I am using the R package, gmapsdistance, to extract Google distance matrix.
My codes are:
gdm <- gmapsdistance(origin = origin_vector,
destination = destination_vector,
combinations = "pairwise",
mode = "driving",
shape = "long",
dep_date = date_vector,
dep_time = time_vector)
The Google API key was also set. The code works until the parameters for dep_date and dep_time. I believe it is because the parameters do not accept vectors. Two errors appear:
1: XML declaration allowed only at the start of the document.
2: Extra content at the end of the document.
In my dataset, each row is a data point with a unique origin, destination, departure date, and departure time. I require the Google distance/time for each row and there are thousands of them. There is no need for me to compare across rows. How may I do this?
Appreciate any help!
