#### Distance between two locations - Google Maps

I'm trying to find the location between two points using google maps. Here is the code that I'm working with: function initialize() { var myOptions = { center: new google.maps.LatLng(36.8813329,-103.6975488), zoom: 4, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.

#### Visualizing distance between nodes according to weights - with R

I'm trying to draw a graph where the distance between vertices correspond to the edge weights* and I've founde that in graphviz there is a way to draw such graph. Is there a way to do this in R with the igraph package (specfically with graph.adkacency)? Thanks, Noam (as once have been asked: draw a graph where the distance between vertices corr

#### Calculate distance between two vectors of different length

There are different methods to calculate distance between two vectors of the same length: Euclidean, Manhattan, Hamming ... I'm wondering about any method that would calculate distance between vectors of different length. Solution The Euclidean distance formula finds the distance between any two points in Euclidean space. A point in Euclidean sp

#### Calculating all distances between one point and a group of points efficiently in R

First of all, I am new to R (I started yesterday). I have two groups of points, data and centers, the first one of size n and the second of size K (for instance, n = 3823 and K = 10), and for each i in the first set, I need to find j in the second with the minimum distance. My idea is simple: for each i, let dist[j] be the distance between i and

#### Percentage rank of matches using Levenshtein Distance matching

I am trying to match a single search term against a dictionary of possible matches using a Levenshtein distance algorithm. The algorithm returns a distance expressed as number of operations required to convert the search string into the matched string. I want to present the results in ranked percentage list of top "N" (say 10) matches. Since the

#### Mahalanobis distance in R

I have found the mahalanobis.dist function in package StatMatch (http://cran.r-project.org/web/packages/StatMatch/StatMatch.pdf) but it isn't doing exactly what I want. It seems to be calculating the mahalanobis distance from each observation in data.y to each observation in data.x I would like to calculate the mahalanobis distance of one observa

#### How do I find the difference between two values without knowing which is larger?

I was wondering if there was a function built into Python that can determine the distance between two rational numbers but without me telling it which number is larger. e.g. >>>distance(6,3) 3 >>>distance(3,6) 3 Obviously I could write a simple definition to calculate which is larger and then just do a simple subtraction: def

#### Convert a dataframe to an object of class "dist" without actually calculating distances in R

I have a dataframe with distances df<-data.frame(site.x=c("A","A","A","B","B","C"), site.y=c("B","C","D","C","D","D"),Distance=c(67,57,64,60,67,60)) I need to convert this to an object of class "dist" but I do not need to calculate a distance so therefore I cannon use the dist() function. Any advice? Solution I had a similar problem not

#### Using Dispose() method

Why I see "Hello" words many times when I add timer.Dispose() to my code in release mode. Without timer.Dispose() I see "Hello" once. Thanks. using System.Threading; namespace ConsoleApplication1 { class Program { static void Method(object state) { Console.WriteLine(state); GC.Collect();

#### Is Close() same as Using statement

Is Close() same as Dispose() or using statement. Is it necessary to call using statement even if Close is called?. I know before disposing of an object, close should be called, so we close the resource and may it available to Dispose. https://msdn.microsoft.com/en-us/library/aa355056(v=vs.110).aspx says Close is same as Dispose. Solution Close(
