哪一組符合標(biāo)準(zhǔn)a<b<c取決于條件

我的標(biāo)題可能信息量不大，但這是一個(gè)暴露我問(wèn)題的例子：

我有這個(gè)數(shù)據(jù)框：

df=data.frame(cond1=c(1,1,1,2,2,2,3,3,3,1,1,1,2,2,2,3,3,3),
              group=c("F","V","M","F","V","M","F","V","M","F","V","M","F","V","M","F","V","M"),
              gene=c("A","A","A","A","A","A","A","A","A","B","B","B","B","B","B","B","B","B"),
              value=c(1,2,3,4,5,6,7,8,9,1,3,2,4,3,2,2,3,4))
df
       cond1 group gene value
    1      1     F    A     1
    2      1     V    A     2
    3      1     M    A     3
    4      2     F    A     4
    5      2     V    A     5
    6      2     M    A     6
    7      3     F    A     7
    8      3     V    A     8
    9      3     M    A     9
    10     1     F    B     1
    11     1     V    B     3
    12     1     M    B     2
    13     2     F    B     4
    14     2     V    B     3
    15     2     M    B     2
    16     3     F    B     2
    17     3     V    B     3
    18     3     M    B     4

我想得到的是，對(duì)于每個(gè)基因，有多少不同的cond1的值對(duì)應(yīng)于F組，小于它們對(duì)應(yīng)于V的值，它們對(duì)應(yīng)于M的值。

在前三個(gè)品系中，我們的第二個(gè)基因是A。對(duì)應(yīng)于組F=1、V=2、M=3的值。因此，對(duì)于cond1=1組的A基因，F(xiàn)<V<M。

我對(duì)基因A的預(yù)期輸出是3，因?yàn)樗衏ond1組的值都滿足F<V<M。我對(duì)基因B的預(yù)期輸出是1，因?yàn)橹挥衏ond1=3組的值符合F<V<M。

理想情況下，我希望的輸出是一個(gè)數(shù)據(jù)幀，其中包含gene和cond1之和，不滿足我的標(biāo)準(zhǔn)：

  gene count
1    A     3
2    B     1

如果你能給我一些建議，告訴我該怎么做，我將不勝感激
