將Infopath .XML表單導入R中的數據框
[英]Import Infopath .XML forms into data frame in R
問題描述
在R中導入Infopath .XML表單並轉換為數據幀的最佳方法是什么？ 如果我在Excel中打開Infopath .XML文件，則數據框的行和列會正確顯示。
這是我在R中使用XML包嘗試的內容：
- 我使用xmlParse（）來解析XML文件
- 我使用xmlToDataFrame（）嘗試將解析后的XML文件轉換為數據框
但是，在第2步中，我收到以下錯誤：
Error in `[<-.data.frame`(`*tmp*`, i, names(nodes[[i]]), value = c("touch your head13011000", :
duplicate subscripts for columns
但是，當我在Excel中打開XML文件時，似乎沒有重復的列。 如何將此XML文件從Infopath轉換為R中的數據框？ 預期的列應該是（因為它們出現在Excel中）：
TCID, DateCoded, tcAge, T1_B3, T1_B2, T1_B1, T1_B0, T1_A3, T1_A2, T1_A1, T1_A0, T1_DelayTotal, T2_A3, T2_A2, T2_A1, T2_A, T2_B3, T2_B2, T2_B1, T2_B0, T2_DelayTotal, Coder, notes_t1, note_t2, bachildpres30, baparpres30, bapassptgo, bapassptnogo, bamissgame, P1_B3, P1_B2, P1_B1, P1_B0, P1_A3, P1_A2, P1_A1, P1_A0, P1_DelayTotal, P1_action, P1_go-nogo, P1_score, P1_delay, P1_trial, P1_Ecommand, P1_imitation, P1_restraint, P1_ruleswitch, P1_trials, P1_gotrials, P1_nogotrials, T1_gotrials, T1_nogotrials, T1_trials, T2_gotrials, T2_nogotrials, T2_trials, P1_notplay, T1_trial, T1_go-nogo, T1_score, T1_delay, T1_action, T2_trial, T2_go-nogo, T2_score, T2_delay, T2_action
對於在XML文件中多次出現的變量，我希望它們以長格式存在於數據框中（即，同一變量的多行）。 我對XML文件沒有太多經驗，所以非常感謝您的幫助。
下面是我使用xmlParse時解析的XML文件在R中的樣子：

根據我的經驗，只有當XML已經以非常一致的方式構建時， xmlToDataFrame才有效。 您正在使用的數據以多種不同方式構建：
# Assuming you've already read your data into a character vector called `xml_file
xml_file <- xmlParse(xml_file)
xml_file <- xmlToList(xml_file)
stack(sapply(xml_file, length))

因此，大多數節點都包含單個值。 有些是空的。 “SPSS”節點包含22個值，所有值都具有不同的名稱，“group2”，“group4”和“group6”都包含12個節點，每個節點包含多個值，但其值在節點之間相似。 當我查看Excel在導入文件時所執行的操作時，它將12個節點的組件堆疊在一起，然后將所有22個“SPSS”組件與所有單值節點串起來並重復該字符串通過堆疊12節點組件創建的行數，然后將這兩個塊綁定在一起。
為此，將長字符串與12節點塊分開：
xml_file_singles <- xml_file[sapply(xml_file, length) != 12]
xml_file_singles[sapply(xml_file_singles, length) == 0] <- NA
xml_file_singles <- unlist(xml_file_singles)
xml_file_multiples <- xml_file[sapply(xml_file, length) == 12]
現在取12節點塊並將每個塊轉換為數據幀：
xml_file_multiples <- lapply(1:length(xml_file_multiples), function(i) {
x <- lapply(xml_file_multiples[[i]], function(y) {
data.frame(as.list(unlist(y)), stringsAsFactors = FALSE)})
x <- do.call("rbind", x)
cbind("group" = names(xml_file_multiples)[i], x)
})
現在使用plyr包的rbind.fill函數將所有新數據幀放在一起：
require(plyr)
xml_file_multiples <- do.call("rbind.fill", xml_file_multiples)
現在cbind您的長字符串cbind綁定到綁定的數據幀：
xml_final <- cbind(as.list(xml_file_singles), xml_file_multiples,
stringsAsFactors = FALSE)
這種方法與Excel一樣，引入了大量的NA，因為不同12節點塊的列名略有不同。 如果你在調用rbind.fill之前這樣rbind.fill ：
xml_file_multiples <- lapply(1:length(xml_file_multiples), function(i) {
x <- lapply(xml_file_multiples[[i]], function(y) {
