I am trying to construct a two-way table where, instead of printing the
two-way frequencies in the table, I would like to print the values of a
third variable that correspond to the frequencies.
For example, the following is easily constructed in R
fact1 <- factor(sample(LETTERS[1:3],10,replace=TRUE))
fact2 <- factor(sample(LETTERS[25:26],10,replace=TRUE))
fact3 <- letters[1:10]
data.frame(fact1,fact2,fact3)
fact1 fact2 fact3
1 C Z a
2 A Y b
3 A Y c
4 C Z d
5 A Z e
6 A Y f
7 B Y g
8 B Y h
9 C Z i
10 A Y j
table(fact1,fact2)
fact2
fact1 Y Z
A 4 1
B 2 0
C 0 3
But I would like to create something like this (done physically by hand)
...
fact2
fact1 Y Z
A b,c,f,j e
B g,h -
C - a,d,i
Any help would be appreciated. Thank you in advance.
