similar to: computing distance in miles or km between 2 street

Hi R-ers: I need to compute the distance between 2 street addresses in either km or miles. I do not care if the distance is a "shortest driving route" or if it is "as the crow flies." Does anybody know how to do this? Can it be done in R? I have thousands of addresses, so I think that Mapquest is out of the question! Please rely to: philipsmith at alumni.albany.edu Thank

Hi: I have a matrix, named "mat," of numeric values that are in days since Jan 1, 1960. I want to convert them Date class values so that I can do things like seq( value , len=10, by="1 week") where "value" is any of the matrix elements. How do I do this? Please reply to: philipsmith at alumni.albany.edu Thanks! Phil Smith Duluth, GA

Hi R-People: I use 2 machines: a machine with a Windows XP operating system, and another with a Linux Ubuntu OS. I transport my code between these 2 machines. However, pathnames to data files always need to be "adjusted" to account for the OS that I'm working on. Here is my question: How do I write code to detect whether I'm using the XP or the Linux machine? If I knew

This is a patch we had to implement to use custom icons in mapquest. We needed to use a custom icon size and offset, so I added a small bit of code to handle this. We use MapQuest API v5.3. That may make this not work in all cases, I know the icon stuff changed somewhat between 5.2&5.3. To make work on MapQuests 5.2 API, I *think* would only take the following conversions. 1) MapIcon

Hi, I''m using mapstraction with Google Maps api and I want to use routes. As of now, mapstraction only supports mapquest API to do this, so can I use the underlying googlemaps API to do this, while using mapstraction? If yes, how? Btw, mapquest route demo doesn''t work (Error: MQA is not defined / Source File: http://mapstraction.com/mapstraction-js/mapstraction.js / Line: 621)

Hi to all! Well, I''ve been trying to find a solution to route using known LatLng points - I already have the location position, all I needed was the actual route, so I''ve put together an addition to the "mapstraction-route.js". I''ve listed it below, so maybe it would not be a bad idea to merge it to the trunk... Also, I have a few other questions regarding

Hello, I''m trying the mapstraction library and the swap method. i noticed some strange behavior when swapping from api to another. Here is my page test url http://labomedia.lobotomie.org/~maps/mapstraction/un.html and the trange things : swapping to google is ok ( *but marker disappear* ) *swapping to yahoo don''t work* *swapping mapquest give me a components error in

Can anyone please hazard a guess at an estimate for a poor old squirrel hunter with a Very Very Dumb Question? Is wine likely to be able to install and run any of the proprietary GPS-interfacing topo map programs (DeLorme, Garmin, Mapquest, et al.) at any roughly predictable future date? The season opens in three weeks, my GPS (Garmin's etrex vista) is full -- and it still contains road maps

hey guys, I am trying to add mapping functionality to the example application from the book. The mapping (mapquest''s openAPI) uses javascript to generate maps. So I was thinking that I''ll have a partial view to which i''ll pass the addresses and it''ll plot them. I''ll then put the partial view in the main view. Is this a good way of implementing this

Using Achim's d this also works to generate z where FUN is a function used to transform the index column and format is also passed to FUN. z <- read.zoo(d, index = "time", FUN = as.yearqtr, format = "Q%q %Y") On Sun, Jan 28, 2018 at 4:53 PM, Achim Zeileis <Achim.Zeileis at uibk.ac.at> wrote: > On Sun, 28 Jan 2018, phil at philipsmith.ca wrote: > >> I

I''m trying to include all the map types on the same page and I''m seeing some pretty weird behavior. 1. When the map quest JS file is included, many other maps including Microsft, Map24 stop working. The shell of the map is displayed with the map type logo, but no map. and occasionally an error for (var i = 0; i < me.onload[api].length; i++) { me.onload[api][i](); }

Several map providers have functions to pan to a location, as opposed to the direct setCenter call. Panning animates the move from one point to another. To implement this in mapstraction, I created a panCenter function. I don''t know how to go about committing the change to svn, or who decides whether my naming convention is worthy, but I thought I''d share the function

How can I compute pairwise p-values in Kaplan-meier plots for three or more groups? bin.1<-cut(score,c(-1000,-1,1,1000),c("low","intermediate","high")) I use "km.coxph.plot" currently which reports one p-value. Thanks very much. [[alternative HTML version deleted]]
