Bash/tcsh and missing R packages when installing AFNI

AFNI Message Board
1

Good weekend, everyone,

Thank you in advance, my dear in the AFNI community,
I am new to AFNI and can not figure out what’s going on when installing AFNI.

errors come out as follows (also see attached file please),

  1. installing the R

Hi, Shun-

It is hard to say without knowing more about what operating system you are using.

What is your output of:


afni_system_check.py -check_all

?

I believe that version of R is not modern enough, but please copy+paste the output of the above command.

Hi, Shun-

Thanks for sending that. I think that, indeed, you just need to update your R version. To do that in this case, you should be able to do the following

---- EDIT: well, actually wait, this appears to not have sorted things; watch this space for a better answer hopefully shortly… ---------

Shun, the installation failure of ‘brms’ is most likely due to an old version of R. Update your R and then run

rPkgsInstall -pkgs ‘brms’

Hi, Shun-

I believe that you should first remove R, because otherwise there are version conflicts. Then,

  1. open the “list” file of sources for your package manager (sudo/admin password required):

sudo gedit /etc/apt/sources.list
  1. Copy+paste this line to the bottom of that file (this gives your package manager a new place to look for files to install- specifically, R v3.5 on Ubuntu 18.04; for other people people doing this on different versions of ubuntu, instead of “bionic” one might have “xenial” (for Ubuntu 16.04) for example, whatever the fun Ubuntu name for your exact LTS version is):

deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/

You can save+close that file now.

  1. Refresh the list of packages that your package manager reads-- copy+paste this:

sudo apt-get update
  1. Now instruct your package manager to update its R base installation (this should get 3.5 now)-- copy+paste:

sudo apt-get install -y r-base-dev r-cran-rmpi
  1. Use the AFNI command to get necessary packages, which should now include brms-- copy+paste this:

rPkgsInstall -pkgs ALL

Note, this step miiiiight take a little while, to fully build the R package.

Run the afni_system_check again, and let us know if that sorts out your R issue.

Good morning, Pt

Sorry for the late response.
Error information come out When I uninstall the R.

  1. Here is the source list (the last several commands )
    [i]## Uncomment the following two lines to add software from Canonical’s

‘partner’ repository.

respective vendors as a service to Ubuntu users.

  1. Here is the error information.

Do you know what’s going on with this?
It seems that the last command is something wrong

Thank you very much!

Hi,

I think there should be a space between “ubuntu” and bionic-cran35 in the uncommented deb line; unfortunately, this interface turns links into abbreviations, but it should look like the following with the underscores “_” removed:


deb h_t_t_p_s_:_/_/cloud.r-project.org/bin/linux/ubuntu bionic-cran35

Try copy+pasting that and replacing the current link (or adding the space there).

Hi-

I am sorry, but I’m not sure. I’ve tried it on my system, and things worked.

I removed R with:


sudo apt-get remove r-base-core

Then, this is what the end of my /etc/apt/sources.list file looks like, if that is useful (though, note that this forum format will change the full links to the abbreviations, that you will have to see by clicking on them):

deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/

After that, I ran:


sudo apt-get update

so the manager could see the changes.

Then:


sudo apt-get install -y r-base-dev

to install R, which should be some v3.5.* now.

Then,


rPkgsInstall -pkgs ALL

… and that updated the new packages.

Thank you very much, PT,

You are very helpful.
I rarely saw that a scientist replied questions more speedy than you on any forums!
It must be something wrong with my PC, but I can not figure out what’s going on so far.
However, when I installed the R --version 3.4.4, it worked…

But, another piece of information come out showing as follows,


=========================  summary, please fix:  =========================
*  login shell 'bash', trusting user to translate code examples from 'tcsh'

Thank you, pt

Hi, Shun-

Hmm, OK, well if you have got the R packages installed, then that’s great.

If you are also asking about that message/notice at the bottom of the afni_system_check.py output, then:
It’s not something that requires you to do anything. It refers to the fact that many times when we reply to questions on the MB or put examples online, we use “tcsh” shell syntax defining variables, loops, etc. There is no very deep reason for using tcsh over bash, I don’t believe, other than tcsh appears to be a bit easier to read directly and not have some quirks like being strict about whitespace usage.

Most times, people tend to put those code snippets into scripts, anyways, so it’s really not a big deal. It’s just a notice of that fact. Using bash in your terminal is fine.
