“导入为"在R中 [英] "import as" in R

问题描述

是否有一种方法可以导入R中具有其他名称的包，就像您在Python中使用import as时那样，例如import numpy as np?我最近开始使用package::function来避免Hmisc::summarize和plyr::summarize之间的冲突.

Is there a way to import a package with another name in R, the way you might with import as in Python, e.g. import numpy as np? I've been starting to use package::function lately to avoid conflicts between, say, Hmisc::summarize and plyr::summarize.

我希望能够分别编写h::summarize和p::summarize.在R中可以吗?

I'd like to be able to instead write h::summarize and p::summarize, respectively. Is this possible in R?

推荐答案

使用

Use the namespace package to generate another namespace aliased to the one you are interested in.

library(namespace)
registerNamespace('ggp', loadNamespace('ggplot2'))
data(iris)
ggp::ggplot(iris, ggp::aes(x = Petal.Length, y = Sepal.Length)) + ggp::geom_point()

请注意，这样做的缺点是使脚本的软件包版本控制/安装要求更加不透明.

Note this has the disadvantage of making the package versioning/installation requirements more opaque for scripts.
