search for: long2

...ke 10.1 release: R 2.0.0 editor: GNU Emacs 21.3.2 front-end: ESS 5.2.3 --------------------------------- Colleagues Is there a function to calculate distances between adjacent latitude/ longitude pairs in a matrix? It is basically a spatial diff() function that I have in mind. Data: long1, lat1 long2, lat2 long3, lat3 looking for: diff(data$long, data$lat) function Result long1, lat1 long2, lat2, distance = long/lat2 - long/lat1 long3, lat3, distance = long/lat3 - long/lat2 I've probably missed it but a search of the maillist archives and quick scan of the packages (map*) did not solve...

I am wondering if there is a function which will do a join between 2 data.frames by minimum distance, as it is done in ArcGIS for example. For people who are not familiar with ArcGIS here it is an explanation: Suppose you have a data.frame with x, y, coordinates called track, and a second data frame with different x, y coordinates and some other attributes called classif. The track data.frame has

Dear all, I have used 'read.table' to create a data frame of 720 columns and 360 rows (and assigned this to 'Jan'). The row and column names are numeric: > columnnames <- sprintf("%.2f", seq(from = -179.75, to = 179.75, length = 720)). > rnames <- sprintf("%.2f", seq(from = -89.75, to = 89.75, length = 360)) > colnames(Jan) <- columnnames

All - I have a large data frame that looks like ID p1 p2 p3...p20 Lat1 Lat2 Lat3...Lat20 Long1 Long2 Long3...Long20 1 0 0 1 0 NA NA 29.xx NA NA NA -89.xx NA 2 1 0 0 1 27.xx NA NA 29.00 -88.00 NA NA -89.xx 3 0 0 0 0 NA NA NA NA NA...

Deemed colleagues I would appreciate your help with a sentence to calculate the linear distance between 2 geographical points (coordinates in UTM).

i have a large longitudinal data set. The number of observations for each subject is not the same across the sample. The largest number of a subject is 5 and the smallest number is 1. now i want to make each subject to have the same number of observations by filling zero, e.g., my original sample is id x 001 10 001 30 001 20 002 10 002 20 002 40 002 80 002 70 003 20 003 40 004 ...... now i wish

Apologies for troubling the list, but it is a test that needs to be carried out. I am resending the message that I sent earlier on behalf of Paul Miller, but with a certain word used in the variables names of the SAS code changed to a different word. With thanks for your tolerance ... Ted. [*** PLEASE NOTE: I am sending this message on behalf of Paul Miller: Paul Miller <pjmiller_57 at
