我想使用rpy2将R和Python结合起来。更具体地说，我正在尝试使用其他人编写的使用rpy2的代码。 我认为使用rpy2的代码是：
import rpy2.robjects as robjects
integrated_result = 0
r1=robjects.r
r1.source("integrate_result.R")
integrated_result = r1.integrate_result(filename_list = mask)
“integrate_result.R” 以 “library(BayesFactor)” 开始，其中包含一个名为 “integrate_result”的函数。当我尝试运行它时，会出现以下错误：
R[write to console]: Error in library(BayesFactor) : there is no package called 'BayesFactor'
Error in atexit._run_exitfuncs:
Traceback (most recent call last):
File "C:\Users\XYZ\AppData\Local\Programs\Python\Python37\lib\contextlib.py", line 130, in __exit__
self.gen.throw(type, value, traceback)

raise embedded.RRuntimeError(_rinterface._geterrmessage())
rpy2.rinterface_lib.embedded.RRuntimeError: Error in library(BayesFactor) : there is no package called 'BayesFactor'
当我使用 R 本身时，该软件包已经被安装了。我也尝试过使用 rpy2 安装该软件包，方法如下：
>>> import rpy2.robjects.packages as r
>>> utils = r.importr("utils")
>>> package_name = "BayesFactor"
>>> utils.install_packages(package_name)

有人有什么想法吗？
utils.install_packages(package_name)的代码片段的结果是什么？ - desertnautpython -m rpy2.situation可能会帮助其他人回答你的问题 :) - krassowski
