Physical Units in Calculations
Back in 2005 I had been doing most of my work in Mathcad for over 10 years. For a number of reasons I decided to switch over to R. After much effort and help from you folks I am finally "thinking" in R rather than thinking in Mathcad and trying to translating to R. Anyway, the only task I still use Mathcad for is calculations that involve physical quantities and units. For example, in

missing ctest and methodological question
...ific advice. For a publication a have to check about 80 samples with about 3000-5000 values each whether they a normally distributed (N(0,1) to be exact). The problem is, that they are derived from discrete measurements (the weight of children, for example, where nearly all values have full or half kilograms), so Kolmogorov-Smirnov doesn't seem to be the right choice. Shapiro-Wilk, however, is limites to 5000 values, for good reasons, I think. Personally, for a single sample I would make some plots for everyone to see that it fits quite good, but in this case it would be nice if I could finally ha...

Adjusting for heaping in data
Hi R users. I am new to the community and have got myself into a little problem. I have a dataset of birth weights recorded by nurses at a delivery clinic in an developing country. The weights are entered in KiloGrams with one decimal. However there is substantial heaping at each 500g when looking at the sample in a histogram. Do anyone of you know a easy way to adjust for this and if it exists an R package to implement the method? Best regards Thomas Fr?jd

Need to fit a regression line using orthogonal residuals
I'm trying to fit a simple linear regression of just Y ~ X, but both X and Y are noisy. Thus instead of fitting a standard linear model minimizing vertical residuals, I would like to minimize orthogonal/perpendicular residuals. I have tried searching the R-packages, but have not found anything that seems suitable. I'm not sure what these types of residuals are typically called

Patch rejections against 2.4.11pre2
...pre2, but I need ext3; and the 0.9.10 patch that works on 2.4.10 has two non-trivial rejections in fs/buffer.c. Has anyone successfully integrated ext3 with 2.4.11pre2? -- Chip Salzenberg - a.k.a. - <chip@pobox.com> "We have no fuel on board, plus or minus 8 kilograms." -- NEAR tech

Please help me interpret these results (fitting distributions to real data)
I just thought of a useful metaphore for the problem I face. I am dealing with a problem in business finance, with two kinds of related events. However, imagine you have a known amount of carbon (so many kilograms), but you do not know what fraction is C14 (and thus radioactive). Only the C14 will give decay events (and once that event has occurred, the atom that decayed will never decay again). C12 will never decay. What you want to know is a) what is the ratio of C12 to C14 at time 0, and b) how many de...

offset in gam and spatial scale of variables
Hi, We are analizing the relationship between the abundance of groupers in line transects and some variables. We are using the quasipoisson distribution. Do we need to include the length of the transects as an offset if they all have the same length?? Also, can we include in the gam models variables that are measured at different spatial scales? We have done an analysis to see what variables
