英文:
Importing .obo file with OntologyX package in R results in 'attempt to set an attribute on NULL' error
问题
使用ontologyX包导入.obo文件时出现问题。
我想使用R包ontologyX导入people.obo文件：
library(ontologyIndex)
hp <- get_OBO("people.obo")
我已经从这个本体创建了obo文件：
https://www.michaeldebellis.com/post/the-people_example-ontology
使用这个工具：
http://robot.obolibrary.org/convert
当我尝试导入时，我得到了以下结果：
> hp <- get_OBO("people.obo")
Error in names(object) <- nm : attempt to set an attribute on NULL
如果我尝试使用protege将owl转换为obo，或者使用Pizza本体，我也遇到了相同的问题：

都不起作用。
但是，当我尝试打开go-basic.obo文件时一切正常：

有什么帮助吗？
英文:
Problem with importing .obo file with onotolgyX package.
I want to import people.obo with R package ontologyX:
library(ontologyIndex)
hp <- get_OBO("people.obo")
I have created obo file from this ontology:
https://www.michaeldebellis.com/post/the-people_example-ontology
With this tool:
http://robot.obolibrary.org/convert
I get this result when I want to import it:
> hp <- get_OBO("people.obo")
Error in names(object) <- nm : attempt to set an attribute on NULL
I get the same problems if I convert owl to obo with protege or if I use Pizza ontology:
https://www.michaeldebellis.com/post/new-protege-pizza-tutorial
It doesn't work.
But everythnig works fine when I try to open go-basic.obo

"包的作者回答 
'name'属性未分配给obo文件中的术语 - 这应该是允许的 - 所以我已经更新了包（请参见版本2.11），以便如果名称不存在，则使用'id'（应该很快在CRAN上可用，并且可以在您提供的示例上工作）."
英文:
The answer from the author of the package
'name' properties were not assigned to terms in the obo file - which should be allowed - so I have updated the package (see version 2.11) so that it uses the 'id' if the name is absent (should be on CRAN shortly and work on the examples you provided).
