Should you be using rsiTA(tsx[,2],14). If you look at the function you will see
it is expecting just the values you want in the calculation.

Dear R-user,
I have a data like this below,
age <- c("young","mid","old")
married <- c("no","yes")
income<- c("low","high","medium")
gender<- c("female","male")
I want to make some of combination data like these,
age.income.dat <- expand.grid(age, married[-c(2)], income

in the specific example you could consider something like this:
test <- array(c(1:16), dim = c(3,4,3))
##
test.ind <- rbind(c(2,4,1), c(2,4,2), c(2,4,3))
test[test.ind]
test[2,4,]
I hope it helps.
Best,

Hi
I have measured the UV absorbance (abs) of 10 solutions of a substance at
known concentrations (conc) and have used a linear model to plot a
calibration graph with confidence limits. I now want to predict the
concentration of solutions with UV absorbance results given in the new.abs

Is the fixed effect estimated at the innermost level? If not,
plots of residuals at that level are surely of limited interest.
qqplots, to be relevant, surely need to assess normality of
effects (rather than residuals) at the level that matters for
the intended inferences.

Dear all,
when performing a meta analysis I have two results obtained with logLik
and lme, which I do not quite understand.
The results are based on these data:

As a first shot, use lm with a matrix response. That fits them all at once
with one QR-decomposition. No analogue for glm or lmer, though, since for
those the iterative fits run do depend on the response.
Thanks Brian, that's very helpful. Also thanks to Kevin Wright who

Prof Brian Ripley,
I found the error by chance. the error is found in R2.1.0 too.
As far as I can see, if anyone had run any example() in R on a Windows
machine in your locale it would have failed. But no one reported a
problem. I don't even have that local
Look at "?Comparison", especially in the "Note" section:

For numerical values, remember == and != do not allow for the finite
representation of fractions, nor for rounding error. Using all.equal
with identical is almost always preferable. See the examples.
