hi: maybe it's minimizing the negative of the likeihood rather than
maximizing the likelihood ?
other than that, i don't see that being possible because of what you
said. see what
happens if you estimate an arima(1,1,3) ?

Henrik,
Ah, I did briefly search the list archive, but hadn't come across your
earlier post, sorry.
I can confirm the conditions you outlined back then (ie. it's L-ALT+TAB, and
only that, that causes the problem, that on return to rterm I can use ctrl-C
to interrupt a running R call but then no
Hi,
I have this very simple two-line script :
test.r:
print (abc);
write(def,test.txt);
When run with rscript.exe --vanilla test.r (or just rscript.exe test.r), I
get the abc output in the shell but no file is created in the
directory
I noticed that the only time the test.txt
OK,
obviously that was a silly question...
SOLUTION: just specify the path in the write function...!
Sorry !

Hi all,
I have data from an experiment with 3 independent variables, 2 are
within and 1 is between. In addition to the dependent variable, I have
a covariate that is a single measure per subject. Below I provide an

Need help with graphics. I am runnig a simple lm and then using
allEffects from 'effects' package:
require(effects)
model-lm(Y~A+B, data=mydataframe)
I am trying to build (for each predictor - A and then B) a plot of means on Y.
I was successful doing it like this - in one swoop:

In the biomedical arena, at least as I learned from Rosner's
introductory text, the usual approach to analyzing paired 2 x 2 tables
is McNemar's test.
?mcnemar.test
mcnemar.test(matrix(c(73,0,61,12),2,2))
McNemar's Chi-squared test with continuity correction
data: matrix(c(73,
I have a problem with ifelse(), I do not understand how it works.
X-c(2,2,1,1,0,0)
str(X)
num [1:6] 2 2 1 1 0 0
Y-ifelse(X0,1,0)
Y
[1] 1 1 1 1 0 0
Can some one explain what is going on, I do not understand what ifelse is
doing in this case. Can someone explain the output Y.
Thanks

Dear Colleagues,
When I try to install Rcmdr the following happens:
--
library(Rcmdr)
Error in structure(.External(dotTclObjv, objv, PACKAGE = tcltk), class =
tclObj) :
[tcl] invalid command name font.

Error:
It is checking the series of values of X and returning a series of 1
and 0's;
1 if it meets your condition (X0) and
0 if it doesn't.
What did you expect?
A more complex invocation might look like this:
ifelse( X 0, 1:3, -1:-2)
[1] 1 2 3 1 -1 -2
Note the recycling of the elements
Hello,
ifelse checks condition whether X (or, ina fact every value in X) is greater
than 0. If it is 1 is assigned and if it isn't then 0.
2 and 1 are greater than 0, therefore the first four values of Y are 1. 0
isn't greater than 0, therefore the last two values of Y are 0.
