Hello, I need to chenge axes orirentation in triangle plot. (function triangle.plot in ade4 package) I want to plot elasticities of some species in demographic triangle, where axes values commnly increace "clockwise". If some better imangination is needed, see http://www.open.ac.uk/science/biosci/personalpages/j.silvertown/pdfs/Silvertown%20et%20al.%201993.pdf I am sorry if I just

Hello, I want do get the point to point distance matrix. Suppose, I have a data frame where the first column is X and second column is Y coordinate of points. I define a function dst(x1,y1,x2,y2) to claculate distance between two points. But I don't know how to tell R to calculate dst for every two points and create a matrix of these distances. Can you give me a little guidance, please? I am

A quick question. I am trying to understand how I could move the installed packages in my R 2.3 version to the newly installed R 2.5 version, without having to install all the packages again. I copied the files under the old library subdirectory to the new library subdirectory. But still the newer version is not recognizing the packages that were copied over. Thanks.

Dear useRs and wizaRds, I am currently developing a set of functions using S4 classes. On the way I encountered the problem exemplified with the code below. For some reason the 'validity' method does not seem to work, i.e. does not check for errors in the specification of the slots of the defined class. Any hints? My understanding of the whole S4 system was that validity checks are made

Hello dear useRs and wizaRds, I encountered the following problem using the hist() method for the 'times' classes from package 'chron'. You should be able to recreate it using the code: library(chron) # pasted from chron help file (?chron) dts <- dates(c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92")) class(dts)

Hello everyone, I encountered the following confusing behavior of 'deparse' and 'substitute' while programming with S4 classes (see example below). It seems like the presence of '...' argument in the definition of the generic generates the problem. I have no clue why, can anyone explain that to me? Are there any "workarounds"? Thanks a lot for your time!

I have the same question that Eusebio had: Is there a function similar to "sink" that redirect also R code to a file that is: sink("R001") x <- c(2,-6,-4,8,5,4,1,3,4,-9,0,1) A <- matrix(x, ncol=3) A A.prima <- t(A) A.prima dim(A) dim(A.prima) sink() create a file "R001" with contents: ------------------------------------------ [,1] [,2] [,3] [1,]

Dear R helpers, I have a graph as following; I would like to highlight the overlapping area between the two curves. Do you know how to do this? Thank you in advance for your help.

Hello, R experts, I have a list called dataHP which has 30 elements (m1, m2, ..., m30). Each element is a 7x6 matrix holding yield data from two factors experimental design, with treatment in column, position in row. For instance, the element 20 is: dataHP[[20]] col1 col2 col3 trt1 trt2 trt3 [1,] 22.0 20.3 29.7 63.3 78.5 76.4 [2,]

Hi all, I'd like fit this function: G(t)=A*1/(1+t/B)*1/sqrt(1+t/C) where A, B and C are fitting constants that one like search. I have got a fcs<-(t,G(t)) value table in a data frame. Any one can help me? Tahnks Horacio.

Hi All, I have a very simple problem. I have several files in a same directory. I would like to send for an object only the files that finish in ".sens.". I execute the command below, files <- dir(pattern="*.sens") but it includes all of the files that have "sens", independent of they be in the end or in the middle of the name of the file. How could I solve

Hi, Is there a smart way in the R graphs to create a line that is broken in intervals based on the indicator given below. following is a small test graph Location,indicator,otherinfo 1.2,1,2.2 2.5,1,2.5 3.7,1,2.3 20.1,2,4.3 22.5,2,5.2 25.0,2,3.4 27.3,2,2.2 35.1,3,3.4 37.0,3,7.2 38.0,3,6.1 40.1,3,5.4 52.9,3,3.3 Right now in the plot the line is continuous, but I would like to have it broken

Hi, I ran into the following peculiarity involving S4 method dispatch and namespaces. I develop a package which have a namespace and which depends on 'pixmap' package, which itself does not have a namespace. Now, in my package I have a class which has a slot for objects from class "pixmap" and I want to have a "plot" method for this new class. Not to clutter the

Hello to all. My name is Michal Bojanowski, I'm a Sociology student at Unversity of Warsaw. Recently I've started to learn R when I've found myself frustrated because of inflexibility of SPSS and other "user-friendly" statistical software. As I said, I'm new here, so my question is very simple: I wanted to use a large data set stored in SPSS-format file. I used the

Dear R Help, I have noticed some inconsistent behaviour of add1 and drop1 with a weighted linear model, which affects the interpretation of the results. I have these data to fit with a linear model, I want to weight them by the relative size of the geographical areas they represent. _________________________________________________________________________________________ > example
