Thanks a lot for your time, Cheers, Navin

Dear R Users, I have a data frame of the nature: > head(aggregate_1986) Latitude Mean Annual Simulated Runoff per 1? Latitudinal Band 1 -55 574.09287 2 -54 247.23078 3 -53 103.40756 4 -52 86.99991 5 -51...

I am trying to plot positions on a grid where the x and y axis equate to longitudinal and latitudinal co-prdinates respectively. As these co-ordinates are southings and westings, i need the origin of my graph to contain the two highest values of each co0ordinate, with the values decreasing in both respects along both axes - I cannot seem to find any function within r to allow me to do this. Also,...

Dear R-helpers, I get GPS readings with bug counts (bugs meaning insects in this case) made along rows in crop fields and use these to make maps of bug distribution. The GPS readings are not quite accurate enough for my purpose, so since I know what row each reading is made in, I adjust the latitudinal coordinate using: grd<-lm(lat~lon+Row,data) data$lat<-predict(grd[,c("lon","Row")]) which adjusts the latitude pretty well when the rows run East-West, but not at all when the rows run North-South, and it doesn't adjust the longitude at all. Is there a bette...

...ased on the Sim_1986 values between where Latitude 85, 84, 83, 82. The maximum latitude in the dataset as a whole is 83.75 and the minimum is -55.75. Is it possible to also output corresponding latitude values for each 'grouped mean', so that I can easily associate each mean value with its latitudinal band? Many thanks for any help offered, Steve _________________________________________________________________ [[elided Hotmail spam]]

Hi, QUESTION TOPIC #1 I have some data I want to plot on a map. But what I have are home addresses: street, City, State, complete postal code--i.e 95377-1234. Is there a way to plot this data or do I need latitudinal and longitude coordinates? If so how do I convert them? Is there a package that will do the conversion in R? QUESTION TOPIC #2 I was trying to experiment with this code that I found at the site below but got a message that indicated that the "map" function is not found. So I tried instal...

...values are latitudes (from 89.5(N) to -89.5(S)). What I want to do is convert this 1 degree dataset to a finer resolution of 0.5 degrees, thereby quadrupling the number of cells within the frame (i.e. convert to 720 x 360 grid). I wish to have longitudinal values ranging from -179.75 to 179.75 and latitudinal values from 89.75 to -89.75. I selected the 'interp.surface' function in the 'fields' package to do this as it provides bilinear interpolation from one grid to another. I have written the following code to try and carry out my interpolation... > library(fields) > x.mat <-...

Hi, I've extracted netcdf data in R, and am trying to output it in a matrix format. I can make the matrix, and I have the data, but I can't get the matrix to include the data... I'm not very experienced at using R, so please forgive the crudeness of these codes... # For the matrix wind_dir_data<-matrix( NA, 17, 365 , byrow = FALSE ) wind_speed_data<-matrix( NA, 17, 365,

Hello This is Elaine. I am using package lattice to generate boxplots. Using Richard's code, the display was almost perfect except the outlier shape. Based on the following code, the outliers are vertical lines. However, I want the outliers to be empty circles. Please kindly help how to modify the code to change the outlier shapes. Thank you. code package (lattice) dataN <-
