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 (found for '(xl...

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 | .''`. UNIMON...

A sunflowerplot crossing two categorial variables with NAs fails: ### sample: start ### set.seed(20) a <- c(letters[1:4]) z <- c(letters[23:26]) fa <- factor(sample(rep.int(a, 1000), 100, replace=T), levels=a, ordered=T) fz <- factor(sample(rep.int(z, 1000), 100, replace=T), levels=z, ordered=T) s...

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 t...

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]]

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...

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 the year from 0 to 363.98 2 -...

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( galto...

...e 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 fine, as does rerunning the code with the graphic device open. What's going on? How can I fix this? I tried looking through the family of dev.* to no success. I can use trellis.device to open the device, but that causes the same problem. -- Chris...

If I make a scatterplot and several (e.g. 5) points lie on top of each other at a given x,y location I would like the plot symbol to be the number of superimposed points (e.g. "5"). Could someone please tell me how to do this in R? Thanks! Bill Simpson

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

...heights on a bar graph? (What about areas in bar graphs with non-uniform widths?) Scatter plots of microarray data often attempt to represent thousands or tens of thousands of points, but all I read from them are density and distribution --- the gene names cannot be shown. At what point, would a sunflowerplot-like display or a smooth gradient be better? When two data points drawn as 50% gray disks are small and tangent, are they perceptually equivalent to a single, 100% black disk? Or a 50% gray disk with twice the area? What problems are known about plotting with disks --- do viewers use the area or...

Hello, I wrote a wrapper for symbols() that produces a bivariate bubble plot, for use when plot(x,y) hides multiple occurrences of the same x,y combination (e.g. if x,y are integers). Circle area ~ counts per bin, and circle size is controlled by 'scale'. Question: how can I automatically make the smallest circle the same size as a standard plot character, rather than having to

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

Dear all, (Mac OS X 10.4.11, R 2.6.0) I have a quantitative dataset with a lot of Na?s in it. So many, that it is not possible to delete all rows with NA?s and also not possible, to delete all variables with NA?s. Is there a function for a principal component analysis, that can deal with so many NA?s. Thanks in advance Birgit Birgit Lemcke Institut f?r Systematische Botanik

Dear R-helper, I want to plot the following-like data: x y 1 1 1 1 1 2 1 3 1 3 1 4 ...... In the plot that produced, I don't want to show the usual circles or points. Instead, I want to show the number of replicates at that point. e.g. at the position of (1,1), there are 2 obsevations, so a number '2' will be displayed in the plot. Is my narrative clear? Is there a way to make the

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
