Hi everyone, my apologies in advance if I'm overlooking something simple in this question. I am trying to use R's survey package to make a direct method age-adjustment to some complex survey data. I have played with postStratify, calibrate, rake, and simply multiplying the base weights by the correct proportions - nothing seems to hit the published numbers on the nose. I am trying to

We are constructing growth charts (age/weight and age/length) for children with diagnosis that impacts weight/length. But we we don't know how to use R for producing growth charts. We are collection data of Age, Weight and Length. The data are used to produce diagnosis-specific Growth charts (like the CDC Growth Charts:

Dear Ladies and Gentlemen, I have a fairly large database (N=13,000) and a single main categorical discriminator between the groups. I want to look at the time course of a number of continuous biochemical variables over chronologic age. Therefore I believe I need to prepare hexbinplots in two columns with simple regression lines in them (with useOuterStrips (in library(latticeExtra) if

hello, I am trying to do exploratory factor analysis with BRFSS dataset ( http://www.cdc.gov/brfss/technical_infodata/surveydata/2008.htm) for a couple of days, but I was not able to do that and got frustrated. Can anybody help me with step by step guide? BRFSS dataset provides ASCII or SAS format. Thank you. chloe [[alternative HTML version deleted]]

Hi, There: Clang fails to compile 254.gap @ CPU2000int suite. The symptom is that executable fail to run with reference input. The root cause is that the compiler mistakenly optimizes expr "x * y / y" into x where the x*y is blindly flagged with nsw without any analysis. The preproceeded code is excerpted bellow: cat -n integer.i --------------------------------- 2361

This has come up before, and we just added -fwrapv to work around the problem: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20110131/115969.html Are you compiling without -fwrapv?

Hey! I was wondering if active-HDL (VHDL simulator) will work with WINE 1.0? active-HDL (i regret to say) is only for windows.... :( Thanks :)

Hi, I'm trying to run Fisher's Exact test on the data below, but I'm not sure how interpret the data shown. Can someone tell me what this is saying? Looking at the numbers it should be that there's no significant difference between the HDL and LDL, but a p-value of 1 seems high. Is the low value in the LDL unbound making the test unstable and should I be using an alternative? Best

Dear there, I am working on the NHANES survey data, and want to apply quantile regression on these complex survey data. Does anyone know how to do this? Thank you in advance, Yiling Cheng Yiling J.

Hello All, I am still a beginner with R, and I only have a week or two under my belt so far. I'm working with NHANES anthropometric data on stature. I have two sets of data that have different statistical weights. I'm trying to combine those two data sets into one "mega-set" while retaining each data point's individual weight. If you have any idea as to how this is

Hi, I'm trying to connect an HDL F10 device for a friend living in Brazil to the TDM2400 on his Asterisk server. That device should behave like a normal doorbell and it is if connected to an analog PBX. I connected to the TDM2400 and everything works fine except for one thing: when the called party hangs up his phone, the F10 HDL device does not hang up. I'm not brazilian and not

Dear R users: I have a continuous outcome variable and four predictors, two continuous and two dichotomous. i would like to use the lattice plot to create scatter plots for the continuous predictors and boxplots for the dichotomous predictors. with 4 continuous variables, this is what i have been doing: trial = rbind ( cbind ( cimt$ant.mean, cimt$age, 1 ), cbind ( cimt$ant.mean, cimt$sbp, 2 ),

Hi, I have a need to process (in real-time) a large number of .sas7bdat files from within R. The problem is I don't want to convert these files to .xpt (transport) every time. So just checking if anyone has a (viable) way to read .sas7bdat files directly into R?

If you're designing a new high-level HDL, then it would be a good idea to familiarise yourself with the state of the art in this area (e.g. Bluespec System Verilog, Symbolics Processor Designer, and similar tools). Starting from comparisons to VHDL and Verilog is like designing a new high-level programming language today that is designed to be a better high-level programming language that is
