Nim is not ready, even Python is missing several key R statistics packages.
I do try to implement what people find useful in Arraymancer, for example I
implemented randomized SVD and [randomized
PCA](https://github.com/mratsim/Arraymancer/pull/384)
With the results here:
To add to the very good answers so far, I'd mention that there is an issue
which tracks scientific libraries here:
[https://github.com/nim-lang/needed-libraries/issues/77](https://github.com/nim-lang/needed-libraries/issues/77)
And to answer your explicit question whether Nim is _suitable_ for
It's a wiki, we can edit it.
And it's better if people from the domain actually add the packages they find
useful like:
* data science / statistics: missing ggplotnim and nim-plotly
* bio: missing nim-hts
Though I strongly disagree with putting nimbus and blockchain in Finance.

I'm a bit perplexed that several people are saying this should be OK. Why
should a type's field be visible outside a module if the type itself is not
visible
Not really a solution to the problem but this could be an opportunity for you
to learn the underlying workings of the statistical algorithms you use by
creating a toy stats project in Nim. And you get an opportunity to learn Nim as
well ;-) All assuming you have the time, interest and energy of

I think such a list is not that bad for newcomers to get an overview what is
available.
But no nimble packages should be left out -- if you do not like gtk you can not
simple ignore all gtk related GUIs, and if you hate RTrees, or do not know
Well, I'm not sure what fixed it, but I was able to finally install Nim. I
updated a large amount of items on my computer and then was able to reinstall
Zim. Here is the subset of items that I updated that might of fixed my problem:

I would like to download an image file from the server and save it on my PC by
nim language.
At first, I wrote the following code:.

var client = newHttpClient()

> I find it complementary from nimble.directory
IMO, If nimble.directory was showing/grouping projects by using tags in
packages.json, curated list would be much less needed.
AFAIK, `Stream` is usually when you're dealing with bytes; whether opening
binary files, or reading/writing network bytes stream, or reading/writing bytes
to file etc.
Especially for writing bytes, just like in the example.
Hi Folks,
I have been exploring Nim since last night (completely noob), and wanted to get
a better feeling of code sharing between front and back, so I thought that
hacking this very forum would be a great start ! Unfortunately it doesn't seems
to compile with the 1.0 toolkit (either
If something does not compile, make a Bug on that project. IMHO.
If I understand you correctly, here you go:
import macros
type
Foo = enum
foo = "Foo"
bar = "Bar"
more = "More"
macro enumFields(n: typed): untyped =
let impl = getType(n)
expectKind impl[1], nnkEnumTy
result =
Very interesting, very interesting. Thanks.
@zio_tom78, I also thought about the lack of an REPL. Once Nim has it, this
should certainly make it all better.
I don't know much about Statistics, but this project might help you. Nim4Colab
is a IPython extension to use Nim language on Google Colaboratory.

Is there a command for that?
I've been looking for in the library but still haven't spotted anything.
Awesome! Thanks a lot!
@Vindaar \-- your implementation of `enumFields` is exactly what I was looking
for. Thank you very much and it's also a nice example of computing on the
language itself with macros.
May I ask what the main features are you'd require the ecosystem to provide for
you to consider Nim?
I'm asking since everyone's use cases are different and in my opinion it's
important to know what people actually want and need.
For instance for
> we just Nim someone to write the package
Assuming you meant "need" this is the best ever either slip of the
tongue/keyboard and/or entry auto-correct. "Nim".."need"..all the same. ;-)
Thank you. I appreciate your replies. And maybe I should have been more
explicit in my choice of words, even though I implied both Nim and its
ecosystem: maybe I should've written "Are Nim and its ecosystem at the moment
suitable for statistics?"
@Lecale, what do you mean by "Somn usor"?
Yes. I'm glad and thankful that you ask, and the importance of it is true. I'm
thinking quickly from the top of my head things like
* probability functions (Poisson, Binomial, Multinomial, etc.);
* a convenient function to nicely display a statistical summary of data
(possibly with argument
Somn usor means sleep well :) it is just a phrase I have in my head
A couple of weeks ago, I suggested the use of Nim in parallel with other
languages for teaching Software Engineering and Data Structures. I decided to
write a book about macros in Nim to help the students. However, in response to
requests from students, I asked their teachers to add

Thank you for an answer. Can't writeFile write binaries? When writeFile writes,
how does it break the image file?
The answer is simply: writeFile sure can write those and it shouldn't break it.
I do essentially the same here, the only difference is where the image comes
from:
Note that the writing of binary files was broken for 1.0.0 on Windows and 1.0.2
contains the fix.
