Hi R users, I am trying to omit rows of data based on partial matches an example of my data (seal_dist) is below: A quick break down of my coding and why I need to answer this - I am dealing with a colony of seals where for example A1 is a female with pup and A1.1 is that female's pup, the important part of the data here is DIST which tells the distance between one seal (ID) and another

Dear R Group: I have little experience using R and even less experience with control flow type questions. See the following code: a1 = c(0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0) for(i in 1:1){ sx <- paste("a",i,sep="") s <- eval(parse(text = paste("a",i,sep=""))) {g = numeric(length(s)) k =

I have the following: Time A1 A1 B1 B1 C1 C2 x y x y x y 0 5 6 6 7 7 9 1 3 4 4 3 9 9 2 5 2 6 4 7 4 I want to change it to the following: 0 1 2 x y x y x y A1 5 6 3 4 5 2 B1

Is anyone using these softwares in Wine ? Does it work ? Pasquale

Hi, I have been thinking about your questions and comments. And I think I have the answers. :D > the way you draw the polygons has the consequence that if the larger one > is drawn after the smaller one, > the color of the smaller one is "overwritten" > and therefore the map is really wrong in the relevant area. > so this needs fixing.

Dear Barry, Thanks for your stimulating reply. As you see I have send a CC of this reply to the R mailing list. The R mailing list will be the best place to send your queries. You can subscribe here: http://www.r-project.org/mail.html I would think there is an interest in the provision of landscape indices analysis methods in R. There are several packages for landscape indices analysis

What tools and documentation exist for producing maps and working with polygon and polylist objects in R beyond the following: * Packages maps, mapproj, maptools, and mapdata. * Becker and Wilks (1993, 1995), listed as references in the documentation on the "map" function. Thanks, Spencer Graves

Dear Sirs: I am not yet a user of R. My background includes the use of (Turbo) Pascal for scientific analysis of underwater acoustics problems (e.g. sound ray tracing and array gain in directional noise fields.) I have become interested in the following type of problem: (1) select , say, 1000 random locations within the continental United States; (2) characterize (statistically) the

Dear all, I am interested in plotting maps visualizing spatial statistics in an aggregated fashion, according to administrative boundaries. Partially, I want to visualize some spatial data for administrative units (autonomous republics, oblasts, krays) of the Russian Federation on a geographical map. I have found the maps package (and related) and would like to use this package e.g. in a kind

If _you_ were asked to give a 40 minute dog and pony show about R for a group of scientists ranging from physicists to geographers what would you put in? These people want to know what R can do. I'm thinking about something like: A. Overview B. data structures C. arithmetic and manipulation D. reading data E. linear models using glm F. graphics G. programming H. other tricks like rpart or

Hello Thomas, I am writting to you because I have some questions about R-(D)COM. The first one is whether it can compiled using the MINGW C compiler, that is recomended by B. Ripley to compile R under Windows. The other questions are: - How can I open/close connections directly from C/C++? - Do you know about a free Visual Basic compiler? The final purpose of using R-(D)COM is to create a

The main limitation of the shapefiles package that I put together is that it does not create shapefiles from R objects - rather it only writes shapefiles that have been read into R and manipulated within the constraints of the existing file structure. By this I mean that for example you can change the coordinates of points and write them back out. Or you can add a bunch of blank columns in the

Salutations: I have been trying to translate a S-PLUS/ArcInfo (GIS software) application that I wrote on a SGI (IRIX) platform to public domain R and GrassGIS on a Linux platform. I am almost on the verge of abandoning it as I find R to be rather unstable, slow and frustrating. I enclose a section of my code for R experts to examine hoping that they'll point out that all the above three are

Hello: I''m a little confused as to the >0.20 brb syntax as it relates to autostart and repeat. In short, I''d like to know the easiest way to automatically start a worker and have it repeat every xx minutes. This was easy in the previous version because you would simply do : ''repeat.every 20.minutes'' or similar in the worker. I''m sure

So disregard this question. I followed Mason Hale''s suggestion that I pass in some worker_args and all is well in the scheduler.yml file.

Is there a way in TCL/TK to trigger an event multiple times while a button is held down? I'd like to have an rgl scene continuously rotate until the button is released. Duncan Murdoch

I have verified this on two machines, but it would be helpful if others out there can reproduce it too. Also, I do not know if it is Xorg or the FreeBSD keyboard drivers, since I see no way to reproduce on the console (i.e. turn off repeat). In an xterm, type: "xset r off". Then try some multiple-key combinations (i.e. keep holding first key(s) when you type the next one): po (o does

Hello, I would like to use a permanova to analyze my repeated measures, multivariate data set using the package vegan (adonis function). I have several explanatory variables and many clinical biochemistry/hematological response variables (all continuous, non-normally distributed). My explanatory variables are: ID - 29 levels - individual subjects Treatment - 2 levels Sex - 2 levels Time -

Hello I posted a very similar question last week, but the responses I received indicated that my post was unclear....
