关于R读取数据时出现的问题，请指教！谢谢

回复 第4楼 的 谢益辉：好的 。

第一台电脑我还以为是版本问题，卸载后，刚装的R,还是以下问题：

##########################################################

a_1=read.csv("shiyan.csv")

错误于make.names(col.names, unique = TRUE) : 多字节字符串1有错

此外: 警告信息：

In read.table(file = file, header = header, sep = sep, quote = quote, :

readTableHeader在读取'shiyan.csv'时遇到了不完全的最后一行

> count.fields("shiyan.csv")

第二台电脑也有问题：

错误于make.names(col.names, unique = TRUE) : 多字节字符串1有错

此外: 警告信息：

第三台电脑上原来没有问题，但现在又有问题了：

3.1：有问题

data1= read.csv("shiyan.csv")

错误于make.names(col.names, unique = TRUE) : 多字节字符串1有错

此外: 警告信息：

In read.table(file = file, header = header, sep = sep, quote = quote, :

3.2：没问题

数据"shiyan.csv"和"data.csv"是一致的，都是109*2列的数据
