Help with response CIs for lme
Hi,
Can someone please offer a procedure for going from CIs produced by
intervals.lme() to fixed-effects response CIs.
Here's a simple example:
library(mlmRev)
library(nlme)
hsb.lme <- lme(mAch ~ minrty * sector, random = ~ 1 | cses, Hsb82)
(intervals(hsb.lme))
(hsb.new <- data.frame
minrty = rep(c('No', 'Yes'), 2),
sector = rep(c('Public', 'Catholic'), each = 2)))
cbind(hsb.new, predict(hsb.lme, hsb.new, level = 0))
Is the...

Slight discrepancy between predict.lm() and all.effects()
In the course of exploring response prediction, I stumbled upon a
small discrepancy between the CIs produced by predict.lm() and
all.effects()
require(mlmRev)

hsb.lm <- lm(mAch ~ minrty * sector, Hsb82)
hsb.new <- data.frame(
minrty = rep(c('No', 'Yes'), 2),

read.spss
...have loaded the foreign package and am still having problems with an import. I get a message that reads, unable to open file. Whe I try different files I get the same message. Here is the code I used. Am I missing something?
I am using 1.7 and have also tried this in 1.6 with the same problem.
hsb<-read.spss("C:\HLM504_Student\Examples\AppendxA\HSB1.SAV", use.value.labels=TRUE, to.data.frame=FALSE, max.value.labels=Inf)

Reading a TIFF file
...if the values obtained in R, times 255 would show the values obtained in ArcGIS, but this is not the case. The images are very different. I tried to settle matters using Photoshop, and the values there are completely different from the other two (using RGB, the K value (in CMYK) or the B value (in HSB))!!!
Can somebody help me with this problem? Can I trust "rtiff"? Should I stick to a very slow process in ArcGIS? Why PS, which should be the perfect measuring stick, is showing another set of values?
Thanks in advance. Regards.

Digital Image Processing
...se R to process digital images. There are several categories related to the general type of problem that are useful to know about:
-- Any existing packages for taking a digital image format {any flavor like TIFF, jpg, png, or GIF (or even TWAIN input)} and representing it internally in R as RGB or HSB arrays?
-- Any existing packages for taking array representations of an image and representing it "graphically" as a "bitmap" (colored?) image in an R window?
-- Any digital filter, image (signal) processing packages specifically directed at "image processing" or compu...

Drawing a colour wheel - bug in hcl?
Hi All,
I'm trying trying to draw a colour wheel (a slice of hcl space) in R.
Running the code below doesn't give me what I expect - there's some
oddly bright colours of the wrong hue around c(0, 0) and I see three
coloured circles (a small magenta, a medium sized yellow and a large
cyan). Am I doing something wrong or is there a bug in the hcl code?
(Also any suggestions for

Installing R-1.1.0 (PR#612)
Dear R-developers,
I finally got around to install R 1.1.0 but had problems at the `make
check' stage.
After compiling the released R 1.1.0 version the `make check' stage
stopped while checking the examples in base. There was some problem
with the quantile function and the check stopped complaining that NA's
are not allowed.
But I assume that this problem is already known because
