pomp | Screen scraping and web crawling framework | Crawler library

As an intern, I have to scrape the price of a product sheet on a site. But the div contains multiple spans with prices and only one contains the actual price that is displayed. Their absolute left position changes with each refresh. So when I do something like $productPrice $packtPageXpath->query('//div[@class="bloc_price"]'); if ($productPrice->length > 0) { $productSheet['name'] = $productPrice->item(0)->nodeValue; this returns me the list of all the prices in a different order at each refresh in the array

Here is an example of a product sheet https://www.pompes-direct.com/pompage/pompe-electrique/surface/jet/jet-102-t/4432.html

Simulating an SIR model in R. I have a data set I am trying to plot accurately with the model. I am right now using the particle filter function, then would like to use the corresponding logLik method on the result. When I do this, I get "[1] -Inf" as a result. I can't find in the documentation why this is and how I can avoid it. Are my parameters for the model not accurate enough? Is there something else wrong?

My function looks like this: SIRsim %>% pfilter(Np=5000) -> pf logLik(pf)

From an online course lesson entitled Likelihood for POMPS https://kingaa.github.io/sbied/pfilter/ , this is the R script for the lesson. However, the code works here... I'm not sure how to reproduce my specific problem with it and unfortunately cannot share the dataset or code I am using because it is for academic research.

I try to model a SEIR for UK to evaluate the implemented containment measures and found some code with the pomp package here: https://kingaa.github.io/clim-dis/parest/parest.html I tried to transfer this to my case which adds one stage (E) and three more variables. In the end i want to do a least squared estimation to find the optimal beta. Data_UK_beta0 consists of the variable date (int from 0 to 165) and new_cases (from John Hopkins University dataset).

i have a website that use bootstrap 2.1.1 and the navbar on mobile device as a bug. When i click on the drop down icon, the navbar open very fast and collapse after that. When i reclick, it open normally, but if i click on the Produits dropdown that i sinside the original one, it open ok but when i click on a link inside this dropdown it seems to click on a link inside the background where another link was before i dropdown the menu. The navbar code is as follow:

I am a newbie R user. Now, I have a question related to write out multiple files with different names. Lets says that my data has the following structure:

first thanks to read this. I did a workout app for my team, inspired by a yoga app tutorial. My problem is in the yoga app you don't have many sets, just one, and i would like to add sets. I tried to make a for(int i = 0; i < 50; i++) in my ShowExercises but it didn't work and i would like to have the exercise and the rest repeated, not just the exercise. Here is my code,

I am struggling to get a good code for below transformation FROM: (S (S (pomp:stem) (ous:suffix)) (ly:suffix))

To: (S (S (STEM pomp) (SUFFIX ous)) (SUFFIX ly))

Stem/suffix/prefix are standard terms while pomp/ous/ly will vary for each word. I have 1000+ such rows which needs to be transformed I tried regex match/findall with series of steps but not getting a clean results. Is there a quick way to solve this?
