R:进入“内部"环境 [英] R: getting "inside" environments

问题描述

给出一个environment对象e:

> e
<environment: 0x10f0a6e98>
> class(e)
[1] "environment"

如何访问环境中的变量?

How do you access the variables inside the environment?

以防万一您感到好奇，我发现自己使用了这个environment对象.我没做，是用Bioconductor的包装做的.您也可以使用以下命令来做到这一点:

Just in case you're curious, I have found myself with this environment object. I didn't make it, a package in Bioconductor made it. You can make it, too, using these commands:

library('GEOquery')
eset <- getGEO("GSE4142")[[1]]
e <- assayData(eset)

推荐答案

ls(e)为您提供环境中对象的名称，而e$name_of_object为您提供指定的对象(或e[["a"]]或get("a",e)).

ls(e) gives you names of objects in the environment and e$name_of_object gives you specified object (or e[["a"]], or get("a",e)).
