I am working on a React app where i want to display charts. I tried to use react-chartjs-2 but i can't find a way to make it work. when i try to use Pie component, I get the error: Error: "arc" is not a registered element.
I did a very simple react app:
- npx create-react-app my-app
- npm install --save react-chartjs-2 chart.js
Here is my package.json:

ANSWER
Answered 2021-Oct-15 at 21:11Found the problem.
I was installing pandas_profiling
, and this package updated pyyaml
to version 6.0 which is not compatible with the current way Google Colab imports packages.
So just reverting back to pyyaml
version 5.4.1 solved the problem.
For more information check versions of pyyaml

QUESTION
I'm trying to use packages that require Rcpp

ANSWER
Answered 2022-Feb-10 at 21:07Currently (2022-02-05), CRAN builds R binaries for Apple silicon using Apple clang
(from Command Line Tools for Xcode 12.4) and an experimental build of gfortran
.
If you obtain R from CRAN (i.e., here), then you need to replicate CRAN's compiler setup on your system before building R packages that contain C/C++/Fortran code from their sources (and before using Rcpp
, etc.). This requirement ensures that your package builds are compatible with R itself.
A further complication is the fact that Apple clang
doesn't support OpenMP, so you need to do even more work to compile programs that make use of multithreading. You could circumvent the issue by building R itself and all R packages from sources with LLVM clang
, which does support OpenMP, but this approach is onerous and "for experts only". There is another approach that has been tested by a few people, including Simon Urbanek, the maintainer of R for macOS. It is experimental and also "for experts only", but seems to work on my machine and is simpler than trying to build R yourself.
Warning: These instructions come with no warranty and could break at any time. They assume some level of familiarity with C/C++/Fortran program compilation, Makefile syntax, and Unix shells. As usual, sudo
at your own risk.
I will try to address compilers and OpenMP support at the same time. I am going to assume that you are starting from nothing. Feel free to skip steps you've already taken, though you might find a fresh start helpful.
I've tested these instructions on a machine running Big Sur, and at least one person has tested them on a machine running Monterey. I would be glad to hear from others.
Download an R binary from CRAN here and install. Be sure to select the binary built for Apple silicon.

QUESTION
I have a large dataset (~5 Mio rows) with results from a Machine Learning training. Now I want to check to see if the results hit the "target range" or not. Lets say this range contains all values between -0.25
and +0.25
. If it's inside this range, it's a Hit
, if it's below Low
and on the other side High
.
I now would create this three columns Hit, Low, High and calculate for each row which condition applies and put a 1
into this col, the other two would become 0
. After that I would group the values and sum them up. But I suspect there must be a better and faster way, such as calculate it directly while grouping. I'm happy for any idea.

QUESTION
I was wondering if anyone knows a way to combine a table and ggplot legend so that the legend appears as a column in the table as shown in the image. Sorry if this has been asked before but I haven't been able to find a way to do this.
Edit: attached is code to produce the output below (minus the legend/table combination, which I am trying to produce, as I stitched that together in Powerpoint)
...ANSWER
Answered 2021-Dec-31 at 13:24This is an interesting problem. The short answer: Yes, it's possible. But I don't see a way around hard coding the position of table and legend, which is ugly.
The suggestion below requires hard coding in three places. I am using {ggpubr} for the table, and {cowplot} for the stitching.
Another problem arises from the legend key spacing for vertical legends. This is still a rather unresolved issue for other keys than polygons, to my knowledge. The associated GitHub issue is closed The legend spacing is not a problem any more. Ask teunbrand, and he knows the answer.
Some other relevant comments in the code.
QUESTION
I am plotting some multivariate data where I have 3 discrete variables and one continuous. I want the size of each point to represent the magnitude of change rather than the actual numeric value. I figured that I can achieve that by using absolute values. With that in mind I would like to have negative values colored blue, positive red and zero with white. Than to make a plot where the legend would look like this:
I came up with dummy dataset which has the same structure as my dataset, to get a reproducible example:

Install dataset
You can use dataset like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
