kandi X-RAY | benzo Summary
Wrapping Cocaine, this library will greatly simplify building complex and conditional commandline arguments. This is especially useful when creating wrappers for other commandline tools. Benzo 2.x is compatible with the latest version of Cocaine, but due to the way that it works, it requires Ruby 1.9.x unless you use the OrderedHash library.

QUESTION
I have this custom function querying a group by from a datalist. As a result I receive my unique query result but as nested objects [{substance: 'value'}]. It would prefer my response to be [value, value, value].

QUESTION
I am relatively new to R. I have a dataframe that has a column stored as a list. My column contain c("Benzo", "Ferri") or character(0) if it's empty. How can I change them to simply Benzo, Ferri and an empty string for character(0) instead?
I'm not able to, for instance df$general_RN <- unlist(df$general_RN) because Error in $<-.data.frame(*tmp*, general_RN, value = c("Drug Combinations", : replacement has 1992 rows, data has 10479
I am assuming that all the character(0) have been removed but I need them retained as NAs.
Here is what the column looks like

QUESTION
I have an [Available Team] array that populates under (Available Team Members) as buttons. I would like that when one is clicked that it generates a child button under (Alpha Team Members) with the same name of the parent. When the same parent is clicked again I would like the child to be removed from (Alpha Team Members). (Omega Team Members) are randomly generated.
My problem is that the click handlers complete this function for all the buttons at once and not just the one clicked and when clicked it shuffles the randomly generated (Omega Team Members) which it should not do... Help would be appreciated. Thank you in advance.
...ANSWER
Answered 2018-Jan-24 at 14:08I hope i understood you correctly, so here my solution:
Your logic for a dynamic display of the player buttons is missing, you just toggle the buttons on and off. Your handleClick function does not work differently based on which player button you click.
Therefore you have to pass a parameter to the handleClick, i'd suggest the player. Then you need to push each player you want to display in your alphaTeam array. That array has to be displayed in a loop aswell (presumably if you want to display more than one player there).
For the shuffle part, your handleClick function sets the state for your App Component, what causes React to rerender the App, therefore shuffling your OmegaTeam again. You should consider moving the shuffle as well as the initalization of your AvailableTeam in the contructor / state.
Here my suggestions, i didn't test it though:
QUESTION
I have all the files like app.json,Procfile,package.json,server.js in my app folder. Initialized Git,added the changes,made a commit. Then created the heroku, got the online Heroku URL.
But now on hitting the url it says "H81" implying there is no single code in the app that you have created. But I have all the changes pushed, Why is it saying so?
Help me. cheers!

...ANSWER
Answered 2018-Jan-17 at 02:21After adding and committing your changes, you must push them to Heroku. The default command for this, assuming you followed Heroku's instructions for creating a git remote, is:
git push heroku master

Apparently this is not easy! There's got to be a way using pure regex?? I just know there is....
I have found a way to select the text after the first occurrence of a hyphen in a text file

QUESTION
I am relatively new to R. I have a character variable named RN whose text needs to be extracted into 2 variables [named_RN and general_RN] based on some conditions on RN. This is what the desired result is (right now, named_RN and general_RN are blank - I don't know how to code this part and that's what I need help on!):
ANSWER
Answered 2017-Jun-20 at 00:44Wile I did use gsub, I also used string_match_all from the stringr
package. To get around the problem you mentioned (that codes may contain 0), you can just use the \\b assertion to restrict that the 0 is not part of a longer string.
First named_RN

I read many topics how to get data from the website etc., but i can't find a solution to my problem.
So, I am trying to get data from this table: http://www.opole.pios.gov.pl:81/dane-pomiarowe/automatyczne/stacja/118/parametry/461/dzienny/07.02.2017
but every method gives me only html code like this:

Answered 2017-Feb-07 at 18:06I believe the data for that table actually comes from a JSON service.

Install benzo
Given that you want to make a call to pg_dump, but depending on some conditions in your code, you may want to have certain arguments shown or not shown:. Benzo takes 2 arguments: command and options_map. The command is, like in cocaine, the command you wish to run, and options_map is a hash containing the data necessary to build the commandline arguments. Any value in the hash that evaluates to false (this includes nil) will be omitted from the command.
