Hi -- there are lots of replies --I have not read them all, if someone else
suggested this, sorry for duplication. This is similar to the suggestion using
mapply, but not specific to matrices. In fact it's a kludge that applies to
many settings. You 'sapply' over the index 1:2, and pass a, b as
Could someone explain what is happening with the ...() of the
following function:
dots <- function(...) as.list(substitute(...()))
I understand what I'm getting as a result but not why. ?dots and
?substitute leave me none the wiser.

You need to understand what substitute() does -- see ?substitute and/or a
tutorial on "R computing on the language" or similar.
Here is a simple example that may clarify:
> dots <- function(...) as.list(substitute(...()))
> dots(log(foo))
[[1]]
log(foo) ## a call, a language object
> dots2 <-
Always hard to tell if THIS is a homework project. As with most things in R,
if you can not find at least a dozen ways to do it, it is not worth doing.
The question (way below) was how to take two vectors of length two and make

Hello everyone!
I am currently working with a time series panel data set measuring six
dependent variables:
4 of which are binary and 2 of which are count data.
I am interested in constructing a model to measure if the dependent variables
influence one another.
For example: DV1~ DV2 +

Hi Mir,
Without knowing what the data looks like, this is only a guess.
read.table() expects a white space delimiter and if you have a space
in one of your column names it will consider it as two names instead
of one. How many columns do you expect?

Hi,
You can try this.
Example: 1
a <- c(1, 4)
b <- c(5, 8)
unlist(as.vector(mapply(seq,a,b)))
> [1] 1 2 3 4 5 4 5 6 7 8
a <- c(1, 4, 2)
b <- c(5, 8, 10)
unlist(as.vector(mapply(seq,a,b)))
> [1] 1 2 3 4 5 4 5 6 7 8 2 3 4 5 6 7 8 9 10
Regards.

Then you'd rather need
install.packages("aod",repos='https://cran-archive.r-project.org')
or use the contrib.url argument.

Thanks for the help. I do update to the latest R-4.0.2. As I said, for
reasons that's hard to explain, some of my tasks are better handled with
an older version of R, in this case R-3.0.3. Please just help me install
packages successfully with this older version of R.
I ran the following line

Thanks. I did as suggested but still received a warning, though the
installation went through. Anything I could do to install without the
warning message.
What is the contrib.url argument?
