（1）今天在读取数据的时候，出现一个报错：
f_anno <- read.table("anno_new.txt",
sep = "\t",
header = T,
check.names = F,
fill = T,
na.strings = "")
Warning message:
In scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :
EOF within quoted string
（2）解决方法：
方法一：调用Sys.setlocale("LC_ALL", "English")
方法二：禁用qutoe，即设置quote = ""，你把语句改为sms_raw <- read.csv("E:/R/mlrdatasets/sms_spam.csv", stringsAsFactors = FALSE,quote = "")
方法三：编码问题，把读取编码设置为fileEncoding = "Latin1"
我选用了方法二，目前已经解决。
