restore NAs in residuals
Dear All, I have two vectors: tt = c(6.87, 7.43, 6.4, 4.5, 5.5, 5.87, NA, NA, NA, 7.7) year = 1966:1975 Residuals lm(tt~year)$res do not contain NAs for the three years of missing temperature tt. Is there a simple way to get these NAs back into the residual's vector? Thank you, Sorama [[alternative HTML version deleted]]

Understanding svd usage and its necessity in generalized inverse calculation
Dear R-devel: I could use some advice about matrix calculations and steps that might make for faster computation of generalized inverses. It appears in some projects there is a bottleneck at the use of svd in calculation of generalized inverses. Here's some Rprof output I need to understand. > summaryRprof("Amelia.out") $by.self self.time self.pct

longitudinal imputation with PAN
Hello all, I am working on a longitudinal study of children in the UK and trying the PAN package for imputation of missing data, since it fulfils the critical criteria of taking into account individual subject trend over time as well as population trend over time. In order to validate the procedure I have started by deleting some known values ?we have 6 annual measures of height on 300 children

gamm (mgcv) interaction with linear term
Hello, I am trying to fit a gamm (package mgcv) model with a smooth term, a linear term, and an interaction between the two. The reason I am using gamm rather than gam is that there are repeated measures in time (which is the smooth term x1), so I am including an AR1 autocorrelation term. The model I have so far ended up with is of the type gamm(y ~ s(x1) + s(x1, by=x2), correlation =

[newbie] pager for large matrix?
summary: I'd like a tool to use within an R session (better yet an ESS buffer) that would * (minimally) allow me to page (? la `less`) a large sparse matrix * (preferably) page row-wise (i.e., show all values for row=1 before proceeding to row=2) details: Apologies if this is a FAQ, but I didn't find anything in `help.print` or google="R pager".

Discrepency between confidence intervals from t.test and computed manually -- why?
I am sure there is something simple here I am missing, so please bear with me. It concerns the computation of the confidence interval for a population mean. The data are 125 measurements of Cs137 radation, a sample data set from Davis "Statistics and Data Analysis in Geology" 3rd ed.

help for segmented package
Hi, I am trying to find m breakpoints of a linear regression model. I used the segmented package. It works fine for small number of predicators and breakpoints.(3 r.v. 3 points). However, my model has 14 variables it even would not work even for just one breakpoints!. The error message is always estimated breakpoints are out of range. Since my problem is time related problem.

[LLVMdev] Polyhedron 2005 results for dragonegg 3.3svn
Below are the results for the Polyhedron 2005 benchmarks compiled with llvm/compiler-rt/dragonegg 3.3svn at r182439 against current FSF gcc 4.7.3svn and 4.8.1svn. The only major bug remaining in the dragonegg 3.3svn support for gcc 4.8.x is http://llvm.org/bugs/show_bug.cgi?id=15980 which results in unresolved symbols for _iround and _iroundf in the aermod and rnflow testcases.

Slow concurrent actions on the same LVM logical volume
Hi 2 all ! I have problems with concurrent filesystem actions on a ocfs2 filesystem which is mounted by 2 nodes. OS=RH5ES and OCFS2=1.2.6 F.e.: If I have a LV called testlv which is mounted on /mnt on both servers and I do a "dd if=/dev/zero of=/mnt/test.a bs=1024 count=1000000" on server 1 and do at the same time a du -hs /mnt/test.a it takes about 5 seconds for du -hs to execute: 270M

[plyr] Moving average filter with plyr
Dear all, I'm stuck with a problem using plyr to process a rather large junk of data.

estimating NA values against selected slots
Dear R Users, Could you please help me on the following issue? I have a real large yearly data set. For each year I have 365 flow values. Some of the flow values are not known and that’s why you will see NA written in those slots. I wanted to know, is there a way that I can estimate those values? I tried approx command but it seems least helpful for the kind of issue I am up against.

Some timings for 64 bit Opteron (ATLAS, GOTO, std)
Hi Martin, When I attended the LinuxWorld Expo in NYC back in January, I chatted with some folks at the AMD booth, as well as guys from Penguin Computing (where we bought our Opteron box). I was told that the Operton has this somewhat strange setup that the memory is controlled by one CPU. The net effect of this being that when both CPUs are running, one might only be running at around 90%
