code is from an example provided in the mlogit documentation:
library(mlogit)
data(Train, package=mlogit)
tr-mlogit.data(Train, shape=wide, choice=choice, varying=4:11,
sep=, alt.levels=c(1,2), id=id)
Yes,Ii did fail to read your post carefully and agree do.call seems
roundabout, but alternatives look even more tortured.
(You might want to include more context in the future.)

Plot doesn't create an object to be plotted later like in ggplot: rather it, by
default, makes a new plot and erases the histogram.
hist(z)
lines(z, y, lwd = 1)
should work, though you may need to add freq=FALSE to hist()

The print method is the issue:
t.out - t.test(b1,b2,var.equal=T)
t.out$p.value
[1] 4.108001e-38
t.out$statistic
t

Here's a hack, but perhaps you might want to rethink what type of
output you want.

Leaving the indices empty should give you what I'm guessing you want/expect.
x[,,2]#. TRUE would also work, just not in a list.
Exactly, but this only works if x has three dimensions. What I want is
x[,,2] if x has three dimensions, x[,,,2] if it
Hi,
I use the epicalc package which provides the function aggregate.numeric.
Unfortunately aggregate.numeric produces warnings when aggregate is used by
functions not under my control on a numeric value. If I don't load epicalc,
aggregate.default is used instead by these functions and does not

Sorry for not stating my problem in a more clear way. What I want is,
given an array of n dimensions, overwrite it by iteratating over its
outermost dimension... OK, in the previous example, I would like
to do
x- array(NA, c(2,2,2))
for (i in 1:2)
Dear R People:
I have a variable named file1 which contains the name of a file. I
would like to copy that file to a different directory. Can I do that
via the system command or is there a better way, please?
Thanks,

You *might* want to consider using file.rename() rather than
system(). Dunno what the pro's and con's might be.
Still have to use paste(), but! :-)

I'm somewhat confused on how you intend to use browser() after
rerouting output to a sink
Beyond that, how are you running your script? source() has some
arguments that encourage it to say alot more to the sink() command.
