Dear All, I have a file data.txt as follows: Name_1,A,B,C Name_2,E,F Name_3,I,J,I,K,L,M I will read this with: my_data<- read.csv("data.txt",header=FALSE,col.names=paste0("V", seq(1:10)),fill=TRUE) Then the file will have 10 columns. I am assuming that each row in data.txt will have at the max 10 entries. Note: Here each row will have a different number of columns in

# Let's say I have 5 objects, object_1, object_2, etc. for (i in 1:5) { assign(paste("object_",i, sep=""), i+500) } # Now, for whatever reason, I don't know the names of the objects I've created, but I want to operate on them. list<-ls(pattern="^obj") #Is get best? for (l in list) { cat("\n", l, "is", get(l), sep="

Hi, I am looking for a way to find out the version information of installed R packages. ex: >library(affy) >SOME_COMMAND_FOR_VERSION(affy) I know I can do either getRversion() or R.Version() could give me the version of R. I assume there must be a way for me to get version information for the add-on paclages,right? Thanks! Yupu

Hola He hecho el típico mapa con gadm y spplot: library(sp) ES <- local(get(load(url("http://biogeo.ucdavis.edu/data/gadm2/R/ESP_adm2.RData ")))) acerco las canarias: A <- which(ES en data$NAME_1 == "Islas Canarias") L <- length(ES en polygons[[A]]@Polygons) L <- length(ES en polygons[[A]]@Polygons) for (i in 1:L){ ES en polygons[[A]]@Polygons[[i]]@coords

Hola, Yo lo resuelvo usando grid.rect. Tienes una posible solución aquí: https://github.com/oscarperpinan/spacetime-vis/blob/master/choropleth.R#L216 (que es una versión actualizada de este artículo https://procomun.wordpress.com/2012/02/18/maps_with_r_1/) Saludos.

I would like to select polygons from an existing spatial polygon data set interactively in a shiny leaflet map. The process is straightforward in leaflet/ mapedit, however I need to include the procedure in a shiny app map interface. I cannot work out how to incorporate the selectMap() in the shiny app. An error is returned: Here is some toy code showing the code in using leaflet locally:

I am having trouble getting data labels to display over the provinces in a GADM map of Canada. Specifically, I need the variable "Number" from the data set "by_province", grouped by "region", to appear on the corresponding regions of the map. The data set "by_province" looks like this: long lat order hole piece region

I have csv data that extend beyond the area I want for an existing map. I want using the boundaries of the polygon shape file as a cookie cutter so that I can overlay the csv data on map without including anything outside the map boundaries and create a dbf file or shapefile of the clipped data .  The reproducible example: ############################################### library(RColorBrewer)

Dear Rs: Hi, I am trying to read a big text file (nrows=243440, ncols=144). It seems the computational time of all the read methods (scan,readtable,read.delim) is not linear to the number of rows I want to read in: things became really slow once I tried to read in 100000 lines compare to 10000 lines). If I am reading the profiling result right, I guess scan wouldn't help either. My

Hello! I have 2 maps - both created in ssplot and both identical in terms of outline. Is there any way to superimpose Map1 (which has black borders between Canadian provinces) onto Map2 (which is also a map of Canada)? Thanks a lot for your hints! Dimitri ### A. Reading in Canada data at the province and then at the county level: library(raster) getData('ISO3') # Canada's code is

Hi all, From the web, I can find a table scheme of sipusers for ARA using. However, I can't find any meaning of each field, especially for the field regserver which is new in the table. Can any tell me more detail about the usage of each field? CREATE TABLE `sip_buddies` ( `id` int(11) NOT NULL auto_increment, `name` varchar(80) NOT NULL default '', `host` varchar(31) NOT NULL

Dear all, in GADM map there are three levels (nation, province and precinct) for each country of the world but for all of them you are never able to plot only one part of a chosen country. To be sure, I am trying to plot only one region of “Italy” and colour the different precincts in it. So far I am able to colour only the part of my interest but the programme still plot the whole country. Is

ok so my table looks like this... REATE TABLE `sip` ( `id` int(11) NOT NULL auto_increment, `name` varchar(80) NOT NULL default '', `accountcode` varchar(20) default NULL, `amaflags` varchar(7) default NULL, `callgroup` varchar(10) default NULL, `callerid` varchar(80) default NULL, `canreinvite` char(3) default 'yes', `context` varchar(80) default NULL, `defaultip`

Guys, I'm having a hellava time getting realtime to work, focused on sipusers right now, followed the wiki and other examples but still no luck. Using mysql on a seperate server, asterisk actually sees the database and can poll the table "realtime load sipusers" at the cli but asterisk realtime engine is no pulling the user info. I'm using 1.2.4 stable and have the database

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts

I'm having trouble with the Realtime setup. I've followed the instructions on voip-info using odbc but I get this message during asterisk boot: Parsing '/etc/asterisk/sip.conf': Not found (No such file or directory) Dec 14 16:11:37 NOTICE[8868]: chan_sip.c:8462 reload_config: Unable to load config sip.conf, SIP disabled == Registered channel type 'SIP' (Session

After much head-scratching I finally figured out how to get a custom icon for the Main Menu on the panel. For the benefit of anyone else who wants a custom icon: yum install gconf-editor Run gconf-editor and go to apps - panel - objects The main menu is one of the "object_0", "object_1" items. Just go through them until you find the one that is the Main Menu. Put a

maybe a dumb question but what do we have here??? sip-friends.sql # # Table structure for table `sipfriends` # CREATE TABLE `sipfriends` ( `name` varchar(40) NOT NULL default '', `secret` varchar(40) NOT NULL default '', `context` varchar(40) NOT NULL default '', `username` varchar(40) default '', `ipaddr` varchar(20) NOT NULL default '',

Not being an asterisk expert, but having been around the block once or twice when it comes to data and the like, I have made some observations based on the examples given on voip-info.org Sip configs. it appears there is an adjustment to be made in the sip_buddies example table: >>> name Although set to 30 characters, I don't see where it is limited in the text file. In theory,

Hi all! So far I've always used plaintext passwords for SIP, but now I've decided to use MD5 encryption. For each client I edited its section as follows, then: auth=md5 md5secret=hashed_passwd ;secret=plaintext_passwd where hashed_passwd is the output of echo -n "user:realm:plaintext_passwd" | md5sum When the first SIP clients registers with Asterisk after a "sip
