QUESTION
I'm trying to use the tidyverse to make a function that allows me to take a vector of column names (of class factor), count how many observations meet a certain condition (value == "yes"), mutate()
and make new columns using this sum so I can summarise the data later.
I have written a function that can do this for a single column, but I want to be able to pass a vector of column names of any length using all_of()
grammar to the function. When I try this, I get a new column with the same name as the vector (including my _count
suffix) not the values inside the vector.
This is similar to TimTeaFan's Post but I would like to pass a vector where length > 1.
I think I might need to use the (. . .) option in dplyr and some more rlang, but I haven't quite figured out the right combination. The function doesn't work when I substitute (. . .) for objective thanks to NSE. I've also tried variations of rlang::as_name()
and rlang::get_env()
. There was an outdated workbook that used purrr::map()
as well, but I haven't had any luck implementing it here.
I either got Error: Column x
is not found.
or Error: Promise has already been forced
Here is a reproducible example with data

across
the columns and get sums for each category.

I'd like to write a function in R for making some graphs and, optionally, facetting those graphs by whatever column the user inputs. I'd prefer to do this using nonstandard evaluation since I don't know what columns the user will have in the data.frame that they input. The code below works, and the user can specify what column they want to color points by:

QUESTION
I have been learning buffer overflows and i am trying to execute the following command through shellcode /bin/nc -e /bin/sh -nvlp 4455
. Here is my assembly code:
ANSWER
Answered 2021-Dec-29 at 14:12As you can see in strace
, the execve command executes as:
execve("/bin//nc", ["/bin//nc", "/bin//nc-e //bin/bash -nvlp 4455"], NULL) = 0
It seems to be taking the whole /bin//nc-e //bin/bash -nvlp 4455
as a single argument and thus thinks it's a hostname. In order to get around that, the three argv[]
needed for execve()
is pushed seperately.
argv[]=["/bin/nc", "-e/bin/bash", "-nvlp4455"]
These arguments are each pushed into edx, ecx, and ebx. since ebx needs to be /bin/nc, which was already done in the original code. we just needed to push 2nd and 3rd argv[] into ecx and edx and push it into stack. After that we just copy the whole stack into ecx, and then xor edx,edx
to set edx as NULL.
Here is the correct solution:

I have trained my stock price prediction model by splitting the dataset into train & test. I have also tested the predictions by comparing the valid data with the predicted data, and the model works fine. But I want to predict actual future values.
What do I need to change in my code below?
How can I make predictions up to a specific date in the actual future?

Below is the exact string value in contract_details
for anyone to try:
ANSWER
Answered 2021-Nov-21 at 10:35As the error message Expecting property name enclosed in double quotes
suggests , json
expects strings to have double quotes around the values inside the string. You can change the source if possible or replace the single quotes with double quotes using replace("'", '"')
on contract_details
, you also need to replace 'nan'
with 'NaN'
