psum: Pairwise sum
In raredd/trainr: Analysis project and presentation.

Compute the pairwise sum of two or more vectors

1	psum(..., na.rm = FALSE)

`...`	numeric vectors
`na.rm`	logical; if `TRUE`, omits missing values (including `NaN`) from calculations

Each vector passed in ... must be equal in length. The function coerces the vectors into a matrix and rowSums the rows.

A single vector of element-wise sums.

x <- c(-1, NA, 4, 5)
y <- c(NA, NA, 6, -1)

psum(x, y)
psum(x, y, na.rm = TRUE)
