Comparing vectors from lists
Hi guys,
I still did not solve my problem properly! I have to compare the values of two lists of 250 numbers as a result of using the ?by function!
List1 of 250
$ 0 : num [1:28] 22 11 31...
$ 1 : num [1:15] 12 14 9 ...
..
..
..
- attr(*, "dim")= int 250
- attr(*, "dimnames")=List of 1
List2 of 250
$ 0 : num [1:24] 20 12 22...
$ 1 : num [1:17] 11 12 19 ...

Looping over groups
Hello,
My R skills are somewhere between novice and intermediary, and I am hoping that some of you very helpful forum members, whom I've seen work your magic on other peoples' problems/questions, can help me here.
I have a matrix with the following format:

Tukey HSD following lme
Hi everyone
I'm using Tukey HSD as post-hoc test following a lme analysis. I'm
measuring hemicelluloses in different species treated with three
different CO2 concentrations (l=low, m=medium, h=high). The whole
experiment is a split-plot design and the Tukey-function from the
package multcomp is suitable for lme-analysis with random factors.
The analysis works fine but I get a non

Subsetting dataframes
Dear all!

I am working with an ongoing malting barley variety evaluation within
Sweden. The structure is 25 cultivars tested each year at four sites, in
field trials with three replicates and 'lattice' structure (the replicates
are divided into five sub blocks in a structured way). As we are normally
keeping around 15 varieties from each year to the next, and take in 10 new

export to text file
I'm trying to export a large data frame to a text file for permanent

didn't work. Any suggestions?

tdm400p not working with brazilian lines
Hi,
I'm installing an Asterisk box with a TDM2400P in Brazil. I can make
analog phones work while lines are not working. Since I do not know

wrong/missing in my conf files (below)?

Strange Problem with "proj" and "aov" for split-plot analysis output
I'm using R 1.8.1 on Red Hat Linux 9. I've worked out the linear model
decomposition by hand. Using "aov" with "Error" to fit a split-plot
model, I get very different results depending on whether I use the
"data" argument for "aov" or not. When I use the "data" argument, the
ANOVA table from "summary" is correct but the

Sending DTMF to PSTN problem with SIP
Dear All ~
I have * setup & running ok (with two Wildcard X100P's to PSTN). I also have
two analog phones connected into same through a SIPURA 2000. These work fine,
except that when I call out through PSTN & try to send DTMF tones to (say) a
remote PBX to dial an extension, the gain seems to go wild (high), and the
DTMF tones are not recognized at the other end.

How to return individual equation from {aidsEst} in package [micEcon]?
Hi, R core team
I am using the function {aidsEst} in package [micEcon] to do an AIDS
model now. So far, everything is good. But I want to test the auto
correlation and heteroskedasticity of the individual equation from AIDS
demand system. How can I return the individual equation?
PS: serial correlation test is {bgtest} in package [lmtest] and
heteroskedasticity is {bptest} in package

rsync transfer efficiency
Hi,
Does anyone have the data of the rsync transfer speed vs. other tools like ftp?
Or where is the place to find such information that compare the transfer speed
between different tools?
If I were to transfer a single large file, say 500Mega Byte, previously
non-existent on the remote host, what would be the fastest tool I can choose for
transfer?
Thanks,

iterative output to file by row
Hi,
I'm sort of a newbie to using R to deal with array data. I'm trying to
create a simple filtering function, which outputs only the rows of a
data frame that satisfies a specific criterion. I've set up an
iterative loop to apply the condition to each row. I can create a new
matrix and use rbind to fill it in row by row in the loop, before
writing the whole matrix to file. But

Cointegration and ECM in Package {urca}
Dear R Core Team,
I am using package {urca} to do cointegration and estimate ECM model,
but I have the following two problems:

cointegration rank, alpha and beta. The next step is to test some
restrictions on beta with blrtest(),bh5lrtest(), and bh6lrtest(). But
none of them can add restrictions on all the cointegration
