【问题描述】:
我的同事萨曼莎问了一个不清楚的问题,所以我在这里问这个问题。
她有一个变量goterms,包含所有要分析的数据帧。
goterms <- c('df1','df2','df3')
interestedGO 变量为每个 goterm 包含一个带有 ILMN 编号的列表。所以第一个列表包含df1 ans等的ILMN代码。
df1 <- c("ILMN_1665132", "ILMN_1691487", "ILMN_1716446", "ILMN_1769383",
"ILMN_1772387", "ILMN_1783910", "ILMN_1784863")
df2 <- c("ILMN_1651599", "ILMN_1652693", "ILMN_1652825", "ILMN_1653324",
"ILMN_1655595", "ILMN_1656057", "ILMN_1659077", "ILMN_1659923",
"ILMN_1659947", "ILMN_1662322", "ILMN_1662619", "ILMN_1664565",
"ILMN_1665132", "ILMN_1665738", "ILMN_1665859")
df3 <- c("ILMN_1661695", "ILMN_1665132", "ILMN_1716446", "ILMN_1737314",
"ILMN_1772387", "ILMN_1784863", "ILMN_1796094", "ILMN_1800317",
"ILMN_1800512", "ILMN_1807074")
interestedGO <- list(df1,df2,df3)
xx2 是一个比较集。 xx2 变量包含所有可能的 ILMN 编号的子集。
xx2 <- c("ILMN_1691487", "ILMN_1716446", "ILMN_1769383","ILMN_1832921")
x 是一种参考集。 x 变量包含所有可能的 ILMN 编号。
x <- c("ILMN_1665132", "ILMN_1691487", "ILMN_1716446", "ILMN_1769383", "ILMN_1772387",
"ILMN_1783910", "ILMN_1784863","ILMN_1651599", "ILMN_1652693", "ILMN_1652825",
"ILMN_1653324", "ILMN_1655595","ILMN_1656057", "ILMN_1659077", "ILMN_1659923",
"ILMN_1659947", "ILMN_1662322","ILMN_1662619", "ILMN_1664565", "ILMN_1665132",
"ILMN_1665738", "ILMN_1665859","ILMN_1661695", "ILMN_1665132", "ILMN_1716446",
"ILMN_1737314", "ILMN_1772387","ILMN_1784863", "ILMN_1796094", "ILMN_1800317",
"ILMN_1800512", "ILMN_1807074")
使用所有这些变量,目标是检查每个 goterm 与相应的 ILMN 代码是否在参考集 xx2 中。为了检查这一点,使用了 match 函数,所有没有匹配的都给出 0,匹配的值被替换为 1。为了方便地概述所有 goterms 实验,我想创建一个如下所示的循环,即检查它的每个基因是否在参考集x 中。最终结果必须是data.frame,它比较data.frame 中每个goterm 的结果。
test <- list()
for (i in 1:length(goterms)) {
goilmn <- as.data.frame(interestedGO[i])
resultILMN <- match(goilmn[,1], xx2, nomatch=0)
resultILMN[resultILMN!=0] <- 1
result <- cbind(goilmn, resultILMN)
colnames(result) <- c('x', 'result')
zz <- merge(result, x, all=TRUE)
zz[is.na(zz)] <- 0
test[[i]] <- matrix(resultloop)
}
最终的输出会是这样的:
1 ILMN_1651599 0 0 0
2 ILMN_1652693 0 0 0
3 ILMN_1652825 0 0 0
4 ILMN_1653324 0 0 0

13 ILMN_1664565 0 0 0
14 ILMN_1665132 0 0 0
15 ILMN_1665132 0 0 0
16 ILMN_1665132 0 0 0
17 ILMN_1665738 0 0 0

19 ILMN_1691487 0 0 1
20 ILMN_1716446 1 0 1
21 ILMN_1716446 1 0 1
22 ILMN_1737314 0 0 0
23 ILMN_1769383 0 0 1
24 ILMN_1772387 0 0 0
25 ILMN_1772387 0 0 0
26 ILMN_1783910 0 0 0
27 ILMN_1784863 0 0 0
28 ILMN_1784863 0 0 0
29 ILMN_1796094 0 0 0
30 ILMN_1800317 0 0 0
31 ILMN_1800512 0 0 0
32 ILMN_1807074 0 0 0
谁能帮我解决这个问题? 谢谢!
