R中的Osmar包“文件错误(con，“r"):无法打开连接" [英] Osmar package in R "Error in file(con, "r") : cannot open the connection"

问题描述

我正在尝试在我的 Windows 10 R 3.4.2 上运行 osmar 包，并且已经正确安装了 osmosis.但是，当我尝试运行代码时:

I am trying to run the osmar package on my windows 10, R 3.4.2, and have correctly installed osmosis. However when I try to run the code:

>library("osmar")
>
>src <- osmsource_osmosis(file = "c:/users/ben_c/Documents/FYP/FYP_NL_Map/muenchen.osm", osmosis = "osmosis")
>
>
>nl_bbox <- center_bbox(11.575278, 48.137222, 3000, 3000)
>
>nl <- get_osm(nl_bbox, src)
>
>plot(nl)

我收到警告，在渗透运行后:

I get the warning, after osmosis has run:

>Error in file(con, "r") : cannot open the connection
>In addition: Warning message:
>In file(con, "r") :
>  cannot open file 
>'C:\Users\ben_c\AppData\Local\Temp\Rtmp8YYPkZ\file1b182fca7802': No such file or directory

我在运行演示时也遇到同样的错误:

I also get the same error when I run the demo:

>demo("navigator")

我对 R 比较陌生，所以非常感谢您的帮助.

I am relatively new to R so would really appreciate any help.

推荐答案

我有非常类似的错误.我可以通过以管理员身份运行 R(在我的例子中是 RStudio)来解决这个问题.

I had very similar error. I could solve the problem by running R (in my case RStudio) as administrator.

我认为问题在于无法创建临时文件.

I think the problem is that a temp file can't be created.
