Dear R-users, Just like other users (as seen from previous posts on the list), I would like to use female and male signs in plots. I found B. Ripley's post about using Unicode characters. However, it doesn't works for me. > text(locator(1),"\u2640") produces the following error: Error: invalid \uxxxx sequence But I can specify other Unicode characters as long I

Dear list readers, Can someone of you explain this behavior. Here's a toy example: Start by constructing a function tmp >fix(tmp) In the default editor enter this one-liner: hist(rnorm(10)) close the editor and run environment on the function. > environment(tmp) <environment: R_GlobalEnv> Open the editor and remove the last parenthesis, this will make the editor choke.

Hi, Can someone of you tell me why these two simple examples works as "expected", plot(c(1,1,2,2)~c(1,2,1,2),col=c(1,2,3,4),pch=c(1,2,3,4)) coplot(c(1,1,2,2)~c(1,2,1,2)|c("A","A","B","B"),col=c(1,2,3,4),pch=c(1,2,3,4 )) but when I try it with xyplot in the lattice package it fails.

Hi, I have problem with saving and later sourcing boot objects. A short familiar example... R : Copyright 2001, The R Development Core Team Version 1.3.1 (2001-08-31) ... > library(boot) > data(city) > ratio <- function(d, w) + sum(d$x * w)/sum(d$u * w) > boot.res<-boot(city, ratio, R=999, stype="w") > dump("boot.res","boot.res.R") > Save

Dear R users, I know that this could easily be solved within a GIS-package, but sometimes it's more convenient to use R. So here's my question anyway... Does anyone of you know about any R-functions/code that calculates the distance between a number points and a polygon or polyline? I have looked thru the different libraries that deals with spatial statistics but haven't found

Hi all, when testing the new improvements in the new 1.7.0-version I stumbled over the following: >eigen(matrix(c(0,.3,2,.9),2,2)) Error in eigen(matrix(c(0,.3,2,.9),2,2)) : LAPACK routine DGEEV gave error code -13 >eigen(matrix(c(0,.3,2,.9),2,2),EISPACK=TRUE) $values [1] 1.3458236 -0.4458236 $vectors [,1] [,2] [1,] -1.1436890 -0.9760443 [2,] -0.7696018

I am making a battery of levelplots and wireframes for several fitted models. I wrote a function that takes the fitted model object as the sole argument and produces these plots. Various strange behavior ensued, but I have identified one very concrete issue (illustrated below): when my figure-drawing function includes the addition of points/lines to trellis plots, some of the

Hi everyone, I want to plot some pattern. For example, I have some coding as below, plot(0:11,type="n") polygon(c(6,8,10), c(7,3,5),bor=6) polygon(c(2,4,6), c(5,3,7),bor=6) polygon(c(6,10,8), c(7,9,11),bor=6) polygon(c(2,6,4), c(9,7,11),bor=6) This coding will give me four triangles, but how to generate more triangles in sequences so that not need to mention the coordinate for each

Dear R-users, I have a plot created with the code below. I tried to put some text to the right of the color key. I worked with grid.text and also viewport(), but couldn't achieve this. I know this should be simple, but I just couldn't figure out how to do it. How does this work? Cheers, Marius library(lattice) library(grid) myvec=1:10 data=data.frame(x=myvec,y=myvec)

Hello, I want to add a single contour line to a levelplot but can't figure out how to do it 'on-the-fly'. When I include the last line in the code below, I get the following error: Error in NextMethod("[") : Argument "subscripts" is missing, with no default Any tips on how to fix this are greatly appreciated!

Hi all, I'm new to the list...pretty new at learning to code in R... Is there a way to relate 2 different arrays in R? Hypothetical example: data1 ID z 1 100 2 250 3 75 4 12 5 89 data2 ID z 1 1 1 1 2 3 4 3 4 5 5 5 etc. Goal is to fill column z in data2 with appropriate z-values from data1 that correspond to a given ID. I'm looking for something akin to a

Using the Hmisc package, I tried to create an xYplot (single panel only) and was confused to find that I could not add anything else to the plot (abline, lines, etc.). Thankfully, [1] points out panel functions. This works as expected for panel.abline, but as soon as I'm using panel.lines (or llines or lpoints) from the "lattice" package (version 0.17-17 with R 2.8.1), it

Dear all, I'm wanting to do a series of comparisons among 4 categorical variables: a <- aggregate(y, list(var1, var2, var3, var4), sum) This gets me a very nice 2-dimensional data frame with one column per variable, BUT, as help for aggregate says, <<empty subsets are removed>>. I don't see in help(aggregate) how I can change this. In contrast, a <- tapply(y,

Dear List members, its me again, fighting with lattice graphics. I am trying to plot a world map, add some points on different locations with different colors and add a legend, but did not succeed yet with the legend. Here is my code: library(fields) # Data for demonstration data_x = c(0,50,60) data_y = c(0,0,0) cols???= c(1,2,3) data(world.dat) #print map all=xyplot(world.dat$y? ~

Hi, I am interested in ggplot2 and I found this lattice code very interesting (http://addictedtor.free.fr/graphiques/graphcode.php?graph=48). Code: library(lattice) lattice.options(default.theme = canonical.theme(color = FALSE)) tmp <- expand.grid(geology = c("Sand","Clay","Silt","Rock"), species = c("ArisDiff",

Hello, I have two short questions concerning a key (legend) in a lattice plot. I have points represented by two different plot characters (crosses and circles) and they are colored from light to dark gray. I would like to have 3 parts in my legend showing the two different plot characters in the first two lines and the last line should consist of a line segment for explaining the

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

Hi, I am trying to create a triangular plot to show the 'composition' of a set of items with three variables (historically the percent sand, silt and clay in soil). So far I have tried the 'soil texture triangle plot' in the package plotrix and the 'ternary or triangular plots' in the package cwhtool (cwhmisc). Both have strengths and weaknesses, but neither has a

Suppose I have three numbers p1, p2, p3 with 0 <= p1,p2,p3 <= 1 and p1+p2+p3=1, and a function f=f(p1,p2,p3) = f(p1,p2,1-p1-p2). How to draw a contour plot of f() on the p1+p2+p3=1 plane, that is, an equilateral triangle? Functions triplot(), triangle.plot(), and ternaryplot() give only scatterplots, AFAICS -- Robin Hankin Uncertainty Analyst National Oceanography Centre,

Dear R Group I was trying to use the triangle.test function in SensoMineR and strangely i encounter a error in the output of preference matrix from the analysis. To illustrate, pl see the following dataframe of a design with the response and preference collected as shown below: design<-structure(list(`Product X` = c(3, 1, 4, 2, 4, 2, 1, 3, 4, 2, 4, 2, 1, 3, 4, 2, 4, 2, 3, 1), `Product Y` =
