Description Usage Arguments Details Value Author(s) Examples
Similar to 'table' function, this function builts a contingency table of the counts at each combination of all possible values from two integer-valued input vectors.
1 | groupcount(g1, g2, n1, n2)
|
g1 |
The first integer-valued input vector. The max value in g1 is n1. |
g2 |
The second integer-valued input vector. The max value in g1 is n2. |
n1 |
The maximum value in g1. |
n2 |
The maximum value in g2. |
This is implemented as an utility function to build a 2D histogram count table. For efficiency, it does not check if the maximum values in input vectors exceed the maximum values specified.
The count table.

g1 <- sample.int(n1,1000, replace = TRUE)
g2 <- sample.int(n2,1000, replace = TRUE)
counts <- groupcount(g1,g2,n1,n2)
