...nning into a problem in positions where the values to plot are too close together to print the text without overlap. The simplest way I can think of to solve this (although there may be other ways?) is to create a new numeric vector whose values are as close as possible to the original vector, but spread out to a given minimum difference. For example, take the following vector: > x <- c(1,2,seq(2.1,2.3,0.1),3,4) > x [1] 1.0 2.0 2.1 2.2 2.3 3.0 4.0 > However, suppose I don't want to plot any of these points with less than 0.5 between them. The problem could be solved by a functio...

I'm trying to figure out how to write a r function that will calculate the extreme spread of a group of points given their (x,y) coordinates. Extreme Spread is the maximal Euclidean distance between two points in a group ex.spread = max{ sqrt [ (xi-xj)^2 - (yi-yj)^2 ] } for i not equal to j I have 60 levels to apply this to. There is the combination function in the dprep package...

Hi all, I tried to read data from Excel spread sheet with using read.csv(file.choose()) and read.delim(file.choose()) but its showing " *ÐÏ.à.*." and also i tried with read.table(file.choose()) then its showing " * V1 1 ÐÏ\021ࡱ* " can any...

I am trying to create plots within a for loop and output them to a pdf. Here is a working example using plot: gg <- data.frame(datadate=1:4, spread=5:8) pdf() for (i in 1:3) { plot(gg$datadate, gg$spread, main=i) } dev.off() I am trying to learn more about ggplot2 so I try a slight modification and it doesn't work. Anyone know how to do this using qplot in ggplot2? gg <-...

...#39;s bug reporting system for contributed packages. 2. This is _not_ a bug in svm() in `e1071'. I believe you forgot to take sqrt. 3. You really should use the `tot.MSE' component rather than the mean of the `MSE' component, but this is only a very small difference. So, instead of spread[i] <- mean(mysvm$MSE), you should have spread[i] <- sqrt(mysvm$tot.MSE). I get: > spread <- rep(0,20) > for (i in 1:20) { + spread[i] <- svm(y ~ x,data, cross=10)$tot.MSE + } > summary(sqrt(spread[i])) Min. 1st Qu. Median Mean 3rd Qu. Max. 0.2679 0.2679 0.26...

I am looking for a good CMS based on Rails that has at least these attributes: 1. Ease of use ( as it will be used by people who are not html literate) 2. Very easy/flexible to change layout.

I was at a lecture the other day and I saw a presentation of very neat (short) animation modeling epidemic disease spread over a map region. When I ask what software they used they mentioned SAS. Do you know if there are equivalent resources in R to model the spread of disease with animation output? My search in R-help and google didn't lead to any document (though I found a couple of documents for SAS). However m...

Hi all. The environment we are working on is a Red Hat Linux 6.2, with XFree 4.0 and KDE 2.1. The wine has been compiled using egcs-1.1.2. Wine itself is latest snapshot (20010731). The application we're trying to run crashes when tries to display a dialog box using Spread controls (from Farpoint). The crash occurs during a WM_PAINT. By exploring the builind of the window, the control it is showing is a scrollbar (lpszClass="SPR32D30ScrlBar"). A very strange behaviour is that the window does not appear to be linked in the parent/sibling structure. I...

...a map of invasive species risk (1 = infested; 0 = uninfested). It started as a matrix of probabilities (developed in ArcMap) that I converted to binary with this R code: binary.matrix<-matrix(rbinom(length(prob.matrix),prob=prob.matrix,size=1),nrow=nrow(prob.matrix)) Now, I would like to "spread" the risk for year 2 of the invasion. I'd like to do this by location, so, for every cell that is currently a 1, next year it's immediate neighbors (above, below, to the right and left) would also become ones. Here is a function I came up with to attempt this (clearly, my function writ...
