Safe rbind for SnpMatrix preserving dimnames

Source: R/combine.R

This function performs a row-wise binding of multiple SnpMatrix objects, explicitly preserving row names and column names, avoiding unexpected "object has no names" warnings.

rbind_SnpMatrix(...)

Arguments

...

SnpMatrix objects to combine (must have identical column names).

Value

A single combined SnpMatrix with preserved row and column names.

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 = 3,
                          dimnames = list(c("S3", "S4"),
                                          c("SNP1", "SNP2", "SNP3"))))
rbind_SnpMatrix(m1, m2)
