QUESTION
I'm in the tidyverse.
I read in several CSV files using read_csv (all have the same columns)
ANSWER
Answered 2019-Dec-17 at 10:31I think the important point is that the columns start and stop, which appear to be of type time, are based on the hms package. I wondered why/when is displayed, becauses I had not heared about this class before.
As I see it, these columns are actually of class hms and difftime. Such objects are actually stored not in minutes (as the printed tibble suggests) but in seconds. We see this if we look at the data via View(df). Interestingly, if we print the data, the variable type is displayed as time.
To solve your problem, you have to convert all your start and stop columns consistently into hms difftime columns as in the example below.
Minimal reproducible example:
QUESTION
I've got a webapp using Accusofts Prizm ActiveX Viewer to view and edit PDF's online. This product seems to work fine in every browser including edge except, you guessed it, Internet Explorer 11. I have been searching through the depths of the internet to try to find a solution to this and have found no useful results.
The error I am receiving is SCRIPT5022: SyntaxError with no further information on the error received which takes me to the following function with the 3rd line being the recipient of the error.
function createIconMap(iconText) {
var parser = new DOMParser();
var iconDoc = parser.parseFromString(iconText, 'image/svg+xml');
I have ran and compared IE against chrome and both inspectors are informing me they are behaving the same. Yet IE brakes on this function and Chrome goes on to display the PDF.
Please see the full JS below

Answered 2018-Oct-31 at 07:48Please check the file (pdf, xml) content, might be the file contain the error description. More details, you could refer to this sample.
Besides, according to this thread, you could try to use ActiveX to parse documents.
QUESTION
My app being developed using mvvm pattern & I am not sure that what pattern I am using? Some of mvvm pattern are out there like
- mvvm fresh
- mvvm light
- mvvm prizm
to name a few. This is my mvvm class
...ANSWER
Answered 2018-Sep-24 at 15:22You are learning the Xamarin Forms platform. You are using the existing Xamarin Forms based Navigation. You are implementing INotifyPropertyChanged (to notify changes to your View when your Model changes) in every Models/ViewModels for now. Yourself Binding the Binding Context for all the pages you have! All those libraries you referred to are the Libraries to help you implement the Navigation, MVVM, IOC etc.
You are implementing parts of the features those libraries provides. Then why do you need to think about them? The more bigger your apps become and more works you do manually to manage many of the features they provide - is time consuming. Eventually, you want to use all of those features that some of those libraries provides!
So, using one of those libraries, You will save a lot of time and cost. Commonly all of these MVVM Libraries provides the Features like :
- IOC
- Automatic ViewModel Binding
- ViewModel supports the page events like appearing/disappearing
- ViewModel to ViewModel navigation
- Built in INotifyPropertyChanged in form of BaseViewModel
- Supports multiple navigations like MasterDetail navigation, Tabbed navigation etc.
Confused about the Pattern? Pattern is a COMMON WAY of implementing the System. Every part of the system follows some common rules in term of Names, Accessibility, Implementation etc. Using those libraries, you will follow all/any of the System/Rules/Pattern they offer in form of that Library. All of them Support MVVM which means that, all of your Pages should have their ViewModel. All of your Logics and Data related to that View should Go inside the ViewModel rather than you will Mixup.
It's all your choice whether or not to use those libraries. But, using any of those, you will build the great app that follows the Separation of the parts/concern of the app being developed in cleaner way.
QUESTION
I'm just starting to learn shiny, and I've been having an issue with just viewing the uploaded csv. I was able to view the data when I didn't have a sidebar menu, but now that I am trying to expand on my app with other tabs, the data does now show up. Is there something wrong with my formatting? My code is attached, and it could be used for any csv. Thanks

Answered 2017-Nov-13 at 06:00It's just a typo in your code in tabName (notice the capital N) within the menuItem:
QUESTION
I've been tasked with hard-coding enhanced ecommerce tracking to a website (without the use of any tag management). The task is to simple include 'add to basket'.
It's expected that I define the data fields with some variables, rather than a string.
So, given this web page, would the following script pull the relevant data I'm expecting? (SKU, Product name, price and quantity selected)
...ANSWER
Answered 2017-Jul-07 at 15:18All of your snippets above return errors when I run them on the page, so I would make the stab that they do not currently work.
The easiest way to confirm is to open the webpage in your web browser, and then try running the snippets in a javascript console (e.g. cmd+alt+j in Chrome for Mac).
If you can, it is almost certainly better to scrape by id or by name, because these are less likely to change for frivolous reasons - class is primarily for style and so it is very likely to change when the page style does.
Class name and name refer to different parts of the html element:
