First of all I am so grateful for your advices and I am sorry for writting the
previous email using HTML instead of plain text.
I give forecast package as an example because is one of the packages that a I
need in my package, but the truly problem was months ago using FIAR package
because the condGranger() function was removed when it was updated and my
package needed this function. Anyway the problem was solved and now I decided
that the best option is use checkpoint() as Iñaki recomended.
Thank you so much again.
Andrea.

Asunto: Re: [R-pkg-devel] Problems installing dependences of my package
Hi Andrea,
If your code is highly dependent on a specific version, another option is to
include their code directly in your package. The forecast package is under
GPL-3 license, meaning you can use their code. You would just need include the
authors as a contributor
([ctb] tag) and make note of it in the relevant source code files and the
Copyright field in the description.

Hi,
I am writting because I am doing a package in R and I have some problems
installing dependences which appear at DESCRIPTION file.
First of all, I am not sure about the difference between Depends and Imports,
but I only use Depends.
My problem is that my package is going to be used at different computers and
for different persons so I want that when other person use my package, it can
be able to check if the necesary packages are installed and if they are not
installed, the package must
be able to install them.
I supposed that this problem was solved including the necesary packages and
their versions at “Depends”. And now, I have another problem because the
versions are usually indicated using “>=”, for example: forecast (>=8.7) but I
need to use exactly the versión
8.7 because sometimes when packages are updated, they lost some functions. But
if I use <= or == and the package is update to versión 8.8, my package
installation fail.
How can I solve this? If I use R normaly (outside my package), I can install
older versions of other packages using devtools::install_version() so why when
I indicate forecast (<=8.7) at Depends on the DESCRIPTION file, R is not able
to install an older version
if a new one is avaliable?
Thanks in advance for your attention.
Best regards,
Andrea.
