1. 問題描述一個(gè)txt文件，使用R中的data.table包中的fread函數(shù)讀取時(shí)，報(bào)錯(cuò)： > dat = fread("test.txt")
Error in fread("test.txt") :
File is encoded in UTF-16, this encoding is not supported by fread(). Please recode the file to UTF-8.
使用read.table > dat = read.table("test.txt")
Error in type.convert.default(data[[i]], as.is = as.is[i], dec = dec, :
'<ff><fe><63>'多字節(jié)字符串有錯(cuò)
此外: Warning messages:
1: In read.table("test.txt") : line 1 appears to contain embedded nulls
2: In read.table("test.txt") : line 2 appears to contain embedded nulls
3: In read.table("test.txt") : line 3 appears to contain embedded nulls
4: In read.table("test.txt") : line 4 appears to contain embedded nulls
5: In read.table("test.txt") : line 5 appears to contain embedded nulls
6: In scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
embedded nul(s) found in input
2. 問題解決用notepad++查看了一下，編碼形式：「UCS-2」  所以，在read.table中，設(shè)定編碼形式：fileEncoding="UCS-2LE"
因此，修改后的代碼為： > dat = read.table("test.txt",fileEncoding = "UCS-2",header = T)
> head(dat)

「搞定！」。 3. 解決思路總結(jié)查看文件的編碼形式，用notepad++查看，然后定義編碼的類型，使用read.table讀取時(shí)，定義一下fileEncoding即可。以前我以為data.table包中的fread是萬(wàn)能的，沒想到它給出報(bào)錯(cuò)不支持UTF-16，最后還是用基礎(chǔ)包中的read.table解決了問題。 真香！
