在Mac上的R的stata文件中读取时，nchar()错误 [英] Error in nchar() when reading in stata file in R on Mac

问题描述

我正在学习R，只是试图读取stata数据文件，但出现以下错误:

I'm learning R and am simply trying to read in a stata data file but am getting the error below:

X<-Stata.file(Stata_File)

X <- Stata.file(Stata_File)

nchar(varlabs)中的错误:无效的多字节字符串253

此处的多个Mac用户在程序中遇到此错误，但在PC上运行正常.谷歌搜索此错误似乎表明它与R软件包有关，但我找不到解决方案.有任何想法吗?谢谢您的帮助！

Multiple Mac users here are encountering this error with the program but it works fine on a PC. A google search of this error seems to say it has something to do with the R package but I can't find a solution. Any ideas? Thanks for your help!!

直到错误点的R代码如下:

The R code up to the error point is below:

Root   <- "/Users/Desktop/R_Training"
PathIn <- paste(Root,"Data/Example_0",sep="/")

# The 2007 Dominican Republic household member file (96 MB) 
Stata_File <- "drpr51fl.dta"

# Load the memisc package:
library(memisc)

# Set the working directory:
setwd(PathIn)

# (1) Determine which variables we want:
# The Stata.file function (from memisc) reads the "header" 
#  of our Stata file so you can see what it contains
#  and choose the variables you want.
X <- Stata.file(Stata_File)

**Error in nchar(varlabs) : invalid multibyte string 253**

推荐答案

似乎文件中字符串的编码不是程序认为的那样. 我猜该文件是在PC上生成的?它包含非ACII列名或数据字符串吗?

It seems like the encoding of strings in the file isn't what the program thinks it is... I guess the file was generated on a PC? Does it contain non-ACII column names or data strings?

由于您似乎具有UTF-8编码，并且(美国/西欧)PC:通常具有latin-1，所以可能是问题所在.我希望在Linux上也遇到同样的问题(也是UTF-8).

Since you seem to have UTF-8 encoding, and (US/western europe) PC:s typically have latin-1, that could be the problem. I'd expect the same problem on Linux then (also UTF-8).

可能的解决方法: Stata.file方法是否具有编码"选项?然后，您可以尝试使用"latin1"并希望获得最好的结果.

Possible work-arounds: Does the Stata.file method have an "encoding" option? Then you might try 'latin1' and hope for the best...

另一种可能性是使用--encoding = latin1选项启动R.

Another possibility is to start R with the --encoding=latin1 option.
