class(data_me) [1] "matrix" "array".
##data_me is not data.frame structure.

Example data:

data(iris)
m <- as.matrix(iris)
rownames(m) <- 1:nrow(m)

Use cbind to add a new column:

g <- cbind(m, rownames(m))

Then add your new column name:

colnames(g) <- c(colnames(m), "GENE_ID")

m <- as.matrix(data_X) > g <- cbind(m, rownames(m)) > rownames(g) [1] "ENSG00000000003" "ENSG00000000005" "ENSG00000000419" "ENSG00000000457" "ENSG00000000460" – YiHao Chen Jul 29 '22 at 13:17
the rowname is still ENSG ,why? i will try again , – YiHao Chen Jul 29 '22 at 13:18
rownames are retained when cbinding. You can use `rownames(g) <- NULL` to remove them – Skaqqs Jul 29 '22 at 16:55
