Sobel's test for mediation and lme4/nlme
Hello, Any advice or pointers for implementing Sobel's test for mediation in 2-level model setting? For fitting the hierarchical models, I am using "lme4" but could also revert to "nlme" since it is a relatively simple varying intercept model and they yield identical estimates. I apologize for this is an R question with an embedded statistical question. I noticed that a

How to handle INT8 data
Hello r users, I have to deal with int8 data with R. AFAIK R does only handle int4 with `as.integer` function [1]. I wonder: 1. what is the better approach to handle int8 ? `as.character` ? `as.numeric` ? 2. is there any plan to handle int8 in the future ? As you might know, int4 is to small to deal with earth population right now. Thanks for you ideas, int8 eg: human_id

rimage package broken with fedora upgrade
Dear R list members I would be grateful if anyone could guide me to a solution for fixing my rimage package problem described below. I recently upgraded my machine from fedora core 3 to fedora core 6 and then upgraded R from version 2.3.1 from version 2.4.1. I then fired up R, tried to load the rimage library and received the following messages: > library(rimage) Error in dyn.load(x,

rimage doesn't install on Mac OS X 10.4
Hi, I'm trying to install rimage on a Mac OS X 10.4 machine. I followed the advice in previous R-help threads and got over the hurdles of having the header files in the right places, among other things. But I can't figure out what to do with this error. ice.pnl.gov:/home/waichler<949>system_profiler -detailLevel mini SPSoftwareDataType Software: System Software Overview:

I am having difficulty getting D2 w/ LOD 1.12 to run in colour through wine. I am running a ASUS eeepc 701 w/ the cpu running at 900mhtz and 2gb of ram.

How to handle INT8 data
Well I definitely cannot use them as numeric because join is the main reason of those identifiers. About int64 and bit64 packages, it's not a solution, because I am releasing a dataset for external users. I cannot ask them to install a package in order to exploit them. I have to be very carefull when releasing the data. If a user just use read.csv functions, they by default cast the

How to handle INT8 data
Right, they are identifiers. Storing them as String has drawbacks: - huge to store in memory - slow to process - huge to index (by eg data.table columns indexes) Why not storing them as numeric ?

Sybase ctlib Adapter
Hi, I''ve been trying to update Will Sobel''s sybase-ctlib adapter to pass unit tests on Rails 1.0. It''s been a slow, sloggy process for me so far, as I''ve been learning Ruby, Rails, and Sybase administration all in one go.

Altering the return address , for a function with multiple return paths
Playing around with calling conventions naked functions and epilogue/prologue... Is it possible/expressible/feasible to alter the return address the function will return to? For example, when a function may return an Int8 or a Float64, depending on some external state (user, or random variable), instead of checking the returned type in the calling function, is it possible to pass 2 potential

How to handle INT8 data
Hi, I do have < INT_MAX. This looks attractive but since they are unique identifiers, storing them as factor will be likely to be counter-productive. (a string version + an int32 for each) I was looking to https://cran.r-project.org/web/packages/csvread/index.html This looks like a good feet for my needs. Any chances such an external package for int64 would be integrated in core ? Le 20

problem with lattice tiff or bitmap: character size and color
Hi all, I am trying to make tiff files of lattice plots at a resolution greater than 300 dpi required by a journal (PLoS ONE). I have tried both the tiff and bitmap functions. tiff keeps panel colors but reduces axes and tick labels so they are nearly invisible. bitmap maintains correct label size but only produces greyscale. Regular plots work fine with tiff; the problem is only with lattice

A different take at video encoding - I'm stuck though
As I said in the other thread (for people using threaded mail)/in my last mail (for the rest), I'm working on the "split up the frames into textured triangles and output textures and coordinates" idea. The idea is to find edges in the image. So far I have a Sobel edge detector, a wavelet transformer (to compress the textures, still very incomplete, transform only), and some

[LLVMdev] Why BinaryOperator::Create requires same argument types for shifts?

In my case, original types were uint8 (value) and uint32 (shift) llvm lacks unsigned types which made it S1=i8 and S2=i32. It's technically nothing wrong with such combination, and code works

change colour of geom_step by scale_colour_manual
Hi, Color of my step plot is now by default. Now I'd like to change the color as the grey scale I specified. I don't know why I got three black plot. Here I attach two version of codes. The first one produces a step plot with color by default. The second one, modified from the first one, is not producing the grey scale I want. Any help would be highly appreciated.

[LLVMdev] Operations on constant array value?
Hi, I've read http://llvm.org/docs/LangRef.html#t_array and http://llvm.org/docs/GetElementPtr.html and if I've understood right there are no operations that act directly on arrays - instead I need to use getelementptr on a pointer to an array to get a pointer to an array element. I also understand that there is no 'address of' operation. As a result I can't figure out how to
