Safe cbind for SnpMatrix preserving dimnames — cbind

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

cbind_SnpMatrix(...)

Arguments

...: SnpMatrix objects to combine (must have identical row names).

Value

A single combined SnpMatrix with preserved row and column names.

Examples

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