coordinates

问题 I get the following error from the gps: Fatal Exception: java.lang.NumberFormatException Invalid double: "-٣٣٫٩٣٨٧٤" Now this is from a error that I got from a user via Fabric. It looks like arabic so I'm guessing it only happens if you have the language set to that, or your sim card? Is it possible to force the gps to send characters in the 0-9 range? Or can I somehow fix this? 回答1: Try this: String number = arabicToDecimal("۴۲"); // number = 42; private static final String arabic = "\u06f0

问题 I have a ggplot object. I would like to add some text with annotate() , and I would like to specify the coordinates of the text in npc units. Is this possible? This minimal example demonstrates how text is ordinarily positioned with annotate() : library(ggplot2) p <- ggplot(mtcars, aes(mpg, wt)) + geom_point() p + annotate("text", x = 30, y = 4.5, label = "hello") I would like to achieve the same effect, but instead of specifying x and y in native coordinates, I would like to specify them

问题 When programmatically adding an array of GPS Coordinates to a Bing Map, I want to set the Zoom level to the optimal - to show every pushpin/location, but "just barely." I imagine a way to do this would be to identify the furthest points in the cardinal directions found within the array of coordinates, and then calculate how many miles you need to display both east-to-west and north-to-south. For example, let's say the furthest north and furthest south locations are determined to be forty

问题 I'd like to get accelerometers on Android and have them on the earth coordinate system, just like on this topic Acceleration from device's coordinate system into absolute coordinate system or here Transforming accelerometer's data from device's coordinates to real world coordinates but these solutions don't work for me. I'm working on Processing. The project is simply to track the phones accelerations in space, no matter how it is (standing, on the side...). I'm new to Android too. I'd

问题 I've been looking for a solution to convert cartesian coordinates (lat, long) that I have to polar coordinates in order to facilitate a simulation that I want to run, but I haven't found any questions or answers here for doing this in R. There are a number of options, including the built in function cart2pol in Matlab, but all of my data are in R and I'd like to continue getting comfortable working in this framework. Question: I have lat/long coordinates from tagging data, and I want to
