不是错误，更多的是在构造data.frame时对基础类型系统转换(character类型和factor类型)的误解.

Not a bug, more a misunderstanding of the underlying type system conversions (the character type and the factor type) when constructing a data.frame.

您可以先从data <-read.csv("mydata.csv", encoding="UTF-8", stringsAsFactors=FALSE)开始，这将使您的汉字成为character类型，因此通过将它们打印出来，您应该会看到期望的文字.

You could start first with data <-read.csv("mydata.csv", encoding="UTF-8", stringsAsFactors=FALSE) which will make your Chinese characters to be of the character type and so by printing them out you should see waht you are expecting.

@nograpes:类似x=c('中華民族');x; y <- data.frame(x, stringsAsFactors=FALSE)，一切正常.

@nograpes: similarly x=c('中華民族');x; y <- data.frame(x, stringsAsFactors=FALSE) and everything should be ok.
