What is happening during assignment to a dataframe by lapply

Asked 2021-Apr-23 at 16:31

Given a dataframe df and a function f which is applied to df:

df[] <- lapply(df, f)

What is the magic R is performing to replace columns in df with collection of vectors in the list from lapply? I see that the result from lapply is a list of vectors having the same names as the dataframe df. I assume some magic mapping is being done to map the vectors to df[], which is the collection of columns in df (methinks). Just works? Trying to better understand so that I remember what to use the next time.

A data.frame is merely a list of vectors having the same length. You can see it using is.list(a_data_frame). It will return TRUE.

[] can have different meaning or action depending of the object it is applied on. It even can be redefined as it is in fact a function.

[] allows to subset or insert vector columns from data.frame.

df[1] get the first column df[1] <- 2 replace the first column with 2 (repeated in order to have the same length as other columns)

df[] return the whole data.frame df[] <- list(c1,c2,c3) sets the content of the data.frame replacing it's current content

Plus a wide number of other way to access or set data in a data.frame (by column name, by subset of rows, of columns, ...)

How to make Git commit hash available in C++ code without needless recompiling?

Asked 2019-Oct-09 at 19:31

A fairly common requirement, methinks: I want myapp --version to show the version and the Git commit hash (including whether the repository was dirty). The application is being built through a Makefile (actually generated by qmake, but let's keep it "simple" for now). I'm fairly well versed in Makefiles, but this one has me stumped.

I can easily get the desired output like this:

ANSWER

Answered 2018-Aug-08 at 08:30

First of all, you could generate a phony version.h but use it only in version.cpp that defines the print_version function used everywhere else. Each invocation of make while nothing changed would then cost you only one ultra-fast compilation of version.cpp plus the fairly lengthy link stage. No other re-compilations.

Next, you can probably solve your problem with a bit of recursive make:

Difficulty positioning heatmap.2 components

Asked 2019-Apr-23 at 21:57

I have been really struggling to position the components of my heatmap.2 output.

I found this old answer explaining how the element positioning worked from @IanSudbery which seemed really clear and I thought it had given me the understanding I need, but I'm still not grasping something.

I understand that the elements are all essentially put in a lattice of windows but they aren't behaving in a way I understand.

Here is my code and the current output (at the very bottom is the bit of interest which orders the figure elements):

I don't know if you're open to non-heatmap.2-based solutions. In my opinion ggplot offers greater flexibility and with a bit of tweaking you can reproduce a heatmap similar to the one you're showing quite comfortably while maximising plotting "real-estate" and avoiding excessive whitespace.

I'm happy to remove this post if you're only looking for heatmap.2 solutions.

That aside, a ggplot2 solution may look like this:

ASP.NET MVC Bad Practices: Controller Action Not Restricted to POST - False Alarm?

ASP.NET MVC Bad Practices: Controller Action Not Restricted to POST

...

ANSWER

Answered 2018-Sep-04 at 17:53

I'd suggest it probably is a false positive if you aren't modifying the data. The Fortify explanation for that states (my emphasis)

ASP.NET MVC controller actions that modify data by writing, updating, or deleting could benefit from being restricted to accept the POST verb. This increases the difficulty of cross-site request forgery because accidental clicking of links will not cause the action to execute.

From your method signature, it looks like you are returning data based on the request rather than modifying it, so I think in your case, it could be considered a false positive.

QUESTION

Does V8 have an event loop?

Asked 2018-May-01 at 18:05

I keep hearing V8 has its rudimentary event loop implementation but

couldn't find it
doesn't really make sense to me. Methinks, the simplest design of a JS engine would be to simply run synchronously and let the "embedder" write their own event loop - like nodejs got libuv.

Is there an event loop implementation in v8? If so, could you point me at it?

...

ANSWER

Answered 2018-May-01 at 18:05

Your intuition is right that the event loop is something that embedders should have control over. However, it is also a fundamental abstract concept of the JavaScript programming model. V8's solution is to provide a default implementation that embedders can override; you can find it in the "libplatform" component: https://chromium.googlesource.com/v8/v8/+/master/src/libplatform/default-platform.cc#140

LWJGL - ArrayList empty after generating tiles, and quad failing to be added on mouse click

Asked 2018-Jan-24 at 05:29

So I have two issues with this code right now. I also do have a question, edited to be at the end.

When i generate tiles, it seems that my arraylist i add them to, appears empty when i read it, I do read it after I finish generating it, so it shouldnt appear empty, and they do get added from what I see. Anyone know whats wrong?
Also i have a function on my left mouse click to add a quad at the location, which gets added to the drawQuads list and then rendered, it seems that it should be in order? The very same list does add the other quads correctly and renders them just fine.

If it matters, I'm using netbeans. Been grinding away at this for awhile now, I actually made the generator while thinking about how to fix the quad issue and then I hit another one so I figured it would be time for some help.

ANSWER

Answered 2018-Jan-24 at 05:29

So! I actually figured out a janky way to fix the issue- moving the generator code into my render class - albeit this was just a workaround, but then i went to check up on this and i see the delightful "alex" having answered the question with what i was going to ask specifically.

The issue was; The instance itself seemed to be initialized twice, while it should have just used the same instance(?) it apparently decided not to. So now i just gotta find a way to use the same instance and transfer it over. Thankyou all for the help! I wish i could contribute this answer to alex, but im not sure how to upvote or set a comment as an answer?

So theres the fix if anyone runs into this same issue! Its probably using several instances.

Here is a good way to resolve it for anyone else! Its what i used. Java: Using same instance of a class in various other classes
