在包含引號的sas中導入文件

Question

我想知道如何導入包含引號（「」）的SAS數據文件。

例如，文件中包含兩個變量：

"gray or green", "blond" 
"ble", "red" 
"brown", "rou" 
"gray or green", "blond" 
"blue", "brown" 
"brown", "black" 
"gray or green", "black" 

我嘗試下面的代碼：

data color ; 
    infile 'file path' DLM = " , " ; 
    input v1 $ v2 $ ; 
    v1 label = "eyes colour" v2 = "hair colour"; 
run; 

proc print data = color; 
run; 

Answer 1

格式爲CSV，你可以使用DSD選項來讀取文件。

DSD指定當數據值用引號引起來時，該值內的分隔符被視爲字符數據。當您使用LIST輸入並將默認分隔符設置爲逗號時，DSD選項將更改SAS如何處理分隔符。當您指定DSD時，SAS會將​​兩個連續的分隔符視爲缺失值並從字符值中刪除引號。

data want; 
infile cards DSD; 
informat var1 var2 $20.; 
input var1 $ var2 $; 
cards; 
"gray or green", "blond" 
"ble", "red" 
"brown", "rou" 
"gray or green", "blond" 
"blue", "brown" 
"brown", "black" 
"gray or green", "black" 
; 
run;
