data.table中的fread在Ubuntu和Mac OSX中表现不同

我通常运行两个不同的R会话。一个是Ubuntu设置下的RStudio服务器，另一个是Mac上的本地会话。我一直在使用

data.table

的

fread

函数读取文件，我得到了意想不到的行为。在Mac上读取一系列文件时，我没有收到任何错误，但在Ubuntu服务器上运行相同的代码时，我会收到以下错误：

（A） fread中的错误（csv，verbose=F，colClasses=list（character=1:col.num））： 不允许使用负长度向量

（B） fread中的错误（temp[3]，verbose=T，colClasses=list（character=1:451））： 测试标题行格式后未正确定位。ch='，

这些文件系列有许多列（每个表超过500列），因此手动查找错误对我来说并不那么容易。还有其他人有这个问题吗？两个实例都在运行

data.table 1.9.3

以下是我的Ubuntu服务器会话信息：

以下是其中一个数据集的verbose=T消息：

data <- fread(temp[1],verbose=T)

Input contains no \n. Taking this to be a filename to open
File opened, filesize is 0.002 GB
File is opened and mapped ok
Detected eol as \r only (no \n afterwards). An old Mac 9 standard, discontinued in 2002 according to Wikipedia.
Using line 30 to detect sep (the last non blank line in the first 'autostart') ... sep=','
Found 453 columns
First row with 453 fields occurs on line 1 (either column names or first row of data)
All the fields on line 1 are character fields. Treating as the column names.
Count of eol after first data row: 2723
Subtracted 0 for last eol and any trailing empty lines, leaving 2723 data rows

data如何运行
data.table 1.9.3
？最新的稳定版本是
1.9.2
data。表1.9.3
Hi。请使用
verbose=TRUE
再次运行并粘贴完整输出。希望这能给我足够的线索来修复它。它在不指定
colClasses
的情况下工作吗？只添加了
verbose=T
的结果（我编辑了结果以符合堆栈溢出帖子的30000字符限制）。当我没有指定
colClassses
时，我的R会话将中止一些我试图引入的数据表。我的数据确实有带引号的字段，而且数据来自墨西哥，所以到处都是重音符号和波浪符号。我不确定这是否重要。如果我不指定“colClasses”，MacOSX和Ubuntu中的R会话都会中止。谢谢。请注意顶部附近的一行：
仅检测到eol（之后没有）。一个旧的Mac 9标准，据维基百科称，该标准于2002年停止使用。
该文件是否已有十多年历史？否则，在检测行尾时会出现问题。字段中是否嵌入了
\r
？你能把这个文件（看起来很小）发给
维护者（“data.table”）
？
