各位大虾：
本人最近学习R软件，碰到一个问题，请帮忙看看：
1、想将SAS数据集读到R中，但提示：
> read.table(file.choose())
错误于read.table(file.choose()) : 空白的文件开头
此外: 警告信息：
1: In read.table(file.choose()) : line 1 appears to contain embedded nulls
2: In read.table(file.choose()) : line 2 appears to contain embedded nulls
3: In read.table(file.choose()) : line 3 appears to contain embedded nulls
4: In read.table(file.choose()) : line 4 appears to contain embedded nulls
5: In read.table(file.choose()) : line 5 appears to contain embedded nulls




谢谢！
