c(tt))
Beware that empty groups are

Beware that empty groups are silently zapped, though.
FWIW, table(factor(zz%/%10, levels=0:9)) avoids that

A neat trick with table() is that you can use it to tabulate
columns of a matrix (for example) with:
apply(mymatrix,2,table)
OK, I'll bite:
x1 - matrix(1:3,7,4,byrow=T)
