Warning messages:
1: C:\Documents and Settings\...\AA.sav: File-indicated character representation code (1252) looks like a Windows codepage in: read.spss(file.choose(), use.value.labels = F, to.data.frame = TRUE)

What happened?

建议不要直接读SPSS数据，即使foreign包中有read.spss()函数。
把数据转换为任何软件都可以读的通用格式，比如ASCII格式（*.txt，*.csv等），这样处理起来会方便很多。商业软件不开源，贸然去直接读指不定就出什么问题。

Just wield guess.
Maybe cos' your variable name contains Chinese characters.

haven't try .txt.
but i don't think .csv will suit my situation. cos my dataset is too large to fit in a excel datasheet.
my variable names are all english... are there any characters not allowed in variable names such as "_" or "$"? I'm not sure if it has those symbols included...

MS Office真是毒害人啊……在Windows系统上，若安装了Excel，则*.csv文件默认会用Excel打开，这样使人误以为csv就是Excel文件，其实它和Excel毫无关系，就是一个ASCII文件，数据用逗号分隔而已。
大数据只要内存能承受就能读进来。read.csv()

i see...
thanks a lot!

经验之谈，值得重视。
