Title
Body
I have an R object called gene_table, and it has class foo . Now I subset this gene_table by gene_data = gene_table[1:100,1:5] However, when I call class(gene_data) , it is no longer of class foo , but instead, it has class matrix . This is a headache for me because my method summary.foo won't recognize this object gene_data of class matrix. I am hoping to retain the original class attribute when subsetting, so could anyone tell me how to do it? Thanks! Update: dput(head(gene_table)) gives me c(5.21708054951994, 5.01224214039806, 4.92160314073853, 4.83031021496, 4.78552614584879, 4.77821370665578) and str(gene_table) gives me foo [1:22743, 1:2] 5.22 5.01 4.92 4.83 4.79 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:22743] "ENSG00000127954" "ENSG00000151503" "ENSG00000096060" "ENSG00000091879" ... ..$ : chr [1:2] "Var1" "Var2"
