我正在尝试从此website下载一个时间序列-这是我试图获取的最后一个项目。我正在使用 pdfetch ，因为它通常很快。只需输入该系列的代码即可完成工作。但是，这次我遇到了我无法解决的错误。在问题下方找到。
library(pdfetch)
pdfetch_ECB("ICP.M.U2.Y.XEFUN0.3.INX")
Error in xts(as.matrix(suppressWarnings(as.numeric(fr[, 2]))), dates, :
'order.by' cannot contain 'NA', 'NaN', or 'Inf'
有人能解决吗？
非常感谢！

这似乎是一个语言环境问题，最可能的原因是lubridate无法解析您的语言环境中downloaded csv document的不寻常的英语年-月格式。
我可以这样做来复制您的错误
Sys.setlocale("LC_ALL", "Italian_Italy.1252")
pdfetch_ECB("ICP.M.U2.Y.XEFUN0.3.INX")
#> Error in xts(as.matrix(suppressWarnings(as.numeric(fr[, 2]))), dates, :
#> 'order.by' cannot contain 'NA', 'NaN', or 'Inf'
并通过进行修复
Sys.setlocale("LC_ALL", "English_United Kingdom.1252")
pdfetch_ECB("ICP.M.U2.Y.XEFUN0.3.INX")
#> ICP.M.U2.Y.XEFUN0.3.INX
#> 1997-01-31 75.45
#> 1997-02-28 75.52
#> 1997-03-31 75.59
#> 1997-04-30 75.61
#> 1997-05-31 75.71
#> 1997-06-30 75.76
#> ...
所以这应该对您有用：
Sys.setlocale("LC_ALL", "English_United Kingdom.1252")
result <- pdfetch_ECB("ICP.M.U2.Y.XEFUN0.3.INX")
Sys.setlocale("LC_ALL", "Italian_Italy.1252")
