Multiple ANOVA tests
Hello!!!
I'm trying to do multiple ANOVA tests with R (testing the affect off
different factors on the same response). As a result I get many ANOVA
tables, and I want to extract a list of the "Pr(>F)" from all the tables.
Maybe someone have an idea how to do this?
Thanks

Newbie question on Rsync on Solaris
I want to replicate between two Solaris hosts. The source is Solaris 2.6
and the target is Solaris 2.8. Using rsh, the basic program seems fine (not
running in daemon mode), but I have a problem.
The directory tree is about 150,000 files, with about 5 gb of data. I
tar'd the directory and moved it to the other side, but when I run an rsync
against that directory, it still wants to move

Confidence intervals of quantiles
Can anyone please tell me if there is a function to calculate confidence
intervals for the results of the quantile function.
Some of my data is normally distributed but some is also a squewed
distribution or a capped normal distribution. Some of the data sets contain
about 700 values whereas others are smaller with about 100-150 values, so I
would like to see how the confidence intervals change

Can someone explain this error below,

I have 4 years of data and for each year, I have initialize the value so now for fitting the model, I want to remove the initial value and get the model based on remaining data set. Could anyone can help on this?
I want to get linear model based on fourth column and 13th column but need to remove the initial value for each year and each treatment ( the second column I have 1:36) .
Thank you,

Open channels
First, I'm not sure is this Asterisk or ooh323 channel problem.
It seams that I have solved (I do hope so!) deadlock problem with ooh323 (thanks to Sean and his patch). Now I have another one. It seams that some channels stay open even they should not. This is what I see from CLI:

remove rows of a matrix by part of its row name
Hello,
Please always cc the list.
As for the question, yes, it does. If you want to remove just the ones
with exactly 73.1 use the pattern
grep("^73\\.1$", etc)
Explanation:
Beginning of string: ^
End of string: $
Escape special characters: \\ (needed because the period is a special
character.)
Hope this helps,

dsync verbosity, summary of transfer
Hi!
I am playing with dsync and trying to fix an issue I have mentioned in
another thread (subject: "Re: [Dovecot] Dsync error: Couldn't drop
privileges: getgrnam") and feel that dsync could use some additional
informational output. It would be particularly helpful while
experimenting with a migration if it could output a transfer summary and
/ or log separately.

length 1 offset in glm
Hi,
I'm trying to use an offset with glm. According to the glm man
page
offset ... This should be NULL or a numeric vector of length either
one or equal to the number of cases. ...
but with the following example, I get an error if the offset is of length 1
c1 <- structure(list(Contr = c(0.028, 0.043, 0.064, 0.097, 0.146, 0.219
+ ), Correct = c(34L, 57L, 94L, 152L, 160L, 160L),

Error in `[[<-.data.frame`(`*tmp*`, alt.name, value = integer(0)) with mlogit
I don't know either. Perhaps someone else on the list who uses that _contributed_ package will know.
Please be aware that it is both possible and preferred that you make reproducible examples so others can troubleshoot. See any of [1][2][3]

Error in `[[<-.data.frame`(`*tmp*`, alt.name, value = integer(0)) with mlogit
Hello,
There's a typo in your call to mlogit.data, it should be
alt.var="nbChev", not alt.var="noChev".
Then the error is different. You should check the call arguments to see
if they make sense.
Hope this helps,

Error in `row.names<-.data.frame`(`*tmp*`, value = c("1.9", "1.9", "1.9", : duplicate 'row.names' are not allowed
Hi
I did not notice any answer to your question so I try. After studying docs and other responses to similar question I deduct that chid.var and alt.var are mixed together and new data frame is being build with chid.var and alt.var combination as new row names. As the combination is not unique this operation results to error.
But I may be completely wrong.
Cheers
