Hello, I am drawing a boxplot using bwplot in lattice. I would like to learn how to draw a thicker median line instead of the default setting. Thank you. Code bwplot(........, pch=rep("|",2)) Elaine [[alternative HTML version deleted]]

Dear list members I want to analyze separately the months of a time series. In other words, I want to plot and fit models for each month separately. Taking the example of http://a-little-book-of-r-for-time-series.readthedocs.org/en/latest/src/timeseries.html births <- scan("http://robjhyndman.com/tsdldata/data/nybirths.dat") birthstimeseries <- ts(births, frequency=12,

Hi All, I'm still pretty new to using R - and I was hoping I might be able to get some advice as to how to use 'apply' or a similar function instead of using nested for loops. Right now I have a script which uses nested for loops similar to this: i <- 1 for(a in Alpha) { for (b in Beta) { for (c in Gamma) { for (d in Delta) { for (e in Epsilon) { Output[i] <-

I have Function Function* F; and one of its basic blocks BB I want to insert this BB into a new function without remove it from the original according that BList is the list of the basic blocks of the newFunction BList.insert(BB); but I don't want to call BB->removeFromParent(); and without this method it give me error that BB is already in a container is there another function that get

Hello I'm a population ecologist and use R for all my stats and modelling. Recently I have been using R to numerically solve integral projection models. This involves constructing several large matrices. The current code by Easterling (Size-specific sensitivity: Applying a new structured population model. Ecology, 2000, 81, 694-708) uses nested loops to construct the matrices. To speed up the

Hi, there: I am wondering if there is a quick way to "reverse" a list like this: t0 <- list(a=1, b=1, c=2, d=1) reverst t0 to t1 > t1 $`1` [1] "a" "b" "d" $`2` [1] "c" thanks. -- Weiwei Shi, Ph.D Research Scientist GeneGO, Inc.

Hi, I am R beginner and am trying to figure out how to generate a complete list of species for every point, visit, and year. The code below is close but does not give me a list of species for every point, visit, and year in my data set. spplist<-unique(sumPtCt$Species) spplength<-length(spplist) Pointlist<-unique(sumPtCt$Point) Pointlength<-length(Pointlist)

Hi everyone, For reasons beyond the scope of this message, I'd like to append a NULL element to the end of a list. tmp0 <- list(a=1, b=NULL, c=3) append(tmp0, c(d=4)) ## works as expected append(tmp0, c(d=NULL)) ## list with a/b/c only Given that I could use tmp0$a <- NULL to remove 'a', I seem to understand why appending NULL returns me the original list... But how should I

Hi, what is the proper of of "passing a missing value" so I can extract the entire i-th row of a matrix (in a list of lists) without pre-computing the number of cols? For example, if I know that the matrices have 2 columns, I can do the following: set.seed(1) x0 <- lapply(1:10, function(i) replicate(4, list(matrix(rnorm(10), nc=2)))) lapply(lapply(x0, '[[', 3), '[',

Hi, I'm working on an S4 class that is expected to behave like an array. I have some difficulties when defining '[' and I wonder if someone could point me to the right direction: 1) Call the S4 object "obj" 2) Assume dim(obj) = c(10, 4, 2) 3) Suppose someone calls: obj[1:3,] , which is a mistake, given dim(obj); how do I detect such situations? Thank you very much for

Hi, If you are not already tired of so many io controller implementations, here is another one. This is a very eary very crude implementation to get early feedback to see if this approach makes any sense or not. This controller is a proportional weight IO controller primarily based on/inspired by dm-ioband. One of the things I personally found little odd about dm-ioband was need of a dm-ioband

Hi all, With this series of patches, you can determine the owners of any type of I/Os. I ported the previous version to linux-2.6.26-rc2-mm1. This makes dm-ioband -- I/O bandwidth controller -- be able to control the Block I/O bandwidths even when it accepts delayed write requests. Dm-ioband can find the owner cgroup of each request. It is also possible that OpenVz team and NEC Uchida-san team

Hi, I'm new to this mailing list and to R-programming so if the question is stupid I apologize. I have to create a package, which includes an S4-class called "BList". For objects of this class I implemented a method "show", which displays the first 15 data-lines of the object. I further implemented a method "showall", which displays the whole data in the object.

Hello: I would like to be able to do a 3D scatter plot from 3 variables, 2 independent and 1 dependent. The closest R function I could find for this is "cloud". However cloud uses, as input, a matrix where the value of each matrix element is the dependent variable value at that matrix coordinate. My problem is that the independent variable values are floating point and can be of
