从列表中提取路径中的特定路径名和基因R
问题描述：
我有一列存储在kegg列表中的路径和基因（对应于每个路径）。我想使用途径ID提取途径中的基因。我该怎么做？从列表中提取路径中的特定路径名和基因R
我的表看起来是
head(kegg2)
$`04610`
[1] "2" "462" "623" "624" "629" "710" "712" "713" "714" "715" "716" "717" "718" "719" "720" "721" "722" "725" "727"

$`00232`
[1] "9" "10" "1544" "1548" "1549" "1553" "7498"
$`00983`
[1] "9" "10" "978" "1066" "1548" "1549" "1551" "1553" "1576" "1577" "1806" "1807" "1890" "2990" "3251" "3614" "3615"
[18] "3704" "7083" "7084" "7172" "7363" "7364" "7365" "7366" "7367" "7371" "7372" "7378" "7498" "8824" "8833" "10720" "10941"

[52] "574537"
所以$后的数字为途径的ID，我想拉出来的基因中使用途径ID的具体途径。例如，我想拔出的基因途径，所以我希望输出像一个列表的
00232 [1] "9" "10" "1544" "1548" "1549" "1553" "7498"

访问内容：
kegg2[["00232"]]
或（请注意使用的反引号`允许使用一个数字作为“名称”）
kegg2$`00232`
