similar to: lattice barchart sorting and coloring

Hello! I apologize - I never used lattice before, so my question is probably very basic - but I just can't find the answer in the archive nor in the documentation: I have a named numeric vector p of 6 numbers (of the type 6 numbers with people's names to whom those numbers belong). I want a simple bar chart. I am doing: library(lattice) trellis.par.set(fontsize=list(text=12)) #

Hi, I have a small problem when using barchart. I have the following data: letters a 6 f 18 1 a 15 10 j 12 9 i 12 4 d 9 5 e 6 The data is from a survey and summaries the alternatives selected in one question. The idea is to have a bar chart illustrating the count of each selection in descending order. The data frame is already ordered in

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

Hi, What determines the order of the rows in a barchart? Cheers, Geoff. Here is my code, and the data follows. If I have z in alpha order, the barchart is in some order I can't determine. I originally tried rownames(twater)~twater$Cat, but the chart wasn't in rownames(twater) order either. library(lattice) twater<-read.csv("totalwater.csv",strip.white=T)

Hi list, I am unsuccessfully trying to produce a serious of trellis barcharts from within a for-loop. The barcharts work outside the loop. What am I missing? Example attached. Thanks Herry #XXXXXXXXXXXXXXXXXXXXXX trellis.device(bg="white") trellis.par.get("fontsize")->fontsize fontsize$default<-16 trellis.par.set("fontsize",fontsize)

I have searched the archives and instructions high and low but have not found what I need. I have a dataframe named Data with columns: AdjResND0 - the numeric result Parameter - the classification (chemical name) Sort - the order I want the chemical names to appear, with leading zeros so all are the same length Client.Name - the sample name I am trying to generate a series of 1 page barcharts,

Hola a todos: soy nueva en R así que es posible que la pregunta sea simple, pero no encuentro la solución. El caso, quiero hacer un gráfico de barras sencillito, pero con una linea horizontal que represente la media. Pues bien, si hago el gráfico sin aplicar la linea, no hay problema: ----- barchart(web[,2] ~ web[,1], col="#2C575D", ylab=colnames(web)[2],

Hi List, I have recently upgraded to opensuse10.2 and R 2.5 (compiled from source). Now, whenever I use plot the y-axis and labels are black blotches while x-axis and labels are fine. Using demo(graphics) this occurs with plot/boxplot/hist/pairs/coplot but not in the pie graphs and in the "The level of Interest in R" plot, which uses axis to define the y-axis. I presume this has to

Perfecto! muchas gracias Carlos; la verdad que estuve un buen rato intentándolo, pero aún no comprendo la estructura de lattice, así que modificaba cosas un poco al tuntun. Tengo otra cuestión un poco más controvertida, no sé si este será el foro adecuado para proponerla o supondrá un debate innecesario.... Como os decía, acabo de iniciarme en R, y estoy explorando las opciones de visualización.

Dear List, I am want to plot my data in increasing order using the lattice barchart() function. I used order() to put my data in the order I want, but when I plot it I get the original order of the data. I think this has to do with the row index number since order() does not re-number the rows in the new order but instead keeps the original row numbers and puts them in a different order. For

Hi Listers, Surely, I just have a mental block and there is a more elegant way of creating a summary count (other than extracing it from ftable). I''d like to create a new data.frame containing counts of spell by loc ie have three columns showing spell,loc,count. Below the data.frame... Any help appreciated Thanks Herry spell loc 101 Parts 1 102 Overall 2 105 Parts 1 106

I've a data frame with this structure: 'data.frame': 1987 obs. of 11 variables: $ site : Factor w/ 24 levels "B(W)","BC-1",..: 1 1 2 2 2 1 1 1 ... $ sampdate : Date, format: "2000-07-18" "2000-07-18" ... $ tclass : Factor w/ 8 levels "Annelida","Arachnida",..: 1 5 5 5 5 ... $ torder : Factor

Hi List, when loading library(rgl) I get error "RGL: GLX extension missing on server". I have Mesa and xgl installed, but xgl info sais its an highly experimental code. Does this mean I shouldn't bother for a while with opengl or are there alternatives?

I'd like to plot coefficients from glm result. with barchart, coefficients are ordered by the names of factors and I'd like to order them by values (or abs(values)). to do that, I've ordered the vector of coefficients but it's plotting the same thing. I'm working R 1.6.2 on win98. Thanks is it possible to do that with standard graphical function?

List, I am trying to extract summary statistics from a data frame with several variables (and NAs) into a dataframe with the columns: Variablename (ie the colnames of original data), mean, stdev, max, min, Valid N, Missing Values. Extracting the statistics is straightforward using stack and aggregate. However, I haven''t succeeded in obtaining the number of Missing Values. I can extract

Dear list, I am having troubles increasing the fontize when plotting a variogram{gstat} and its model (vgm) with plot and using jpeg(). Also the resolution in the jpeg call does not work. I am using R2.4 on Mandriva 10.2 linux. I can change fontsize with cex.axis in a normal plot, so I presume it has to do with plotting the variogram model. Any help on how to increase the font size and

Last line in the following (updated) code produces the error require(raster) require(rts) require(stringr) r <- raster(ncol=100, nrow=100) values(r) <- runif(ncell(r)) stack(r)->s r->rs for(i in 1:23){ rs[]<-r[]*i addLayer(s,rs)->s print(nlayers(s)) } dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12)))

Folks at R help, I can't quite get the panel function to work the way I want within barchart. I guess I'm still not understanding how to piece together multiple panel arguments, especially when "groups" is specified. Example: I want to be able to add the value of "yield" to each section of each bar in this graph: barchart(yield ~ variety | site, data = barley,

When I use barchart (with default formatting options), I get bars whose lengths/heights are not proportional to their value. For example: http://drop.io/wbagm6s/asset/capture-png Many of the values in this chart are 1; however, because the blue bars extend to the left of the "0" tick mark, those bars appear to represent higher numeric values. Is there a way to make the length of the

Hi Herry, This is probably due to a call to strptime (or similar). No, it doesn't accept %Y-%m as a valid format. Maybe add a constant day to all the dates as that will work: dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12))) timelst<-paste(unlist(dt['year']),unlist(dt['month']),"01",sep="-")
