lazydata | Lazydata : Scalable data dependencies for Python projects

kandi X-RAY | lazydata Summary
lazydata is a minimalist library for including data dependencies into Python projects. Problem: Keeping all data files in git (e.g. via git-lfs) results in a bloated repository copy that takes ages to pull. Keeping code and data out of sync is a disaster waiting to happen. Solution: lazydata only stores references to data files in git, and syncs data files on-demand when they are needed. Why: The semantics of code and data are different - code needs to be versioned to merge it, and data just needs to be kept in sync. lazydata achieves exactly this in a minimal way. lazydata is primarily designed for machine learning and data science projects. See this medium post for more.

QUESTION
I'm trying to build a package for data visualisation that relies heavily on ggplot2, but has some custom shortcuts for some of the day to day problems I face.
I am able to use ggplot_add function to extend the functionality of + for custom classes from scripts, however when I add these scripts to a package, ggplot_add no longer works.
Below I paste a minrep, to replicate first one needs to create a package (I'm using RStudio), that I've called SOExa. That project contains the following files:
.Rbuildignore
...ANSWER
Answered 2021-May-02 at 06:51This is a common issue that trips me up a lot. You will need to make sure your package has access to ggplot2's ggplot_add generic function. You do this one of two ways.
You will need to include the following line somewhere in your package:

When I run devtools::check on my package locally, I don't get this error, but when I submit my package to CRAN, or when I run devtools::check_win_devel, I get this error:
'LazyData' is specified without a 'data' directory
I successfully submitted my package to CRAN a week or so ago and didn't get this error, all I changed was the DESCRIPTION file.
...ANSWER
Answered 2021-Mar-29 at 19:51Over the course of time, policy settings change. Changes are first implemented in r-devel which is why you see this at win_devel.
This particular change ... was added last week. One way to stay abreast of such changes is to follow the auto-generated 'blog' of changes here https://developer.r-project.org/blosxom.cgi/R-devel/NEWS
I actually just helped a friend on this issue this weekend and took this screenshot from the Feedly RSS feed reader I use:
(The underlining is a formatting artyfact we can ignore).
But in short, you need to check against r-devel, and you actually promise to CRAN each time you upload that you did :)
QUESTION
I tried to add a small C++ function (called reduceString) into an R package of mine using Rcpp but I failed to configurate the package so that it compiles fine. The package can be found here.
ANSWER
Answered 2021-Jan-20 at 13:47Thanks for posting a link to a repo.
It worked for me as soon as I re-recreated RcppExports.{cpp,R} using my (current) version of Rcpp and a call to compileAttributes(). What version of Rcpp do you have?
The log below uses my wrappers from littler but that is immaterial. The R CMD ... commands would have worked the same way.
QUESTION
Rcpp is powerful and has worked great in most all cases, but I cannot figure out how to wrap a C-function that returns a user-defined structure into an R package.

QUESTION
This minimal example compiles when I "source" the file:
...ANSWER
Answered 2020-Jul-04 at 21:26That look like another instance of a not-entirely-uncommon problem for which we do have a wonderfully simple answer that is somewho less known than it should be.
In short, for a package (where is an alias for your package name, with lower or undercase as you please. and obviously no < or >) please such struct (or in the C++ case class) or typedef or ... definitions into a file inst/include/_types.h (replacing with your package name).
If such a file exists, it is automagically included by RcppExports.cpp and you are good to go.
Details are in the Rcpp Attributes vignette, and a few related forms are allowed as well:
QUESTION
When I try to install my GitHub package, this error occurs with lazydata. My csv files are in the "data" folder. I believe that the error may be there, but not yet what it is.
...ANSWER
Answered 2020-Jun-23 at 15:37This is because you have the data folder in the root of your repository and it is filled with csv files. You are supposed to use the rda format for any files in that folder. If you want to use csv files with your package, put them in inst/extdata.

QUESTION
I need to lazy load some infinite streams because they are expensive to start. And I also don't ever want to stop them once they are started for the same reason.
I'm thinking it would be neat if there was a share operator that didn't unsubscribe from the underlying stream ever once it is subscribed for the first time, even when all downstream subscribers unsubscribe.
Right now I'm doing it with a publish and a connect on two different lines, which works alright but just seems clunky and not very rxjs like:
...ANSWER
Answered 2019-Dec-11 at 01:17The shareReplay operator was added in RxJS version 5.4.0. And, in version 5.5.0 a bug was fixed so that it maintains its history when its subscriber count drops to zero.
With the fix, shareReplay will effect the behaviour you are looking for, as it will now unsubscribe from the source only when the source completes or errors. When the number of subscribers to the shared observable drops to zero, the shared observable will remain subscribed to the source.
The behaviour of shareReplay has changed several times and a summary of the changes - and the reasons for them - can be found in this blog post.
