kandi X-RAY | jug Summary
jug is a small web development framework for R which relies heavily upon the httpuv package. It’s main focus is to make building APIs for your code as easy as possible. jug is not supposed to be either an especially performant nor an uber stable web framework. Other tools (and languages) might be more suited for that. It focuses on maximizing the ease with which you can create web APIs for your R code. However, the flexibility of jug means that, in theory, you could built an extensive web framework with it. Check out for the vignette documentation.

QUESTION
I have a simple test project at https://github.com/jh3010-qt-questions/font_test
When I build it, I get the error:
qrc:/main.qml:5 module "Fonts" is not installed
My directory structure looks like:
...ANSWER
Answered 2021-Mar-06 at 09:17As described here, the module has to be available in the QML engine's import path:
To define a module, a developer should gather together the various QML documents, JavaScript resources and C++ plugins which belong in the module into a single directory, and write an appropriate module definition qmldir file which should also be placed into the directory. The directory can then be installed into the QML import path as a module.
You can do this by calling addImportPath() with the path to the parent directory of the directory that contains the qmldir
. When you import your module with

I am running a Monte Carlo in Excel. To represent the distribution of demand for each product SKU during each month, I am using the following formula over 500 times:
=IFERROR(BETA.INV(RAND(),(1+4*(D35-D31)/(D27-D31)),(1+4*(D27-D35)/(D27-D31)),D31,D27),0)
So, that's over 500 RAND()
volatile functions at a time.
The output from each iteration of a formula is stored in a table. I have a VBA to handle that:

QUESTION
I am looking at production data from a manufacturing facility and need to classify the day's production for all production lines based on the size of bottle produced on one line. The basic setup is that line FL 5S only produces 5l jugs, FL 25 produces 25l jugs, and FL 5 can produce 1l, 3l, and 5l jugs. I need a new column called "Recipe" which should reflect the size of jug produced on FL 5 for all orders on any line produced concurrently with orders produced on FL 5. For example, if Size == "001"
over the time interval 2020-04-28 08:46:56 UTC--2020-04-29 07:49:09 UTC
then Recipe
should be 001
for all orders produced on the other lines whose Started
and Ended
times overlap with these times for the 1l order.
Data:
...ANSWER
Answered 2020-Dec-19 at 00:50I am not sure how you want to deal with overlaps with several FL 5
orders and non-existing overlaps, but you can modify the approach below to fit your needs.
I used foverlaps()
from the data.table
package to identify overlaps. You can use the type
parameter if you want to specify interval overlaps (e.g. fully within, start or end overlap).
QUESTION
I'm trying to combine multiple URLs parameters under one joined link. Console log registers all of the parameters, my issue is that stored value is overwritten and only last value is being printed as well as the number of printed parameters is not matching to the actual amount of URLs. I've included code below:
...ANSWER
Answered 2020-Dec-18 at 02:59As for only printing that last value, when you call text()
every iteration then it overwrites whatever was previously in that element.
Following simplifies both reading existing params and generating combined ones by using URLSearchParams() API. It also generates an array of the values that are easily inserted in the
using join()

I'm attempting to read a line from a file and return a pointer to the beginning of the next line but I don't understand what's happening to the fd when I use it to read 10 chars at a time. I'm only able to use read, write, open and malloc.
Example file.txt (with \n
being shown explicitly):
ANSWER
Answered 2020-Apr-23 at 18:17You're talking about the file offset. To your first question, yes, you're correct about where the offsets are at that point. To your second question, you can use lseek
to move the offset back. To go back 2 characters, you'd do lseek(fd, -2, SEEK_CUR)
