Error in if (n > 0)
I've searched the Web with Google and do not find what might cause this
particular error from an invocation of cenboxplot:

nested if/else very slow, more efficient ways?
Hello,
in the data.frame "resultsfuzzy" I would like to replace the
characters in the second column ("5a", "5b", ... "5e") with numbers
from 1 to 5. The data.frame has 39150 entries. I seems to work on
samples that are << nrow(resultsfuzzy) but it takes suspicously long.
Do you have any suggestions how to make the character replacing more

glm with negative binomial family
I am analysing parasite egg count data and am having trouble with glm with a
negative binomial family.
In my first data set, 55% of the 3000 cases have a zero count, and the
non-zero counts range from 94 to 145,781.
Eventually, I want to run bic.glm, so I need to be able to use glm(family=
neg.bin(theta)). But first I ran glm.nb to get an estimate of theta:
> hook.nb<- glm.nb(fh,

Repeated measures unbalanced in a split-split design
Hi,
I have a experiment with block, plots, sub-plots, and sub-sub-plots
with repeated measures and 3 factors (factorial design) when we have
been observed diameter (mm), high (cm) and leaves number (count).
However, we don't have one treatment in one factor, so, my design is
unbalanced.
On a previous message here, a friend tell me that "It appears to me
that your design is a split-split

Garch Warning
Dear all R-users,
I wanted to fit a Garch(1,1) model to a dataset by:
>garch1 = garch(na.omit(dat))
But I got a warning message while executing, which is:
>Warning message:
>NaNs produced in: sqrt(pred$e)
The garch parameters that I got are:
> garch1
Call:
garch(x = na.omit(dat))
Coefficient(s):

MANOVA: how do I read off within and between Sum-of-Squares info from the manova result?
Hi all,
I am experimenting the function "manova" in R.
I tried it on a few data sets, but I did not understand the result:
I used "summary(manova_result)"
and "summary(manova_result, test='Wilks')"
and they gave a bunch of numbers...
But I need the Sum-of-Squares of BETWEEN and WITHIN matrices...
How do I read off from the R's manova results?
Any
