QUESTION
I have a dataframe like so:
Child Parent Roots 2 1 [1,3,4] 2 3 [1,3,4] 2 4 [1,3,4] 5 2 [1,3,4] 6 5 [1,3,4]The first 2 fields represent a parent child relationship while the roots field represent the root parents for each row and is stored as a list
due to the possibility of there being several.
I am trying to create a new field that would indicate whether the parent ID is one of the root parent like so:
Child Parent Roots RootParent 2 1 [1,3,4] True 2 3 [1,3,4] True 2 4 [1,3,4] True 5 2 [1,3,4] False 6 5 [1,3,4] FalseHowever, I am not sure how to apply the "any" logic correctly through the list comprehension, here are 2 methods I have tried thus far:

QUESTION
I am currently learning DirectX 12 and trying to get a demo application running. I am currently stuck at creating a pipeline state object using a root signature. I am using dxc to compile my vertex shader:
...ANSWER
Answered 2021-Jun-14 at 06:33Long story short: shader visibility in DX12 is not a bit field, like in Vulkan, so setting the visibility to D3D12_SHADER_VISIBILITY_VERTEX | D3D12_SHADER_VISIBILITY_PIXEL
results in the parameter only being visible to the pixel shader. Setting it to D3D12_SHADER_VISIBILITY_ALL
solved my problem.
QUESTION
I have a table with 2 ID fields like this, where it is possible for a parent to be linked to itself:
Child Parent 1 1 2 1 3 1 4 2 5 3I created a digraph using networkx and am now trying to write a function to identify all the roots and leaves for each row and adding them back to the original dataframe:
...ANSWER
Answered 2021-Jun-11 at 22:14Yes. Accessing the DiGraph as a dictionary with the node as the key will return an AtlasView, which gives all the edges from that node. e.g.
QUESTION
I am writing a math paper where i would like to display my calculations (formulas) separately from the solution.
I am currently working in Google Sheets.
The end goal would be to have one column with formulas and one column with answers.
I tried to work with GS to write a function that would take the string value from A1 and evaluate it in the B1 column.
I used this simple script that i found on: https://support.google.com/docs/thread/13826624/evaluate-string-as-formula?hl=en
...ANSWER
Answered 2021-Jun-12 at 17:58The easiest solution would probably be to work the other way around: write your formulas normally, and use the formulatext()
spreadsheet function to display the formula in an adjacent cell.
QUESTION
I would like to get some basic sense of putting all the data manipulation steps within the reactive session. The reason I have to do this is because the input files are reactive so they made all the new created data frames be reactive as well.
It is not working when outputting the combined dataset from 2 dynamic input sas datasets.
DAT_A:

Answered 2021-Jun-12 at 01:49You can use one fileInput
with multiple=TRUE
or two separate ones with multiple=FALSE
. The code below shows the latter way to do it.

Install roots
You can use roots like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
