table

Hello List,

I am trying to obtain a table containing absolute and relative  
frequencies but it must be done by strata. Each strata have to contain  
totals and subtotals being the sum of the subtotals equal to the total  
in upper strata in same column. As this could be some vague I am  
including an example of such table:


data<-data.frame(Provincial=rep(c("Prov1","Prov2","Prov1","Prov3"),10),  
Municipios=rep(c("Mun1","Mun2","Mun3","Mun4"),10),unit=rep(c("unit1","unit2","unit3","unit4"),10))

Variable 	N	%
Province (i)
Municipalities (j)
Health units (k)
&#8721;i,  &#8721;j, &#8721;k
And so on 
 i = 1 to 16

&#8721;i,  &#8721;j, &#8721;k

If you could help me to obtain a function to get such table I would  
appreciate very much.

Best and thank you
.

Hi maicel,
This may be completely off the mark, but the brkdnNest function in the
plotrix package can produce a nested list of counts which can be
transformed into percents (100*count/total).

require(plotrix)
data$dummy<-1
brkdnNest(dummy~Provincial+Municipios+unit,data,FUN="sum")

The counts in your example are mostly NA as most cells are empty.

I suspect that the tabular function in the tables package would handle this task.

Hi Jeff,
I don't have that package, but reading the documentation, I think you are
right. Plus the tabular function already has the formatting worked out.
