Faster row-bind for SnpMatrix objects with differing columns

Source: R/utils_geno.R

Combines multiple SnpMatrix objects by rows, automatically handling differing SNP columns, optimized for large matrices.

rbindSnpFlexible(...)

Arguments

...

One or more SnpMatrix objects.

Value

A single SnpMatrix object with all rows combined.

Examples

m1 <- methods::new("SnpMatrix",
                   matrix(as.raw(1:3), nrow = 2, ncol = 3,
                          dimnames = list(c("S1", "S2"),
                                          c("SNP1", "SNP2", "SNP3"))))
m2 <- methods::new("SnpMatrix",
                   matrix(as.raw(1:3), nrow = 2, ncol = 2,
                          dimnames = list(c("S3", "S4"),
                                          c("SNP2", "SNP4"))))
