データは次のとおりです。例1:完了

complete <- c("A", "B", "C","J", "C1", "L", "J2", "D", "M", "N")
lst1 <- c(NA, NA, NA, "A", "N", NA,"A", "C", "D", NA )
lst2 <- c(NA, NA, NA,"A", "L", NA, "C1", "J2", "J2", "B")
datf <- data.frame (complete, lst1, lst2, stringsAsFactors = FALSE)

例2:不完全で重複している

complete <- c("A", "B", "C","J", "C1", "L", "C", "D", "M", "N")
lst1 <- c(NA, NA, NA, "A", "N", NA,"A", "C", "D1", NA )
lst2 <- c(NA, NA, NA,"A", "L", NA, "C1", "J2", "J2", "B2")
datf2 <- data.frame (complete, lst1, lst2, stringsAsFactors = FALSE)

私はチェックしたい:(1)lst1とlst2のメンバーが少なくとも一度は完全に存在するかどうか。存在しない場合、停止メッセージはこれが「?」であることを示します。lst1またはlst2(正しいものは何でも)に存在しますが、完全ではありません。私の裁判:例えば1

if (datf$lst1 %in%  datf$complete | datf$lst2 %in%  datf$complete) {
     stop ("the subject in lst1 or lst2 must be complete list ")} else {
     cat("I am fine")
     }

I am fineWarning message:
In if (datf$lst1 %in% datf$complete | datf$lst2 %in% datf$complete) { :
  the condition has length > 1 and only the first element will be used

このエラーメッセージが表示されるのはなぜですか。また、どのように抑制できますか?

  Example 2:
    if (datf2$lst1 %in%  datf2$complete | datf2$lst2 %in%  datf2$complete) {
         stop ("the subject in lst1 or lst2 must be complete list ")} else {
         cat("I am fine")
         }
   Although there is potential errors the error message is same:
      I am fineWarning message:
    In if (datf2$lst1 %in% datf2$complete | datf2$lst2 %in% datf2$complete) { :
      the condition has length > 1 and only the first element will be used

エラーメッセージの一部として一致しない名前を提供する方法もあります。

(2)コンプリートのメンバーが重複している場合。

編集:

Expected answer:
Example1 <-  all members of lst1 and lst2 are also member of complete 

expacted message here is "I am fine"

Example2 <-
B2, J2, is member of lst2 but not complete, D1 is member of lst1 but not complete. 
complete have two C, so C is duplicated. 
The function will stop and print a message 

"B2 and J2 are member of lst1, but not in complete 
 D1  is member of lst2, but not in complete,
 check completeness" 
"C is duplicated in complete"

> datf$lst1 %in% datf$complete | datf$lst2 %in% datf$complete
 [1] FALSE FALSE FALSE  TRUE  TRUE FALSE  TRUE  TRUE  TRUE  TRUE

ifの引数から?'if'、NAではない長さ1の論理ベクトルです。

> na.omit(datf2$lst1)[!na.omit(datf2$lst1)%in%datf2$complete]
[1] "D1"
> na.omit(datf2$lst2)[!na.omit(datf2$lst2)%in%datf2$complete]
[1] "J2" "J2" "B2"

> datf2$complete[duplicated(datf2$complete)]
[1] "C"

上記は、提案したことを実行する関数を作成するのに役立ちます。
