QUESTION
I have a simple code to use the LHS design of the experiment, and it works fine.
...ANSWER
Answered 2022-Apr-01 at 23:30I found the answer for my post.
It seems it makes difference where to put mycode.py
file and using the pyinstaller
.
The file needs to be where your python is installed, in the scripts folder
. Then, we can use pyinstaller mycode.py
.
QUESTION
I'm following the vegan tutorial on procrustes analysis:
https://www.rdocumentation.org/packages/vegan/versions/2.4-2/topics/procrustes
...ANSWER
Answered 2022-Jan-27 at 03:09It's not exactly the same, but I think it's pretty close.
I brought the varespec
data into Python for this. Then tried to mimic the actions that the vegan
package (and your code) took. Along those lines, I stuck to the object names you used (for the most part).
There has to be an easier way to do this.

Let's say I have a vector x1
as a numpy array in the python environment. I want to transfert that vector to the R environment, do some computations using R specific functions and then get another vector x2
and then want to transfer x2

Looking for help on using rpy2 in python script with vscode from WSL. I can't get the import to work.
If i try to run the following code:
...ANSWER
Answered 2021-Nov-21 at 22:30There is no module or sub-package rpackages
in rpy2, so the error message when trying to import it is expected.
The error about a circular a partially initialized module is surprising. Do you happen to have a directory called rpy2
where you are running this from? Python would try to import that directory.
QUESTION
I have the following method that checks whether an R package is installed. This helps me avoid installing the package every time I run the code.
I want to add functionality so we can check if the R package is installed AND if it's the latest version. I've had a look at the rpy2 documentation though and I can't see a way to do this.
I was wondering if anyone had any ideas on how I can achieve this? Cheers
...ANSWER
Answered 2021-Nov-13 at 20:18You can use two other functions available in utils
to get versions of installed and available packages and compare the two to get an answer. The relevant R code is provided in https://stackoverflow.com/a/2563683, which can be translated to Python as below:

ANSWER
Answered 2021-Oct-04 at 12:29Your example is showing just R code without any python functions used.
Option 1 (easy, without jupyter and python)If you really do not need Jupyter and python, you can just create documents with R code cells and text in between using RMarkdon inside RStudio.
Option 2 (hard, with jupyter and python)- install R and python
- install Jupyter
- install rpy2 using
! pip install rpy2
inside a jupyter cell - Run R code within the notebook:
QUESTION
tl;dr Can I configure rpy2 so that it loads the conda installation instead of the system one?
My issue
When I run rpy2
it uses the system installation of R, but it introspects and loads libraries from my conda installation of R.
This has various side effects such as segfaults and so on...
Reproduction
I have an installation of R on a Ubuntu 18 server, that my sysadmin has installed. I want to use conda with python and rpy2 to make sure I can select versions somewhat freely.
Below, you can see I am in a conda environment called (rnvp)
, that rpy2
identifies the 4.0.5 conda installation of R, but that the rpy2.robjects
library loads the system R installation instead, which is 4.0.3.
When running the situation
script, I get the below

Answered 2021-Aug-26 at 12:02Recompile rpy2 locally, with a linker flag to explicate which R library to link to.
Inspired by the blog post https://thomas-cokelaer.info/blog/2012/01/installing-rpy2-with-different-r-version-already-installed/ I decided to recompile rpy2
from source, and supply the R path as an environment variable to the compilation.
