Hello all, A question for plotting of intamap results : Is it possible, and in so, how, to specify the cutoff points for changing colors of plots ? Using the example : data(meuse) meuse$value = log(meuse$zinc) data(meuse.grid) coordinates(meuse) = ~x+y coordinates(meuse.grid) = ~x+y object = interpolate(meuse,meuse.grid,outputWhat = list(mea...

...ge after installing. I have read about the use of "Suggest", "Enhances" etc in "Writing R Extensions", but could not figure out the right way to do this. I am sure there is something I am missing here. If anyone wants to check possible solutions, package A is "intamap", available from CRAN, whereas B is "rtop", available from Rforge: **|install.packages("rtop", repos="http://R-Forge.R-project.org")|** Thanks, Jon -- Jon Olav Skøien Joint Research Centre - European Commission Institute for Environment and Sustainability (IE...

Suppose that I'm working on Hadley's diamond dataset and I want to review the relationship between price, colour and carat. I might run the following: library(ggplot2) #plot scatter and add some hex binning q<-qplot(carat,price,data=diamonds, geom=c("hex"), main="Variability of Diamond Prices by Carat and Colour") #facet to get one scatter for

Dear R List, I want to download kinship_1.2_S.tar.gz in http://mayoresearch.mayo.edu/mayo/research/biostat/splusfunctions.cfm to R. Once save this file to C:\, how I could load into R? I am working in Windows XP. Usually what I do is, I go to "packages" and then "install packages from local zip files". This procedure fails for .tar.gz files. Can someone help here please....

Dear all, I'm working with satellite images in R and plotting them via the code below. I was wondering whether coordinates (spatial["x"], spatial["y"]) are used as centre coordinates of the pixels in the GRID? In this script; spatial["x"] & spatial["y"] are the centre coordinates of the satellite image pixels. I'm asking this because some

Dear R-users, I am trying to make a plot with ggplot-geom_tile(), but cannot remove some unwanted (white) lines through my plot. Below a reproducible example: ##### library(ggplot2) tot=as.data.frame(rep(seq(-50,50,5),each=21)) names(tot)="precip" temp=rep(seq(-5,5,0.5),21) tot$temp=temp disc=array(dim=c(21,21)) for(i in 1:21){ for(y in 1:21){ temp<-

Hi Listers, Is it possible to produce an ordination plot in 2d, where bubbles represent the location of sites (this part is easy enough) and the size of the bubbles is proportional to the sites location in 3d space (I am stuck on this option). So sites that are very near the 2d plane of the xy axes would be larger while sites that are actually further away in 3 d space would be proportionally

hi I've used R for many years on windows machines, but have now acquired an Asus eee 1000 linux machine. In order to get the best out of the machine, I used the 'pimpmyeee.sh' script, to get the full KDE desktop. The version of Linux is Xandros, which I believe is a close relative of Debian, but sadly I have only a nodding acquaintance with Linux at present. Naturally I want to

I am not new to R, but I am new to .grib files. I am downloading some climate data and I would like to analyze it in R. R has a nice netcdf package, but I don?t see any package available to deal specifically with grib files. I see a few posts from other people using grib files in R. However, I was unclear if they used grib files in a different software program and then imported the data

Hello everyone, I was asked to repost this again, sorry for any inconvenience. I'm looking replacement for ddply function from plyr package. Function allows to apply function by category stored in any column/columns. Regular loops or lapplys slow down greatly because my unique combination count exceeds 9000. Is there any available solution which allow me to apply function by category?

Hello I'm working with a large hydrological data set stored in a netCDF format. The file stores x and y coordinates in the UTM projected coordinate system, yet when I use image to graphically display the z variable, the image is distorted in the sense that it does not plot the map in the correct spatial organization. I'm wondering if I need to define the projection of the netCDF file

Dear Lister, I understand I can put '#' to put comment line by line. But is there a way to put comment with multiple lines without having to put '#' on the every line? Thanks.

Hello 'R' Users, I have a monthly mean CO2 necdf data file defined on 1x1 lat by lon coordinate. I want to sub-sample this variable CO2 on the coordinates of another ASCII data file.
