I am trying to do a histogram lattice plot and I would like the histogram to be filled with a different colour in each panel. Note: I want every bar in each histogram to be the same colour, but that there should be different colours *between* histograms. Can't seem to get this to work. I thought that something like the following would be a goer: set.seed(42) X <- rnorm(200) A <- factor(sample(letters[1:5],200,TRUE)) DF <- data.frame(x=X,a=A) print(histogram(~x|a,data=DF,col=2:6,type="count", panel=function(x,...,subscript...

I have data like: a <- rnorm(20000) b <- rep(FALSE,20000) b[sample(1:20000,15000)] <- TRUE Using Lattice graphics, I can produce two side-by-side histograms quite easily by: histogram(a | b) However, I would like to produce a "single" histogram with two bars within each bin, one for each group, as the groups are in reality very slightly different from each other. The difference isn't evident unless one "overlays" the two...

TestHistogram_A is a function that plots a histogram, then returns 3. For me it fails to display the plot, at least in the order given below. TestHistogram_B is a function that plots a histogram, then exits. The only difference between the 2 functions is that B does not return 3. It displays the plot. This problem does not occur when histogram is replaced by boxplot Their use

...s "histogram". I have put the plotting in a separate function, plot.histogram(), which is called from hist.default if plot=T, and I have made a lines.histogram() (calling it "lines", is that a wise choice? It seemed most natural, but then again....), which can be used to overlay histograms on existing histograms. Here it is obviously a lot of room for improvement. E.g. calling plot.histogram() with multiple histogram objects could produce a plot where coloumns representing the same values are grouped, I haven't addressed that. The code is below my .sig. As you can see, there are...

Hello, This is not exactly an R question, but I suspect that there is an R procedure that does what I am calling (for lack of a better name) "histogram ranking". I'm trying to evaluate a set of regression features by segregating by target class and comparing the feature histograms. My idea is that if the histograms are the same for two different classes then there is no predictive power in those features. Conversely, if the histograms are different then there is probably some predictive "juice" that we can squeeze out of the features with regression. The histo...

...not work for histogram(). par(mfrow=c(3,2)) for (i in 1:20) histogram(rnorm(100),main="",cex.axis=.8) I thought this was simply set in par() but it doesn't seem to do any good. Thoughts.

I would like to add some vertical lines to a lattice plot of histograms. What I am after is a lattice version of abline(v = 1234). The lattice histogram plot is just: histogram( ~ LTSE | approach, data = arrivals) Can anyone point me in the right direction for this?

I hope there are many of us that agree 100% with Bill. Bad practice, as enshrined in the default behaviour of histogram, should be discouraged. We should aim to introduce density-based histograms from the outset, and the default behaviour of histograms in many packages acts agains...

...(mfrow=c(7,7)) for (i in 1:49) hist(RATDACOM[SUBJNO==i],breaks=0.5+(0:6), main="",xlab="",ylab="",xaxt="n",yaxt="n") (Don't think about what RATDACOM and SUBJNO are.) I get an error Error in plot.new() : Figure margins too large. 36 histograms with mfrow=c(6,6) work. But the 36 histograms are then so small that I wonder why 49 do not fit. It seems that though I have main="",xlab="",ylab="",xaxt="n",yaxt="n" the area reserved for axes and labels is almost as large as it would be if I would...

been puzzling over this for a day. Summary integer variable to use with histogram, 170,000 rows. Value is day of year. Hist works, lattice histogram with nint does not work (spurious spikes in display), lattice histogram using breaks=c(0:365) works fine. Spike values appear to be sum of two adjacent bins. Want to know if this is a familiar problem, and what the recommended work-around is.

Hi I would like to superimpose group-specific densityplots on top of an overall histogram using panel.histogram and panel.densityplot. Furthermore, I would like to automatically adjust the range of the y-axis to take into account the ranges of both histogram and densityplot. This last part is where I have a problem. I believe using the prepanel argument of histogram is typically the way to go,

Earlier, I posted the following question: I want to superimpose histograms from three populations onto the same graph, changing the shading of the bars for each population. After consulting the help files and the archives I cannot find out how to do this (seemly) simple graph. To be clear, I want - a single x axis (from -3 to 18) - three groups of bars forming the hist...

I wanted to do two things, add histograms where the breaks of one histogram is a subset sequence of the other, and get a histogram plot from a histogram object. I found no function to do these things and got no response on r-help, so I started doing it myself. I think I hav...

I would like to make a scatterplot, with a histogram of the x and y variables above and to the right . I can use layout to set up the areas, and hist(x,y) works fine for the upper histogram. However, I need a rotated histogram on the right, and I don't know how to do this. I've seen a solution with a bar plot on the right, but I'd like to use a histogram. Do you know how I can do

Hello, I'm trying to superimpose a line plot onto a histogram but I'm not having any luck. I've attached the dataset. What I did was: > hist(data,freq=F) Now I'm trying to superimpose the following points with a line connecting them onto the histogram: x y 100 0.535665393824959 200 0.212744329736556 300 0.0844933242968584 400 0.0335572838043417 500

I woud like to plot cumulative histograms. Specifically, I have data like Sex M M F M F F M F Height 6 6.3 6.1 5.5 7.2 6.2 5.9 6.0 .... and I want to plot a histogram of the distribution of all heights, colouring the histogram bars according to sex, for example | o | oo o | o oo ** o o =...

Dear users, I would like to plot several histograms superimposed on the same panel with different colors, with superimposed polygons appearing with transparency effects. I also want estimated densities to appear on the same plot. For several reasons, including that I like it, I want to use the lattice package. I have several questions regarding the...
