我正在尝试修改数据帧，并努力将我的操作组合到一个for循环中。我想根据一个特定的列对数据帧进行子集处理，将不同的行附加到每个子集，然后将修改后的子集再次组合到一个单个数据帧中。让我们以虹膜数据为例：
#Create data frame subsets based on Species column
iris_subs <- split(iris, iris$Species)
#create an empty data frame with the same columns as in iris and one empty row
emptydf <- iris[FALSE,]
emptydf[nrow(emptydf)+1,] <- NA
#create a data frame with sums for each species
iris %>% group_by(Species) %>% summarise_all(sum) -> iris_sums
iris_sums <- iris_sums[,-c(1)] #delete column with species names
#Combine data frames into one data frame with original data, sum for this species and an empty row for each subset
iris_setosa <- bind_rows(iris_subs[1], iris_sums[1,], emptydf)
iris_versicolor <- bind_rows(iris_subs[2], iris_sums[2,], emptydf)
iris_virginica <- bind_rows(iris_subs[3], iris_sums[3,], emptydf)
new_iris <- bind_rows(iris_setosa, iris_versicolor, iris_virginica)
此代码完成了工作。但是，我要以这种方式处理数百个数据帧，并且每个数据帧的不同种类的数量各不相同。如何在for循环中自动化最后一部分？
我想要这样的东西
#empty data frame to store output
new_iris <- iris[FALSE,]
for (i in iris_subs) {
new_iris[i] <- bind_rows(iris_subs[i], iris_sums[i,], emptydf)
new_iris <- merge(new_iris[i])
}
Error in iris_subs[i] : invalid subscript type 'list'
除了错误，这可能太简单了……我是R初学者，已经在网上搜索了几天，但找不到任何答案。有人对如何实现这一目标有建议吗？谢谢您的提示！
答案 0 :(得分：2)
我们可以创建一个函数，并对所有数据框重复该函数。这是您尝试做的事情的简短版本
library(dplyr)
repeat_process <- function(df) {
iris_sums <- df %>% group_by(Species) %>% summarise_all(sum) %>% select(-Species)
df %>% bind_rows(iris_sums, emptydf[rep(1:nrow(emptydf), n_distinct(df$Species)), ])
}
现在让我们假设您有一个数据帧列表
list_df <- list(iris, iris)
您可以将此功能应用于列表中的每个数据框
lapply(list_df, repeat_process)
答案 1 :(得分：1)
您可以定义一个函数，该函数将合计data.frame的所有数字列，并将其他列保留为NA，并将其附加到原始数据框：

然后我们使用purrr映射每个子集：
numericCols = sapply(iris,is.numeric)
func = function(df,numCols){
iris_sums <- colSums(df[,numCols])
result <- rep(NA,ncol(df))
names(result) <- colnames(df)
result[names(iris_sums)] <- iris_sums
rbind(df,result,rep(NA,ncol(df)))
}
