Hello: I would like to superimpose vector polygons (state outlines) from a Shape file on top of a satellite image, imported into a SpatialGridDataFrame from GEOTIFF via gdal_translate and readGDAL. When I plot polygon and point shape files in R, into SpatialPointDataFrame and SpatialPolygonDataFrame, the two feature sets line up geographically, so it seems logical that a SpatialGridDataFrame

Hi, I am doing a very informal presentation for my office about R capabilities to deal with and analyze spatial data, display data and maps, and connections with GIS. I've used in my presentation info from the CRAN, the spatial Task view, and the more striking graphics examples from http://addictedtor.free.fr/graphiques/thumbs.php and NCEAS

It appears that "break" will break from the outermost enclosing loop not the innermost loop. Is it a bug or language feature? Tim -- Timothy H.

Hi there, this is my first post to the list. I'm a newcomer to the linux world. I started using it on a regular basis on May and I must say I'm quite comfortable with it, even if I have to re-learn a lot of things. But this is not a problem, I will improve my knowledge with time. My main problem now is that I bought myself a new computer (described at the end of this e-mail) and I was

Is there a way to estimate a nominal response model? To be more specific let's say I want to calibrate: \pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m e^{\xi_{h}+\lambda_{h}\theta_j}} Where $\theta_j$ is a the dependent variable and I need to estimate $\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.

Hello R-users, is there a speed gain in submitting R code in batch mode as opposed to the normal interactive. I searched the R website and the archives, and only found a reference R-data.html that "to read in very large objects it may be preferable to use the dumpfile as a batch script rather than source". Is this true for any R code on both Windows and Linux systems, and how much speed

hi R-users: I have some data related with geographical information. I wonder how to plot some data (in contour,shaded or scatter) on a map. Could anyone tell me which package or reference or examples I can learn ? thank you . -- TANG Jie Email: totangjie@gmail.com [[alternative HTML version deleted]]

Dear R users, I have a city map in shape file (polygon). I also have some points that I hope to plot them to the city map. The only information I have about those points are their relative longitude and latitude to the city center by miles. Is there a way that R can help me to do this? Thanks.

Hallo, I am a newbie to R and desperatley seeking some material about fractal geometry. I found the great library on wavelet analysis of images and I'm now also keen on finding a similar package for calculating fractal parameters for given images. Does anybody know something about such a package? Every hint is greatly appreciated!! I searched already the database, but did not find anything

Greetings, I cvsup'd and rebuilt a FreeBSD 4.8 system last Friday after receiving the realpath security advisory. The machine is remote and the NIC uses the rl driver. After booting the machine I had no network connectivity. The person at the remote site says the boot was normal and he could see that the NIC was properly configured but he could not ping it and I could not login. We booted

I have a procedure that goes sorts out some numbers based on specidifed criteria and for some reason the list contains double values in some of the rows such as: TAZs <- [[84]] [1] 638 [[85]] [1] 643 [[86]] [1] 644 732 [[87]] [1] 651 801 i would like to check list TAZs for double values and remove any if present. I have tried if (length(TAZDs==2)) rm(TAZDs[2]) but no luck. I cant

There is a Fedora Activity Day (https://fedoraproject.org/wiki/FAD_Documentation_2016 ) centered around documentation, where I'm going to see what can be done about the state of centos documentation from upstream sources. Most of the tooling for documentation for these two groups is centered around git. For the most part, our documentation currently lives in the wiki, and has a fairly high

Hi, We are working on a project on forecast modeling and would like to know if there are any examples on how to READ/WRITE to a database (e.g. PostgreSQL) using R-Project. I do have a sample R Script which takes input as files from a directory and writes back output files to a directory. I would like to convert this script to read from a database and write back the output to a database.

Hi, When a single column is subscripted from a data frame it doesn't inherit the row names of the data frame. I find it surprising given the extent to which R tries to carry names across computations. Is there a good reason for this? Here is what I mean in details: > y <- data.frame(a=c(1,2), b=c(1,2), row.names=c("x","y")) y <- data.frame(a=c(1,2), b=c(1,2),
