结合两个角色向量

Question

我想结合字符类的两个对象（type_1和type_2）。

type_1

[1] "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1"
   [9] "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1" "FSV1_3h_s1"

type_2

[1] "E14_5_AAACCCAAGAGGCTGT" "E14_5_AAACCCACAAATGATG" "E14_5_AAACCCACAAGGCGTA" "E14_5_AAACCCACATCGGCCA"
   [5] "E14_5_AAACCCAGTTAATGAG" "E14_5_AAACCCATCAACCTTT" "E14_5_AAACCCATCCGCAAAT" "E14_5_AAACCCATCTCCCATG"
   [9] "E14_5_AAACCCATCTTCCACG" "E14_5_AAACGAAAGGAGAGTA" "E14_5_AAACGAAAGGCGAACT" "E14_5_AAACGAAAGTAACGTA"
  [13] "E14_5_AAACGAACAAACTAGA" "E14_5_AAACGAACAATTGAAG" "E14_5_AAACGAACACGACAGA" "E14_5_AAACGAACATAGGCGA"

让您说type_1具有16个值，type_2具有20个。我想创建一个总共包含36个的字符向量。
