gsub for 循环创建重复的字符串
gsub for loop creates a repeated character string
问：

)), row.names = c(NA, -50L), class = c("tbl_df", "tbl", "data.frame"
))
我想做的是确定 test2$AU 中有一个来自 1 test2$Author.s. 的不同名称。所以我制作了这个脚本：
library(tidyverse)
library(stringr)
au <- strsplit(test2$AU, ";")
author_ids <- strsplit(test2$Author.s..ID, ";")
max_elements <- max(lengths(au), lengths(author_ids))
au <- lapply(au, function(x) c(x, rep(NA, max_elements - length(x))))
author_ids <- lapply(author_ids, function(x) c(x, rep(NA, max_elements - length(x))))
author_data <- data.frame(
AU = unlist(au, use.names = FALSE),
Author.s..ID = unlist(author_ids, use.names = FALSE)
)
author_data <- na.omit(author_data)
author_data$Author.s..ID <- gsub(" ","", author_data$Author.s..ID)
author_data <- unique(author_data)
mismatches <- author_data %>%
group_by(Author.s..ID) %>%
summarize(AU_count = n_distinct(AU))
mismatches <- mismatches %>%
filter(AU_count > 1)
if (nrow(mismatches) > 0) {
print(mismatches)
} else {
cat("No mismatches or variations found.")
}
然后我做一个 for 循环来替换所有不匹配的东西：
for (i in 1:nrow(mismatches)) {
q <- mismatches[i, 1]
rows <- author_data[which(author_data$Author.s..ID == as.character(q)), ]
for (y in 1:nrow(rows)) {
name_replaced <- rows$AU[2:y]
name_fixed <- rows$AU[1]
for (j in 1:nrow(test2)) {
for (k in 1:length(name_replaced)) {
if (grepl(name_replaced[k], test2$AU[j])) {
test2$AU[j] <- gsub(name_replaced[k], name_fixed, test2$AU[j])
} else {test2$AU[j] <- test2$AU[j]
}
}
}
}
}
我制作的 for 循环创建了一个奇怪的字符串子，它重复了字符，如果我尝试运行循环，我仍然不匹配并且输出仍然不正确。
author_data[which(author_data$Author.s..ID == "56979441000"),]
我哪里做错了？
谢谢！

如果你最终想做的是找到多次归因的 ID 和具有多个 ID 的作者，我建议你首先整理数据，每行有一个作者和作者 ID。然后，查找重复项就变得容易多了：
library(tidyverse)
# tidy up your data
test2 <- test2 |>
mutate(ManuscriptID = row_number(), # I assumed these are articles or manuscripts?
AU = map(AU, \(x) trimws(unlist(strsplit(x,";")))),
Author.s..ID = map(Author.s..ID, \(x) trimws(unlist(strsplit(x,";"))))) |>
unnest(c(AU, Author.s..ID))
# find Authors having multiple IDs
test2 |>
group_by(AU) |>
filter(n()>1) |>
arrange(Author.s..ID)
# deal with Authors having multiple IDs
# ... insert your own code here
# find IDs attributed multiple times
test2 |>
group_by(Author.s..ID) |>
filter(n()>1) |>
arrange(Author.s..ID)
# deal with IDs attributed multiple times
# ... insert your own code here
# restore the previous data structure
test2 |>
group_by(ManuscriptID) |>
summarise(across(everything(), ~ paste(.x, collapse="; ")))
在这两种情况下，我都由您决定如何更改重复的 ID。

你不需要在这里使用。我同意另一个答案，即您想将数据以长格式显示。我就是这样做的：gsub()
author_id <- data.frame(
AU = unlist(strsplit(test2$AU, ";")),
ID = trimws(unlist(strsplit(test2$Author.s..ID, ";"))),
grp = cumsum(sequence(lengths(strsplit(test2$AU, ";"))) == 1)
)
该列稍后将用于将数据放回宽格式。grp
您的问题似乎是将作者姓名的拼写略有不同，并替换为该名称的第一个实例。例如：
filter(author_id, ID == "57189010056")
# AU ID grp
# 1 MÂNICA S 57189010056 3
# 2 MÂNICA S 57189010056 23
# 3 MANICA S 57189010056 45
当您使用 时，您可以非常简单地做到这一点：tidyverse
# Replace the author names with the first instance
author_id <- author_id |>
group_by(ID) |>
mutate(AU = AU[1])
这解决了问题，例如，使用前面的示例：
filter(author_id, ID == "57189010056")
# AU ID grp
# <chr> <chr> <int>
# 1 MÂNICA S 57189010056 3
# 2 MÂNICA S 57189010056 23
# 3 MÂNICA S 57189010056 45
现在我们可以将数据放回宽格式：
# Put the data back in wide form
ids_wide <- author_id |>
split(~grp) |>
lapply(\(df) data.frame(
AU = paste(df$AU, collapse = ";"),
`Author.s..ID` = paste(df$ID, collapse = "; ")
)) |>
bind_rows()
输出：
head(ids_wide)[-2,] # Line 2 is long and wraps terminal
# AU Author.s..ID
# 1 MEISYARA D;GUSWENRIVO I;SINGHAM GV 57211806807; 57192983097; 36952129500

谢谢！这很简单，但它解决了所有问题。我需要回去学习基础知识..
