Question

很抱歉打扰你，可能是一个编码问题。花了几个小时没有得到解决方案我决定在这里发布。我试图使用来自Ubuntu 14.04的write.table，write.csv，write.csv2来写一个简单的表失败。我的数据因cronjob而变得混乱：

ID <- c("",30,26,20,30,40,5,10,4)
b <- c("",2233,12,2,22,13,23,23,100)
c <- c("","","","","","","","","")
d <- c("","","","","","","","","")
e <- c("","","","","","800","","","")
f <- c("","","","","","","","","")
g <- c("","","","","","","","EA","")
h <- c("","","","","","","","","")
df <- data.frame(ID,b,c,d,e,f,g,h)

  # change columns to chr
for(i in c(1,2:ncol(df))) {
 df[,i] <- as.character(df[,i])
}

str(df)

# data.frame':  9 obs. of  8 variables:
#  $ ID: chr  "" "30" "26" "20" ...
#  $ b : chr  "" "2233" "12" "2" ...
#  $ c : chr  "" "" "" "" ...
#  $ d : chr  "" "" "" "" ...
#  $ e : chr  "" "" "" "" ...
#  $ f : chr  "" "" "" "" ...
# $ g :  chr  "" "" "" "" ...
#  $ h : chr  "" "" "" "" ...


head(df,n=9)

    ID    b c d   e   f  g  h
# 1                       
# 2 30 2233               
# 3 26   12               
# 4 20    2               
# 5 30   22               
# 6 40   13      800       
# 7  5   23               
# 8 10   23              EA  
# 9  4  100

我尝试过在SO上找到的不同组合和建议，但没有任何效果。结果总是以某种方式取代而不是长期的。在当前示例中，只有一行。

我试过了：

write.table(df,"df.csv",row.names = FALSE, dec=".",sep=";")
write.table(df,"df.csv",row.names = FALSE,dec=".",sep=";", col.names = T)
write.table(df,"df.csv",row.names = FALSE,sep=";",fileEncoding = "UTF-8")
write.table(df,"df.csv",row.names = FALSE,fileEncoding = "UTF-8")

问题不在于R或Ubuntu它是记事本。具体来说，它预计会有"\r\n"换行符，而大多数其他文字阅读器会对"\n"感到满意，write.xxx是eol="\r\n"使用的默认换行符。

如果您添加参数write.table(df,"df.csv",row.names = FALSE, dec=".",sep=";",eol="\r\n")，那么您应该可以在记事本中打开并查看预期的换行符。

例如：

MediaPlayer mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mPlayer.setDataSource(context.getExternalFilesDir("krishna").getPath() + "/amalharinaam_finalcut_loud.mp3"));
mPlayer.prepareAsync();

如何使用带记事本可识别的换行符的R保存CSV文件？
