黑客在 Haven::read_sav() 的文件路径中包含特殊字符

2024-01-11

There 似乎是一个问题 https://github.com/tidyverse/haven/issues/371当文件路径中包含任何类型的特殊字符（仅包括文件名）时，使用 Haven (1.1.1) 包。

假设这是一个真正的问题，我正在寻找某种巧妙的黑客/解决方案来解决它。

一个（不理想的）例子是让 R 将文件的副本放入更友好的路径中，并给它一个“更好”的文件名，然后使用 Haven 加载。例如：

setwd("c:/temp")
fn <- "randóóm.sav"
file.copy(paste0("./äglæpath/", fn), fn)
file.rename(fn, gsub("[^-\\./a-zA-Z0-9[:space:]]", "", fn))
# now apply read_sav() to the copy

我在用着：

R version 3.5.0 (2018-04-23)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows >= 8 x64 (build 9200)

不幸的是，我已经能够在 Windows 10 上使用标准版本重现该问题haven和devtools的版本haven。这似乎是避风港的已知错误。#371 https://github.com/tidyverse/haven/issues/371

Github 错误 #371

Read_*() 不适用于文件路径中的特殊字符 #371https://github.com/tidyverse/haven/issues/371 https://github.com/tidyverse/haven/issues/371

问题代码在DfReader.cpp https://github.com/tidyverse/haven/blob/746eb3e8c456136c8ff047478741b7d1625ec039/src/DfReader.cpp#L594df.parse_dta()594-612 https://github.com/tidyverse/haven/blob/746eb3e8c456136c8ff047478741b7d1625ec039/src/DfReader.cpp#L594 in haven/src/DFReader.cpp.

重现代码

require(haven)
require(stringi)

dtaURL  <- "https://github.com/tidyverse/haven/blob/master/inst/examples/iris.dta?raw=true"
bdatURL <- "https://github.com/tidyverse/haven/blob/master/inst/examples/iris.sas7bdat?raw=true"
savURL  <- "https://github.com/tidyverse/haven/blob/master/inst/examples/iris.sav?raw=true"

dtaFilename   <- "randóóm.dta"
bdatFilename <- "randóóm.bdata"
savFilename   <- "randóóm.sav"

dataFilepath      <- "äglæpath"

if (!dir.exists(dataFilepath)) {
  dir.create(file.path(dataFilepath), showWarnings = TRUE)
}

dtaDest = file.path(dataFilepath, dtaFilename)
bdatDest = file.path(dataFilepath, bdatFilename )
savDest = file.path(dataFilepath, savFilename )

download.file(dtaURL, destfile = dtaDest, method = "wget", mode = "wb")
download.file(bdatURL, destfile = bdatDest, method = "wget", mode = "wb")
download.file(savURL, destfile = savDest, method = "wget", mode = "wb")


# Stata
read_dta(dtaDest)

# SAS
read_sas(bdatDest)

# SPSS
read_sav(savDest)

控制台输出
