Hi, I'm trying to create a stacked bar plot with the satisfaction scores from a customer satisfaction survey. I have results for three stores over several weeks and want to create a weekly graph with a stacked bar for each store. I can flatten the dataframe into a table with absolute frequencies, but I can't find how to get relative frequencies. My dataset looks similar to the example

I have just setup a VPN connection three sites using IPCOP. Everything seems to be talking ok, apart from browsing the network neighborhood. There are no NT/Win2K/XP servers running on any of the sites, all sites are just running win98 pc's using tcp/ip. I have tried configuring all PC's to be on the same workgroup and setup sharing, but still each site can only see the pc's

Hi everyone, I suspect this is an easy task however I've not been able to accomplish it. I'd like to create an mtext title which has certain words bold, the rest not bold. So far I've been able to create one which is all bold, one which is all not bold and one which has bold and not bold superimposed on one another. Any suggestion would be appreciated. Many thanks, Joe Retzer # Not

Hello All: I am looking for you help. I am trying to replicate the results of an example found in Alan Agresti's "Categorical Data Analysis" on pages 267-269. The example is one of a 2 x 2 cross-classification table of ordinal counts: job satisfaction and income. I am able to get Agresti's results for the independence model (G^2 = 12.03 with df = 9) assuming as he does that

You may want to rethink your whole approach here: 1. Pie charts are usually a poor choice of graph, there are better choices. 2. Adding percentages to a pie chart is a way of admitting that the pie chart is not doing the job. 3. If you want people to compare percentages, then a table is what is needed. 4. A pie chart with percentages added is essentially a colorful but poorly layed out table.

Hello, I?m wondering if anyone can offer advice on the out-of-memory error I?m getting. I?m using R2.12.2 on Windows XP, Platform: i386-pc-mingw32/i386 (32-bit). I am using the quantreg package, trying to perform a quantile regression on a dataframe that has 11,254 rows and 5 columns. > object.size(subsetAudit.dat) 450832 bytes > str(subsetAudit.dat) 'data.frame': 11253 obs.

Hi, (1.) How is it possible to get automatic a "lower triangle of correlation matrix" ? h.cor <- cor(dat,use="pairwise.complete.obs") zz <- lower.tri(h.cor,diag=T) ### that's not what i wish and "wrong" ? results <- matrix(unlist(h.cor[upper.tri(h.cor,diag=T)])) results <- matrix(unlist(h.cor[upper.tri(h.cor,diag=T)]),5) Must i take the lowest

Dear Friends, I had performed anova test on certain data frame (Health Care Management) and got results [summary(aov)]. I am new to R and also some extent to Statistics. Can somebody help me how should I interpret these figures. I feel difficulty in interpreting values and respective rows and columns. The following is the result to which I request interpretation: > anova.stress$effects

Hello Nabble users, A question about having two y axes on a chart. I'm trying to show on the left (first) y axis a measure used in an experiment; the x axis shows the experiment number, that has been sorted in a specific manner -- i.e. not Experiments 1,2,3,n, but could be Experiment 6,1,18,n; the right (second) y axis shows an experimental variable. The idea of the chart is to show how

Hello list! I can't seem to get this running via RS232 monitoring; I've been told that NUT won't support serial connections, and find this hard to verify. Does anyone else have this running on the SU10KRT3U via RS232? If so, what driver did you use? I'm getting no satisfaction from the "tripplite" driver; upon upsdrvctl start, I get "Failed to find UPS - giving

Hey R'rs, So im sick of dealing with ESRI products and am looking to stream line a process i now use GIS to do using R. I have made a lot of maps using R but have not yet seen a map that puts pie charts within the map to help represent data like the attachment. http://r.789695.n4.nabble.com/file/n2318816/template1.bmp I found Tanimura et al. work "Proportional Symbol Mapping in

Hi, I have a 2D chart that is divided into four quadrants, I, II, III, IV: plot(1:10,ylim=c(0,10),xlim=c(0,10),type="n") abline(v=5,h=5) text(x=c(7.5,7.5,2.5,2.5),y=c(2.5,7.5,7.5,2.5),labels=c("I","II","III","IV")) I would like to fill each quadrant with a background color unique to the quadrant. Does anyone know how to do this in R? Thanks, --

Dear all, I would like to create a stacked area chart to show the development of species biomass over time. Since it is intended for publication I need to prepare in black and white. I have tried to modify the "stackedPlot" function submitted to this list by Christian Lasarczyk on Tue, 16 Aug 2005 using shading lines rather than colors to distinguish between the species.

Hi! I am using R to process some community survey data. Several item responses are recorded via a 7-point Likert-Scale. As I have coded the responses, 1 represents high agreement, and 7 high disagreement. This of course impacts the coefficients in a linear regression (of example agreement to self-perception measures on housing satisfaction). For some purposes, in order to make the coefficients

I am having trouble finding out how to adjust the position of labels on pie charts. For the small wedges, many of the labels overlap making it impossible to read. Is there any way to offset the labels so that they don't overlap? Adam Green USGS Patuxent Wildlife Research Center [[alternative HTML version deleted]]

Hi, I have shifted to linux fews months ago with a great satisfaction and i don't want to use windows anymore. But... i need to use a windows program protected by a dongle.
