Hello all, I changed the subject line of the e-mail, because the question I''m posing now is different than the first one. I hope that this is proper etiquette. However, the original chain is included below. I've incorporated bits of both Ethan and Brian's code into the script below, but there's one aspect I can't get my head around. I'm totally new to programming

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

i have squid running on DMZ zone and my network using ProxyARP on eth1 and eth2 mylinuxbox slackware 9.2 my network can access to internet normal, but can''t redirect to squid server from firewall. sometimes my network can connect to squid and sometimes bypass this squid server. i dont know what going on. now.. my network bypass redirect to squid server. my config file follow document

Hi all, ?I'm trying to iterate in a SpatialPolygonDataFrame thatcontains 110 features. I tried to use the following code? iterate.spdf =function(x){ for (i in 1:nrow(x)){ p = x[i, ]} return(p)} but with no success as it returns with aSpatialPolygonDataFrame that contains onlyone feature. The code seems to overwrite the polygons to end up with only onefeature. ?Any suggestions?Ashraf, cheers

Hello, I have a function with a long list of parameters (of different types, numeric and string) myFunc <-function(p1, p2, p3, p4, p5...etc) { do.something(p1,p2,....) } I want to loop over this to provide a different set of parameters to the list every time. for (ii in 1:N) { myFunc(p1(ii), p2(ii),....etc) } I would like to simplify the notation and use some kind of structure, maybe

Gracias Beatriz, efectivamente, lo que indicas en tu ejemplo es lo que obtengo al final de mi proceso. En todo caso pruebo tu opción con mis datos, si es como imagino seguro que es más rápida de montar y más elegante que tratar el resultado de un sink() (recuerdo que en su momento lo intenté con fotify pero no supe bien como atacarlo, no conocía el enlace que me mandas, por tanto lo pruebo de

Hi R-experts! Every once in a while I need to convert a factor to a vector of numeric values. as.numeric(myfactor) of course returns a nice numeric vector of the indexes of the levels which is usually not what I had in mind: > v <- c(25, 3.78, 16.5, 37, 109) > f <- factor(v) > f [1] 25 3.78 16.5 37 109 Levels: 3.78 16.5 25 37 109 > as.numeric(f) [1] 3 1 2 4 5 > What I

Dear Colleagues, I used this code to scrape data from the URL conatined within.

Hello all This is my first posting for some years. I am back using R again and must say I do like the language (regarding scripting, I also use matlab, perl, and bash). My question involves plotting a Pareto frontier in three dimensions. This is strictly a exercise in visualization, I make no attempt to extract the Pareto set (aka dominating subset) first. EXAMPLE PLOTS For some example

We are using Shorewall 2.0.8 with SuSE 9.1 and have built a bridging firewall primarily to defend against syn flood and smurf DoS attacks. We are a small ISP using Cisco routers for a total of 5-6 subnets. Since bridges are based on use of MAC addresses, if we could use one bridging firewall system instead of 5-6 ... is this possible? practical? (Other than introducing a single point of failure

Dear subscribers, I am looking for a function which would allow me to model the dependent variable as the number of successes in a series of Bernoulli trials. My data looks like this ID TRIALS SUCCESSESS INDEP1 INDEP2 INDEP3 1 4444 0 0.273 0.055 0.156 2 98170 74 0.123 0.456 0.789 3 145486 30 0.124

Oscar, al final no he podido esperar hasta mañana Con: library(maptools)library(sp) poligonos <- readShapeLines("C:\\...\\DATOS\\MUNICIPIO.shp") sink("C:\\ ... \\DATOS\\MUNICIPIO.csv") coordinates(poligonos) Consigo un fichero con la suficiente estructura para tratarlo fácilmente y de una tacada montar la tabla .csv tal y como he indicado en un correo anterior Necesito el

Dear R-helpers, I have lat/lon coordinates of regularly spaced grid points, about 4Km apart, covering the entire US continental region. I would like to mask this rectangular grid in order to extract all and only the grid points within a specific region. Today I want to extract Montana, say, from this grid, and I am hoping to somehow use the returned value of the function

Hello all, I am attempting to join samba4 to my current domain which is controlled by a Windows 2012 Active Directory Server. When following the instructions on the official WIKI: http://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC I am able to do a kinit administrator, which then gives me a ticket which I can see via klist. The problem is that once I run the command: #

I?m working on an OS project from github. There are two parts: Dovecot plugin - https://github.com/st3fan/dovecot-xaps-plugin Daemon written in Go - https://github.com/st3fan/dovecot-xaps-daemon # dovecot --version 2.2.10 Both parts worked fine on CentOS 6 but I recently rebuilt them both for CentOS 7 and have run into some errors. The plugin sends a notification over a socket to

Hi all, I've been using the scatterplot3d function (from the scatterplot3d library) to create 3D plots. I was wondering whether there is anyway to group the points according to a particular group variable. For example I used the plot function as plot( factor( <GROUPINGVAR> ) , <PLOTVARS> ) to organise the results in a according to the grouping variable. I was wondering

Hi all! The following files emits warnings when compiled with gcc 4.0: al175.c bcmxcp_ser.c belkinunv.c cyberpower.c everups.c powercom.c solis.c All warnings seem to be of this variety: everups.c:38: warning: pointer targets in passing argument 2 of 'ser_get_char' differ in signedness I suggest that those who fiddles with those drivers fixes the warnings and verifies that it works
