R - Removing rows from one table based on unique combination from another table

Asked 2021-Jun-14 at 17:19

I have two tables. Table A - Base table with full data. Table B - Contains grouped data by the combination (Origin- Destination- Carrier- Class). It has only those combinations which have both Premium and Economy class and also greater than 100 passengers each.

My objective is to only include those rows in Table A which pertain to combinations in Table B. Sample tables are below -

Table A

ItinID Origin Destination Carrier Class Fare 1 AB BC Delta Econ 100 2 AB BC Delta Premium 500 3 CD DE American Econ 200 4 EF FG United Econ 200 5 AB BC Delta Econ 150 6 AB BC Delta Premium 700

Table B

Origin Destination Carrier Class AB BC Delta Econ AB BC Delta Premium

The output table that I need is-

ItinID Origin Destination Carrier Class Fare 1 AB BC Delta Econ 100 2 AB BC Delta Premium 500 5 AB BC Delta Econ 150 6 AB BC Delta Premium 700

Also, is there a way to skip making Table B altogether and directly running operation on Table A to get the output table?

Thank you

1) Here are base, dplyr and sqldf solutions. We join A and B and then sort by ItinID (although it seems that the dplyr solution is already sorted that way so we omit that part for it).

QUESTION

Is it possible to prevent the Json.Net TypeNameHandling vulnerability with a marker for trusted types?

Asked 2021-Jun-12 at 08:36

I was reading about the vulnerability of deserializing types with Json.Net using a setting different from TypeNameHandling.None. The Json.Net docs recommend implementing a custom SerializationBinder. A simple example of a custom binder that checks types against a list of known types is given here.

While this solution certainly works, the set of known types is not fixed in my scenario, since the application has to support extensions, which might define their own data classes. One solution would be to extend the known type list during the registration of an extension, however, I had a second approach in mind, that I'd like to verify:

I want to define a common interface for trusted types:

(suggested by dbc: A custom attribute could be used instead of a marker interface.)

ANSWER

Answered 2021-Jun-11 at 15:15

When you encounter a type that isn't marked, it is not sufficient to check its generic type arguments, you need to check the type of every public property and every parameter of a public constructor, because these are the serialization footprint.

For example, you really do not want to allow deserialization of a System.Data.TypedTableBase even if T is safe, because it has public properties that allow configuring database access.

QUESTION

Correct usage of modulo operator's in C++

Asked 2021-Jun-12 at 03:44

I am trying to teach myself c++.

On Sololearn I have a task, which is

You are making a program for a bus service. A bus can transport 50 passengers at once. Given the number of passengers waiting in the bus station as input, you need to calculate and output how many empty seats the last bus will have.

Sample Input: 126

Sample Output: 24

It also says I should use the "%" operator. This is the code I created:

...

ANSWER

Answered 2021-May-09 at 14:22

Modulos operator basically represents the leftover from the division

so what we need to do is take the number of people that will remain in the last bus travel which is stop % bus and compute bus - (stop % bus)

that way we know the number of empty seats on the last travel

This is like each bus was filled to the fullest (50 people per bus) what will remain is 26 and so on the last bus the number of empty seats will be 50 - 26 = 24

PS: 12 doesn't seem to be the right output of 126 % 50 it should be 26

QUESTION

group by id1 and id2 and apply a function using another dataframe and dates

Asked 2021-Jun-11 at 11:24

My problem is the following: I have a dataframe DF1 of car accidents (id_accident) and PASSENGER victims (id_victim) and the date of the accident (date1).

id_accident id_victim date_accident ROL 123 23A 2021/20/01 PASSENGER 456 12B 2020/19/08 PASSENGER 111 41A 2021/20/01 PASSENGER 222 54B 2020/19/08 PASSENGER

I have another dataframe DF2 of the same car accidents and more (id_accident) and VICTIMS in general (could be ROLE_VICTIM = PASSENGER or DRIVERS) and the date of the accident (date1)

id_accident id_victim date_accident ROL 001 23A 2020/20/19 PASSENGER 002 12B 2019/31/12 DRIVER 003 41A 2020/20/12 PASSENGER 004 54B 2020/20/07 DRIVER

So, I need to find for each id_accident and id_passenger if this passenger had a previous accident within last 3 months but now as ROLE_VICTIM =DRIVER.

My code consists in two loops and a function that searches the previous accidents when the victim of this accident was a driver in the previous one.

This looks like classic SQL question. What kind of output format do you need?

I had to change first date if DF2 to 2020/20/01 to make pandas recognize it. Below is the complete example using pd.merge

You can sort objects in a list with the sort method (https://docs.oracle.com/javase/8/docs/api/java/util/List.html#sort-java.util.Comparator-). To compare them you can use the 'Comparator' class (https://docs.oracle.com/javase/8/docs/api/java/util/Comparator.html):

QUESTION

Why does the error message not show for the first try, but works fine for the other?

Asked 2021-Jun-09 at 15:44

Can someone please tell me why the first try catch is not showing an error message when the user inputs invalid format of data, i.e inputs integar instead of string. If I input numbers instead of letters, the program just accepts it and moves forward. The other try catch for age is working fine.

...

ANSWER

Answered 2021-Jun-09 at 15:44

The first try/catch block is working properly as well. It's up to you, the developer to determine what value a string can contain in order for it to be valid or invalid.

In terms of the language, both "john doe" and "123151" are valid strings (the second one is just a string representation of digits). Keep in mind that the code interprets these two very differently:

"123151"
123151

The first is a string with the value "123151". The second is an integer with the value 123151.

When you read from the console.ReadLine() function into a string variable, you will get a string value of whatever value is input.

What I would suggest, moving forward, is that you add some sort of programming to verify that the value that is input is more like the value your program is expecting. For example, if you're not expecting the string to have any numbers in it, you could check the string for integer values, and throw the exception if any are found. You might even use Regular Expressions to help identify integers or other invalid values.
