Hi, I'm trying to use transform my mercator locations into utm but I'm doing something wrong because only x is transformed ... see > xy.sp SpatialPoints: loni lati [1,] -8.85 38.16 [2,] -9.19 37.99 [3,] -9.11 37.97 [4,] -9.06 38.15 [5,] -9.03 37.87 [6,] -9.14 37.81 [7,] -9.09 37.70 [8,] -8.95 37.45 [9,] -9.17 37.37 [10,] -9.00 37.34 Coordinate Reference

Given a data frame consisting of a pointID and 12 pairs of (lat, long) variables, with names latA, longA, latB, longB, ... latL, longL, I want to reshape it into a data frame with the structure point source lat long 1 A ... ... 1 B ... ... I've looked at reshape and plyr, but can't figure out how to do this. Details of my data frame are below

Hi guys, I need your help. I would like to select a subset from a dataset. This is the dimension of the dataset. > dim(data1) [1] 72 36 1916 so, it's like.. there are 1916 of 72 * 36 matrix. ==> looks like 72 * ( 36*1916 ) ** *1)* And I would like to select the first 72*36 matrix. This is how I did: > two=data1[,1:36] Error in data1[, 1:36] : incorrect number of dimensions

Hola a todos. Soy nuevo en R, estoy aprendiendo con tutoriales y lo hago sin un fin comercial y/o laboral. Necesito ayuda para mostrar un mapa y sobre ese mapa poner un punto dado por una coordenada. con esto consigo mostrar el mapa. library(raster) arg<-getData('GADM', country='ARG', level=0) plot(arg) En ese mapa quiero mostrar un punto que está en el sistema de

Hi, I'm running some databases's software on a CentOS 4.5 server and I'd like to know if there are any audit software in CentOS4.5 CDs packages?.....I need some software to audit all the files on the server, I mean, if some one delete a file, or change some permissions on any filesystems, if someone copy files to my server and some of this stuff... take in mind I'm not lookign for

Hi, i hope that''s the correct place for this question. I must update two input text from autocomplete. The list is, for exemple: <ul> <li> <span class="comune_name">pippo</span> <span class="lat" style="display:none">1.2</span> <span class="long" style="display:none">3.0</span>

Hi lily, You could also create "blackcells" as a dataframe (which is itself a type of list). I used a list as I thought it would be a more general solution if there were different numbers of values for different grid cells. The use of 1 for the comparison was due to the grid increments being 1. If you had larger or smaller grid increments, you would use the grid increment size for the

Hi lily, There are one or two assumptions to be made here. First is that the latitude and longitude values of the "black" cells are equally spaced as in your illustration. Second, that all latitude and longitude values for the "red" cells fall at the corners of four "black" cells. You can get the four "black" cells by finding the lat/lon values that are

Hi R users, I have a question about data processing. I have such a dataset, while each black grid cell has a few attributes and the corresponding attribute values. The latitude and longitude of the center of each grid cell are given also. Then I want to average the attribute values from four adjacent grid cells to get the average value for the center of each red grid cell. Thus, there are the
