I have this dataframe (57 rows, 9 cols) called "newData" and I'm trying to replace the NA values with the interpolated approximations and plot the graph. I've tried using functions such as na.approx and interp1 but I haven't managed to do it. Any solutions on how I can tackle this?

QUESTION
I'm working on a dataset with monthly air pollution data for a city in china. This is what it looks like.(all numericals are of class 'integer')
...ANSWER
Answered 2021-Jun-11 at 14:59This creates a zoo object, z
, and from that a ts object tt
whose columns are the individual series so z$SO2
or z[, "SO2"]
is an individual zoo series and tt[, "SO2"]
is an individual ts series. Generally it's a better idea to keep the series together and not create a bunch of variables in your workspace but if you want to do it anyways then the for
statement at the end will create a ts variable for each column.
QUESTION
I have a server application that has two deployments, one for the staging environment and another for the production environment. I have two individual scripts that are responsible for starting the processes. I would like to merge start_production.sh
and start_staging.sh
into start.sh
by reading the environment file.
start_production.sh
ANSWER
Answered 2021-Jun-06 at 14:03You could source
the .env
file. As the format KEY=value
is compatible with how bash does its environment variables. So in your case, start.sh
would be
QUESTION
So I did a lot of digging around the internet, and I have been unable to come up with the answer to my problem. My goal is that I want to print any errors that are logged to the console into a database. However, I have gone far enough into my project that it would be a pain to go back into my try...catch...
blocks and edit them with an error extender, or to just create my own function in the catch area.
I wanted to know: is there a specific way to create an error interception in NodeJS? I mean, I assume that whenever an error is logged to the console, the code fires some sort of event, and I guess I am looking for something like:
process.on(error, async (e) => { // my code here })
Is that at all possible? Is there a module that will allow me to do this? For context, I am running the latest version of Node/NPM on a headless Ubuntu 18.04 server, and am using pm2
to control my program processes.

QUESTION
I am writing an ansible playbook to perform various pm2 functions.
I have searched a bit and cannot find an example of someone setting up pm2-logrotate.
I believe I am close but I'm not sure my shell commands are working. When I ssh into the child node and run sudo pm2 ls
it says In-memory PM2 is out-of-date, do: $ pm2 update
even though I am running that command from my playbook. What am I missing here?

Answered 2021-May-24 at 22:03I was mixing up the users on my server. I fixed this by specifying to run as ubuntu for the update command.
QUESTION
I'm new to NGINX. I am trying to run my Node server with sudo pm2 start server.js
but I keep on getting MODULE_NOT_FOUND requireStack error. Everything's fine when I run it to a local machine but when I run on nginx, this keeps happening. I can't connect to my backend. Please, help.
I'm not sure if this will help, but when I also run node server.js
, I also get this error.

QUESTION
I got error when creating deployment. This is my Dockerfile that i have run and test it on local, i also push it to DockerHub
...ANSWER
Answered 2021-May-21 at 06:45You are trying to launch a container built for x86 (or x86_64, same difference) on an ARM machine. This does not work. Containers for ARM must be built specifically for ARM and contain ARM executables. While major projects are slowly adding ARM support to their builds, most random images you find on Docker Hub or whatever will not work on ARM.
QUESTION
I am using the MEAN Stack and I could run my frontend already. After ng build
I moved all the content in the dist
folder to var/www/html
and could access my website. I'm using Apache and my frontend is now available online. The problem is now my backend. I am using Node.js but I have no clue how I can make it "online" for everyone. With npm start server.js
or pm2 start server.js
I can make my Node.js server run and everything is working fine, but it's only working for me. When my friend accessed my website, the backend is not running (only frontend).
So my question is, how can I make my node.js server public? Is there a way to run node.js in Apache also?
Actually I made a apache proxy and even with nginx but seems not to work yet...
I followed this step from here: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-14-04
and also from here: https://medium.com/@pierangelo1982/using-nodejs-app-with-apache-374b37c6140d
EDIT:
I am able to server my backend with nginx but I have to stop my Apache server but my apache server is serving the angular frontend...
What should I do?
EDIT2:
Thanks of the help from Gouveia, I am able to serve front and backend with NGINX
...ANSWER
Answered 2021-May-16 at 10:21When you run npm start server.js
, you are running a server on its own.
If you want all requests to go through Apache, then you can use simple reverse proxy to connect from Apache to your nodejs backend (assuming your node js server runs on port 8080):
