Installation Issue

[ClaraffD]

Hi all,
Please could Someone help me with the following DECoN related problems - Sorry I am such a newbie!

I installed R3.1.2 for macosx (snow leopard), and am having trouble installing DECoN, and other required packages.

When trying to use the setup.sh script in the Linux folder, the log file showed this error:

Warning in strptime(xx, f <- "%Y-%m-%d %H:%M:%OS", tz = tz) :
unknown timezone 'zone/tz/2021a.1.0/zoneinfo/Europe/Dublin'

  Calls: -> restoreImpl -> playActions -> installPkg
  Execution halted

I’m also finding it difficult to identify a good repository to link to when installing required packages. For example devtools, comes with the same error regardless of the repository I try:

Warning: unable to access index for repository https://cran.ma.imperial.ac.uk/bin/macosx/contrib/3.1
Warning message:
package ‘devtools’ is not available (for R version 3.1.2)

install.packages("devtools")
Warning: unable to access index for repository https://cran.ma.imperial.ac.uk/bin/macosx/contrib/3.1
Warning message:

Warning: unable to access index for repository https://cran.r-project.org/bin/macosx/contrib/3.1
Warning message:
package ‘devtools’ is not available (for R version 3.1.2)

Any help would be much appreciated! Thank you
