试图聚合R中的ReactionTypes

Question

outAct的样本

Activity      ReactionType      numberActivities

activator     activates         16
binding       binds             83
recombinase   binds             1
branching     branches          3
carboxylase   carboxylates      36
peptidase     cleaves           425
endopeptidase cleaves           368
nuclease      cleaves           53
glycosylase   cleaves           24
cyclase       converts          12
transhydrogenase converts       3
hist deacetylase deacetylates   8
deacetylase   deacetylates      16

我想计算所有相同的ReactionTypes并总结它们的numberActivities

reaction_types <-aggregate(numberActivities ~ ReactionType, unique(outAct), FUN=sum)

期望的输出

ReactionType    number

activates       16
binds           84
branches        3
carboxylates    36
cleaves         870
converts        15
deacetylates    24

问题是，我得到重复，即它们不算作一个唯一的反应类型，例如输出包含诸如

之类的行

deacetylates    8
deacetylates    16

整个输出文件中有更多这样的例子。 我哪里错了？

提前致谢。

Answer 1

library(dplyr)
outAct %>% group_by(ReactionType) %>% summarise(number = sum(numberActivities))
