QUESTION
I want to use google streetview in my r shiny application. I am using leaflet to draw my map. I found this great leaflet plugin "Leaflet Pegman".
How do I implement this plugin into a r shiny app?
I tried to use this explanation. I also found another R-package (googleway) but in my case I want to use leaflet instead.
Could some one provide me a working example. This is my code now:
...ANSWER
Answered 2020-Sep-02 at 11:20I had to include the leaflet-pegman js file in the head of the UI for it to work. I also edited the link in the htmlDependency as it wasn't referencing the correct link.
This code works for me now:
QUESTION
Using the google_directions function from googleway package, it does not display the travel time according to google maps browser search.
It seems that it is not taking into account the traffic information.
Example on a busy street in New York.
...ANSWER
Answered 2019-Dec-04 at 15:53The googleway documentation for google_directions covers this. To get real-time data, you need the following:
- a
departure_time, either current using"now"or a specified future time using aPOSIXctdatetime. traffic_model: Whether Google's guess should bebest_guess,optimistic, orpessimistic.
You asked for a historical travel time with your code, while Google Maps use the real-time travel time (likely the best_guess estimate).
The Google documentation states:
best_guess(default) indicates that the returnedduration_in_trafficshould be the best estimate of travel time given what is known about both historical traffic conditions and live traffic. Live traffic becomes more important the closer thedeparture_timeis to now.
Try this instead:
QUESTION
I've a data frame with locations and I want to append phone numbers and websites to them from Google Places in a pipeable solution.
The closest I've gotten to doing this was using googleway, unlisting the JSON and using regexes to extract the place id, and doing the same again for the phone numbers and email addresses. Is there a more targeted way of doing this?
ANSWER
Answered 2019-Jun-12 at 16:56I doubt there is. It is a two step process at the side of Google API (see the documentation: https://developers.google.com/places/web-service/details):
You need to :
- get the unique
placeid(via Place Search call) - get the contact details for your
placeid(via Place Details call)
You might have more control over the process if you pasted your url yourself and executed it via httr (the Google API is known for breaking changes, and hard for R packages to keep pace with) and you can wrap the ugly piece of code in your own function, making the call tidy - but ultimately it will have to be 2 API calls.
QUESTION
I have read Batch Geocoding with googleway R
I am attempting to geocode some addresses using googleway. I want the geocodes, address, and county returned back.
Using the answer linked to above I created the following function.
...ANSWER
Answered 2018-Jul-26 at 17:10Ok, I'll answer it myself.
Begin with a dataframe of addresses. I called mine "addresses" and the singular column in the dataframe is also called "Addresses" (note that I capitalized it).
Use googleway to get the geocode data. I did this using apply to loop across the rows in the address dataframe

QUESTION
I am trying to put a shinydashboard together and have a Google Places Search box as a text input. The code below runs in a regular shiny page, but throws an InvalidValueError: not an instance of HTMLInputElement error when it's put into a shinydashboard. (See image below)
I'm not sure why it would work in a regular shiny app but not inside a shinydashboard.
Minimal reproducible code example:
Note: Plug in your Google API key first
...ANSWER
Answered 2019-Feb-26 at 19:51The only way I have been able to do this is by taking all the logic behind rendering the sidebarMenu out of the server.R file and putting it into the ui.R file.
The final working solution is this:

QUESTION
I have 2 data frames with the geocoded locations of several hospitals within the United States. I would like to plot these locations as markers with two different colors for each set of hospitals from each data frame. I am using the R googleway library and I can get the first set of hospitals to plot okay with a default red colored marker but when I try to change the color of the marker by defining the colour variable with the column names "col", I get the following error message "Error in markerColourIconCheck(data, objArgs, colour, marker_icon) : colours must be either red, blue, green or lavender"
The column "col" is "green" in every row. I tried filling in the hexadecimal color for green in the column "col" as well. so this piece of code works with red markers

Answered 2018-Dec-18 at 19:34I just ran this code and it worked
QUESTION
Not sure why I keep getting this error:
Error in value[3L] : There was an error downloading results. Please manually check the following URL is valid by entering it into a browswer. If valid, please file a bug report citing this URL (note: your API key has been removed, so you will need to add that back in)
...ANSWER
Answered 2018-Nov-06 at 23:15You want to check that you don't have any illegal or reserved characters in your addresses, since any geocoding functions will be using your text to create URLs to query the geocoding API. google_geocode on its own doesn't give a very helpful error message, but by looking at the URL you posted above, the error message shows that the required parameters weren't included.
In this case, # has a special meaning in URLs, so you'll get an error. FYI, my Google API key is saved as the environment variable GOOGLE_KEY:
