x: This represents the vector source for combinations.m: This represents the number of elements to choose from thexobject.
Return value
The combn() function returns a list or an array.
Code example
# creating the vector sourcex <- c('A', 'B', 'C', 'D', 'E')# implementing the combn() function for diferent number of elementscombn(x, 1)combn(x, 2)combn(x, 3)
Code explanation
- Line 2: We create a vector source
x. - Lines 5–7: We implement the
combn()function, using different numbers of elements to choose from the vector objectx.
