Dear R experts, Suppose I have a data frame of three variables: > foo <- data.frame(row=1:5, col=1:3, val=rnorm(15)) > foo row col val 1 1 1 -1.00631642 2 2 2 0.77715344 3 3 3 0.17358793 4 4 1 -1.67226988 5 5 2 1.08218836 6 1 3 1.32961329 7 2 1 -0.51186267 8 3 2 -1.20990127 9 4 3 -0.57786899 10 5 1 0.67102887 11 1 2

Dear ExpeRts, I am trying to plot a bunch of growth curves and would like to get some more control over groups and line colors than I seem to have. Example: # make some data dat <- Orange dat$group <- ifelse(dat$Tree%in%c('1','4','5'), 'A', 'B') # plot xyplot(circumference~age, dat, groups=group) # now use lines to make the growth curve more

Dear ExpeRts,t I am trying to read tab delimted data produced by somewhat brain dead software that seems to think it's a good idea to have an extra tab character after the last column - except for the header line. As explained in the help page, read.delim now assumes that the first column contains the row.names (which is not even wrong) but now and all col.names get shiftet by one column.

Hi! In a current project, I am fitting loess models to subsets of data in order to use the loess predicitons for normalization (similar to what is done in many microarray analyses). While working on this I ran into a problem when I tried to predict from the loess models and the data contained NAs or NaNs. I tracked down the problem to the fact that predict.loess will not return a value at all

Dear R Experts, I am trying to produce a legend for a series of plots which are generated in a loop. The legend is supposed to look like this: 2000: gamma=1.8 where gamma is replaced by the greek letter and both the year and the value of gamma are stored in variables. Everything works fine as long as I have only one data series: year = 2001 g = 1.9 plot(1) legend('top',

I am working off an example from Deepayan Sarkar's Lattice:Multivariate Data Visualiization with R. I am trying to create Figure 5.6, essentially, but I would like to be able depict different metro areas. These of course have different lat/longs, so I need to make different graphs. BUT (and this has been the tricky part), I would like to produce graphics for each metropolitan

I'm just starting to work with lattice graphics, and am having difficulty understanding how to control various graphic parameters (font sizes, etc.). [I'm actually using xyplot via plot.effect() in the car package, and would like to be able to set some global defaults.] I read ?xyplot and ?trellis.par.set-- which contains no complete list of parameters, just a reference to

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

I'm having problems copying and saving lattice graphs using R-1.4.0 under Win2k. It seems I've see this alluded to recently in R-help. If I do the following example: > data(quakes) > xyplot(long ~ lat , data = quakes) And then try to copy or save the graph as either a metafile or bitmap or if I use any of the bitmap/metafile devices via (for example) >

Hello R-experts! When I produce a plot R takes avoids overlapping axis labels in order to maintain readabilty which is great. But now I have written a little custom plot function in which I set my own labels and label positions after generating the actual plot: axis(..., lables=c('A', 'B', 'F', 'G', 'M'), at=mypositions) As you may have guessed: This is

Hi, under the new version R 2.7.1 I can't use WinEdt. It seems that there is a bug in that version. To use older versions of the package RWinEdt doens't bring success. The Use of R 2.7.0 doesn't cause that Problem.

Hey, folk. I am trying to get many figures by using the function "xyplot" in the library "lattice". I tried to using the loop to finish it quickly. But I cannot open the saved file after I run the program. But if I use the function "plot" to get other simply figures, it can work. So I want to ask how I can get the saved figures by using "xyplot". The

Hi All, I'm trying to add a map on the following lattice plot, but not correctly... can anyone help please... R Code: require(lattice) us.map <- map(plot = FALSE, fill = TRUE) Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes, panel = function(...) { panel.polygon(us.map$x,us.map$y) panel.xyplot(...) } ) Any help would be

Hola a todos, Tengo que construir un gráfico para una base de datos que tengo en el que representar para los individuos de esta base su altura vs peso en función de su edad. Para ello, hay que utilizar los gráficos condicionados. En primer lugar usé la función coplot pero cargando el paquete lattice se pueden utilizar funciones que generan gráficos más completos, como es el caso de la función

Hello R-experts! I am using R Version 1.7.1 (2003-06-16) on a Debian Linux box and I have discovered an odd result when plotting data involving dates. Please try this minimal example: a = seq(ISOdate(2000,1,1), ISOdate(2001,1,1), "months") b = 1:13 plot(a,b, col="red") What I get is a plot that looks as expected except the x-axis is mostly red. Can anyone reproduce this

Hi, I try to make a xyplot withou colors. I try: pdf(file="test.pdf") trellis.device(color=F) Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes) dev.off() the graphic is showed without colors in a X device but it dont work saving directly on pdf device. How I made to put color off in trellis device? Thanks Ronaldo -- 2ª lei - Na

Dear all, if I plot a lattice xyplot like: library(lattice); require(stats); Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes) How can I manipulate the group title format (here: Depth)? Like the font size, position, etc. Best Marcus

I just built 0.61.2 on an hpux-10.2 system. WHen I do a demo I am getting : > data(quakes) [1] "quakes" Warning: invalid 'cutoff' for deparse, used default Every statement seems to trigger this response. I also built the march17 snapshot and it does not have this behavior. March 17 snapshot has one problem that I noticed: when I built a contributed lib with data, and if

Hi all, In lattice plots, is there any option to position the panel strips with text below each subgraph, instead of above? i.e. in: Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes) ,is there any way to make "Depth" appear below the subgraphs, instead of above? I've been looking through the lattice documentation and the list
