simplification of code using stamp?
Hi I have the following code which I would like to simplify. Id does linear regressions and returns the r-squares, and the coefficients. It runs slow, as it is doing the regressions for each - is it possible to get the values in a dataframe which looks as follow: expert | xx | seeds | r.squared | slope | intercept Thanks in advance, Rainer library(reshape) rsqs <- as.data.frame(

Multivariate Maximum Likelihood Estimation
Hi, I am trying to perform Maximum Likelihood estimation of a Multivariate model (2 independent variables + intercept) with autocorrelated errors of 1st order (ar(1)). Does R have a function for that? I could only find an univariate option (ar.mle function) and when writing my own I find that it is pretty memory-consuming (and sometimes wrong) so there must be a better way. Thanks, KB

Strange warning in summary.lm
Dear useRs, Lately I noticed a strange warning in the summary of a lm-object. Any idea what this warning is about? I'm using R 2.5.1 on Win XP pro. > x <- rnorm(100) > y <- rnorm(100) > summary(lm(y~x)) Call: lm(formula = y ~ x) Residuals: Min 1Q Median 3Q Max -1,77809 -0,68438 -0,04409 0,63891 2,30863 Coefficients: Estimate Std.

A rebel boxplot question
Dear R list members I am trying to improve a boxplot with 2 data sets. I run somethinkg like boxplot(data1 ~ month, add=F, col = "red", ...) boxplot(data2 ~ month, add=T, col = "blue", ...) The problem is that the data from February are missing for data2, so R think that must take little more space between the data classes in data 2 and then both data gropus are not aligned.

Logical statements and subseting data...
Hi, I'm scratching my head as to why I can't use the subset() command to remove one line of data from a data frame. There is just one row (out of 45840) that I'd like to remove and it can be identified using.... > dim(raw.all.clean) [1] 45840 10 > subset(raw.all.clean, Height.1 == 0 & Height.2 == 0) Sample.Name Well SNP Allele.1 Allele.2 Size.1 Size.2

ggplot-How to define fill colours?
Dear R's (most likely Hadley), I want to build a stacked bar plot where I would like to define which colours will be used for each of the groups. However, I do not seem to find a way to do this, even if I've been looking over many places. I have tried several variations, and my final try was this code, but I still do not manage to get the colours as I pre-define. Any hints about how

program avail. for simulating spatial patterns?
Hi all, I am wondering if there is a function available in R for simulating spatial distribution of objects (plants in this case) in order to simulate sampling of a population . Specifically, I would like to be able to change the spatial correlation of individuals. I don't want to reinvent the wheel if it already exists. Thanks, Wade

cumsum
Hi, my problem belongs to the basic ones. I want to get cumulated sum over the matrix columns by one command (if such exists). Ordinary R's cumsum(x) when x is: [,1] [,2] [1,] 1 5 [2,] 2 6 [3,] 3 7 [4,] 4 8 yields: 1 3 6 10 15 21 28 36 I want: [,1] [,2] [1,] 1 5 [2,] 3 11 [3,] 6 18 [4,] 10 26 Is there any command to do so?? best,

shading of curves with polygon
Hello again With the poylgon function it's possible to plot shaded areas under a curve. But somehow it connects the start and the endpoint of a line and fills whats between them. I would actually like to set the boarders of the shading by two min and max curves, but I failed. i tried stl like: polygon(min, max, border=0), where min and max are my curves plotet by plot(max) lines(min)
