Two apparent bugs in aov(y~ *** -1 + Error(***)), with suggested (PR#6510)
I think there are two bugs in aov() that shows up when the right hand
side of `formula' contains both `-1' and an Error() term, e.g.,
aov(y ~ a + b - 1 + Error(c), ...). Without `-1' or `Error()' there
is no problem. I've included and example, and the source of aov()
with suggested fixes below.
The first bug (labeled BUG 1 below) creates an extra, empty stratum

Two apparent bugs in aov(y~ *** -1 + Error(***)), with (PR#6520)
I believe you are right, but can you please explain why anyone would want
to fit this model? It differs only in the coding from
aov(y ~ a + b + Error(c), data=test.df)
and merely lumps together the top two strata.
There is a much simpler fix: in the line
if(intercept) nmstrata <- c("(Intercept)", nmstrata)
remove the condition (and drop the empty stratum later if you

possible bug in aov?
Hi, I'm interested in doing a repeated measures anova using aov. The procedure is nicely described in section 6.7.1, pp. 24-27 of Baron and Li's "Notes on the use of R for psychology experiments and
questionnaires," and I've reproduced their example exactly.
My own problem is almost identical to theirs:

Image analysis in R?
As far as I can tell, there are no facilities in the "base" R for image
analysis. Is there any extension or package for R that implements
image analysis? I'm thinking of features such as
o Reading and writing image files,
o displaying indexed or "true color" images,
o resizing, cropping, etc, of images,
o filters for manipulating images (smoothing, edge detection, etc)

Referencing R in journal paper?
I'm using R for calculations and plots in a statistical paper. Is
there a canonical reference to use in the bibliography? (Or is it not
common to acknowledge computer programs in journal papers?)

Error in "names<-.default"(`*tmp*`, value = nmstrata) :
Hi,
I have a problem with aov(). I used it many times, but now I have new data,
tried to use it in the same way. I get I strange Error message that i can't
understand (see below). I guess it is caused by incompatible data types. The
dataframe also looks ok to me.

Actually, we'll be discussing tools to make packages in general that can work
in both S-PLUS and R, and also how to make some S-PLUS-only libraries
available in an open-source environment as well as working with package
authors to port R packages to work in

FW: sapply to return factors in dataframe
Ahhrg List,
there was a hitch in the previous code. Updated and functional version
follows after my initial question:
I am trying to randomise a dataframe with mixed factors/numeric
variables and return a new (randomised) dataframe with the same columns
(as factors/numeric).
simgap<-function(x) {
ma<-max(x)
mi<-min(x)
Xout<-runif(length(x),min=mi,max=ma)

mode data=journal in ext3. Is it safe to use?
Hello
I try again.
Can anybody of you acknowledge or not if mode data=journal in ext3 is
safe to use in Linux kernel 2.6.x?
Wee need to have a very consistent and integrity for our filesystem, and
it would then be desired to journal both data and metadata.
But if this mode can corrupt the filesystem as both Phil White and
Nicolas Kowalski has experienced, it may be more advised to use mode

Calling fft from C
Hi
I have made a R function 'convolve2' for convolution of two real
valued vectors based on Rs 'convolve' with option type="open" - see
below.
(exp.length and irf.length are variables set in another part of the program)
I wish to implement the function convolve2 in C and use it in a
function used from R with .Call - e.g. I need to call fft in C.

Re: Sid Meier´s Alpha Centauri
Looks like I can't edit posts.
Also of possible interest, I was using v1.0 of the unofficial patch by scient, available here (http://www.weplayciv.com/forums/downloads.php?do=file&id=240). However, I don't suspect that made a difference. If I get round to more thorough testing I'll add a version and some more notes to the appDB.
Comments welcome.

Unweighted meta-analysis
Hello
I'm very much a beginner on meta-analysis, so apologies if this is a
trivial posting. I've been sent a set data from separate experimental
studies, Treatment and Control, but no measure of the variance of effect
sizes, numbers of replicates etc. Instead, for each study, all I have
is the mean value for the treatment and control (but not the SD). As
far as I can tell, this forces
