'Get match and order two lists based on the elements' name in R

I need to get matched the two lists, list_1 and list_2 and also get them in order based on elements' name. In fact, I want to remove the elements, those are not common between two lists. I do not want to consider any difference in their nested lists. The desired outputs are two lists including the only elements whose exist in both lists. Both have same structure.

list_1 <- list(ENSG0000014 = structure(list(name = c("E-1122O", "E-11EM3", 
"E-11EMC", "E-1442O", "E-1132O"), ENSG = c("ENSG0000014", "ENSG0000014", 
"ENSG0000014", "ENSG0000014", "ENSG0000014"), expr = c(" 9.940670e-02", 
" 1.289670e-01", "-7.394904e-03", " 9.940670e-02", " 9.940670e-02"
), `1_43222779_A_G_b37` = c("1", "1", "2", "1", "0"), `1_43222856_A_G_b37` = c("0",

-5L), class = c("tbl_df", "tbl", "data.frame")), ENSG0000015 = structure(list(
    name = c("E-1122O", "E-11EM3", "E-11EMC", "E-1442O", "E-1132O"
    ), ENSG = c("ENSG0000015", "ENSG0000015", "ENSG0000015", 
    "ENSG0000015", "ENSG0000015"), expr = c(" 9.940670e-02",

Solution 1:[1]

We get the intersecting names from both lists and then use that to subset the list

nm1 <- intersect(names(list_1), names(list_2))
list_1_new <- list_1[nm1]
list_2_new <- list_2[nm1]
