similar to: number plot symbol in scatterplot?

Hello all, I'm trying to graph a scatterplot of a large (5,000 x,y coordinates) of data with the caveat that many of the data points overlap with each other (share the same x AND y coordinates). In using the usual "plot" command, > plot(education, xlab="etc", ylab="etc") it seems that the overlap of points is not shown in the graph. Namely, there are

I have continuous variables x, y, z. The plot of the data looks like this: y | z=1(o), 2(@), 3(#), 4(*) | |* * * | | |# # # # | | |@ @ @ @ | | o | o | o | o |o ------------------------ x The correct model appears to be: if z==1, y~x+z; else y~z (y~z + z:x isn't it) How can I express this model in lm()?

If I used a groupedData object, if I do fit<-lme(blah) then plot(augPred(fit)) produces a nice trellis plot of the data along with the fitted lines However I find that the lines and the data points are in the same colour (light blue against a medium grey background). Is there a way to make the lines in a different colour (e.g. black)? It would also be nice if the line were plotted after the

Hi, I am new to R and I would like to display an image on a plane in a 3D plot, i.e. I would like to be able to specify a theta and a phi parameters like in the function persp to display a 2D image on an inclined plane. Regards, vincent [[alternative HTML version deleted]]

I'm working with a lot of data right now, but I'm new to R, and not very good with it, hence my request for help. What type of graph could I use to straighten out things like... http://r.789695.n4.nabble.com/file/n3711389/Untitled.png ...this? I want to see general frequencies. Should I use something like a 3D histogram, or is there an easier way like, say, shading? I'm sure these

Hi, I use panel.points to add points to a xyplot graphic. But I like to use the sunflowerplot to plot my points because this is very superimposed. It is possible to use this? I try but it dont work directly. It may be need to put this function inside a panel.??? Thanks Ronaldo -- Where there's a will, there's a relative. -- > Prof. Ronaldo Reis J?nior | .''`.

I am used to using R under unix. I have a problem with R under Windows-2000: Suppose I have a plain text file code.r full of R code that I want to source into R. My problem is that Windows invisibly tacks ".txt" onto the end of the filename (the name looks like code.r but it is really code.r.txt). How to get windows to both allow me to call it code.r (for real! Not

I'm having a bit of trouble finding and understanding the correct function to make numeric vectors to feed the sunflowerplot function. I have 33k points to show and I want to do better than the standard scatter plot. I gather that I need two vectors (x and y) of the same count containing the "center" value of each bin. FYI - I have two pieces of data: 1 - x axis - time in days of

Hello, R-help, does anybody have already a work-around for the problem that the formula version of sunflowerplot() throws an error when provided with a value for xlab (or ylab) different from NULL: > sunflowerplot( Sepal.Length ~ Sepal.Width, data = iris, xlab = "A") Error in model.frame.default(formula = Sepal.Length ~ Sepal.Width, data = iris, : variable lengths differ

Hi, I create a plot using sunflowerplot, I need to highlight one point to show its importance. What suggestion you have to accomplish this? Thanks, Aden [[alternative HTML version deleted]]

Hello everybody, I'm trying to understand how to draw a smoothed scatterplot on a geographic map with R. Have a dataframe with point locations (long, lat) and was able to simply plot these points on a shp map by using the maptools package. However, instead of having simply the raw points on the map, I would like to have a "smoothed" scatterplot of the same superimposed on the map.

Hello, I apologize that this is off-topic. I am seeking information on perception of graphical data, in an effort to improve the plots I produce. Would anyone point me to literature reviews in this area? (Or keywords to try on google?) Is this located somewhere near cognitive science, psychology, human factors research? For example, some specific questions I have are: I recall as a child

I suspect the problem stems from the fact that there are a couple of NA values. > sunflowerplot(lastoto,maxear) Error in rep.int(i.multi, number[number > 1]) : invalid number of copies in rep.int() So I used the subset command to get rid of the cases with NA hell<-subset(ChinOtoMayB,is.na(lastoto)==FALSE) Then it worked perfectly sunflowerplot(hell$lastoto,hell$maxear) Is

Anyone who can help me with the following question? How can I add weight to [x,y] coordinates on a graph/scatterplot? Background: Monte Carlo simulation generated 730,000 [x,y] coordinates with a weight attached (from 0-0.5). Both x and y are rounded and fit on a raster with x-axis 0-170 months (smalles unit = 1 month) and y-axis 0-6 (smallest unit=0.1). I would like every [x,y] to add its

Dear fellow R users, I would like to draw a "sunflowerplot" because I have data (decade by month) that plots multiple times on the same x-y co-ordinates. Further I would like to colour each of the points/sunflower leaves on the plot according to the group they belong to (i.e. which type of event each represents within that decade and month). I thought that this would be relatively

I'm trying to do a sunflowerplot of Galton's data, with both regression lines and data ellipses, and I must be doing something wrong, because the lines do not intersect at \bar{x}, \bar{y}. The problem is likely in the line for x.y, but I don't know how to specify that correctly. The data is read in grouped form( galton), and then ungrouped (galton2): galton <-

Hi all -- So I'm trying to use lattice graphics, but I want to use a sunflower plot, which doesn't seem to be part of lattice. No problem, I put together the following code, which mostly works -- *except* for the first graph it generates. If it opens the graphic device, then it draws the xygrid, clears the device, then draws the sunflowerplot. All subsequent output operations work

Is there any function to show the points like this example of SPSS? http://biostatistic.de/temp/reg.jpg The point size should represent the number of data at this point. with regards Knut Krueger
