我有下表
structure(list(Compound = structure(c(1L, 2L, 3L, 1L, 1L, 3L), .Label = c("Nap",
"Phe", "tre"), class = "factor"), Area = c(17197669L, 19464754L,
35792660L, 10097291L, 348395L, 2576352L), Samples = structure(c(1L,
1L, 1L, 2L, 3L, 2L), .Label = c("a1", "a2", "a3"), class = "factor")), .Names = c("Compound",
"Area", "Samples"), class = "data.frame", row.names = c(NA, -6L
))
我想重新排序
structure(list(Compound = structure(1:3, .Label = c("Nap", "Phe",
"tre"), class = "factor"), a1 = c(17197669L, 19464754L, 35792660L
), a2 = c(10097291L, 0L, 2576352L), a3 = c(348395L, 0L, 0L)), .Names = c("Compound",
"a1", "a2", "a3"), class = "data.frame", row.names = c(NA, -3L
))
有什么建议吗?我不知道如何开始。
