Can be as short as:
condense <- function(x)
unname(tapply(x, c(0, cumsum(diff(x) != 1)), FUN = function(y)
paste(unique(range(y)), collapse = "-")
))
z <- c(1

Dennis,
You are supposedly using a vector containing integers, in order, and want to
find sequences to rewrite compactly based on your example.
What result do you want. An integer vector cannot hold something like 3-5 so
do you want an integer of character stringls like this:
c("1", "3-5", "7-8"
Hi Dennis,
A quick Claude request:
"using r I have a sequence like:1, 3, 4, 5, 7, 8, 12, 13, 14, 15,
20I would like to display it as:1, 3-5, 7-8, 12-15, 20"
yielded:
condense_sequence <- function(nums) {
if (length(nums) == 0) return("")
if (length(nums) == 1) return(as.char
Cute exercise!
"Simple" is in the eyes of the beholder, of course. There is probably a
package out there that can do this in a trice .
But my first thought -- so caveat emptor!, as my thoughts, first or last,
are often not so, um... thoughtful -- is to diff() the sequence (as
numerics) -- so that

I have a sequence like:
1, 3, 4, 5, 7, 8, 12, 13, 14, 15, 20
I would like to display it as:
1, 3-5, 7-8, 12-15, 20
Any simple ways to accomplish this?

It sounds like your first course of action should be to contact the package
maintainer. See ?maintainer or consult the Description file for the package
for their email.

More specifically, there is an issues list for the package here:
https://github.com/nk027/bvar/issues (I got there by looking at the
BugReports: field in the package description at
https://CRAN.R-project.org/package=BVAR )

Hi,
I am working on a modelling project for Brazilian inflation, for which I am
tempted to use the BVAR package in R. I read the paper and the documentation
and yet I could not find any further information on how the values of the
