I am using Anaconda to manage my R-installation. It works great for packages available in the R-channels provided by Anaconda, but I am having troubles installing packages not contained in the Anaconda repos.
I have tried a few different approaches, all listed below together with their error output.
1. install.packages('rafalib')
Suggested to work here conda - How to install R packages that are not available in "R-essentials"?. My .libPaths() points to '/home/user/anaconda2/lib/R/library'.
Out:
--- Please select a CRAN mirror for use in this session ---
Error in download.file(url, destfile = f, quiet = TRUE) :
unsupported URL scheme
Error: .onLoad failed in loadNamespace() for 'tcltk', details:
call: fun(libname, pkgname)
error: Can't find a usable init.tcl in the following directories:
/opt/anaconda1anaconda2anaconda3/lib/tcl8.5 ./lib/tcl8.5 ./lib/tcl8.5 ./library ./library ./tcl8.5.18/library ./tcl8.5.18/library
This probably means that Tcl wasn't installed properly.
I installed tcl from the conda channel r-old, but install.packages() still threw the same error message.
2. options(menu.graphics=FALSE) and then install.packages('rafalib')
I got a list of mirrors and chose one.
Out:
Selection: 15
trying URL 'http://cran.utstat.utoronto.ca/src/contrib/rafalib_1.0.0.tar.gz'
Content type 'application/x-gzip' length 11798 bytes (11 KB)

sh: symbol lookup error: sh: undefined symbol: rl_signal_event_hook
The downloaded source packages are in
‘/tmp/Rtmphwpta0/downloaded_packages’
Warning message:
In install.packages("rafalib") :
installation of package ‘rafalib’ had non-zero exit status
Both 2 and 3 are from Disable/suppress tcltk popup for CRAN mirror selection in R
3. Setting the mirror in ~/.Rprofile
Before trying install.packages(), I added the following to my ~/.Rprofile.
## Default repo
local({r <- getOption("repos");
r["CRAN"] <- "http://cran.us.r-project.org";
options(repos=r)})
Out:
trying URL 'http://cran.us.r-project.org/src/contrib/rafalib_1.0.0.tar.gz'
Content type 'application/x-gzip' length 11798 bytes (11 KB)
==================================================
downloaded 11 KB
sh: symbol lookup error: sh: undefined symbol: rl_signal_event_hook
The downloaded source packages are in
‘/tmp/RtmppIz9rT/downloaded_packages’
Warning message:
In install.packages("rafalib") :
installation of package ‘rafalib’ had non-zero exit status
4. Setting the download method to 'curl' or 'wget'.
While keeping the new ~/.Rprofile configuration. I guess this wasn't necessary since the package seems to be downloading fine now, but I tested it just in case.
Out:
sh: symbol lookup error: sh: undefined symbol: rl_signal_event_hook
Warning in download.packages(pkgs, destdir = tmpd, available = available, :
download of package ‘rafalib’ failed
Warning message:
In download.file(url, destfile, method, mode = "wb", ...) :
download had nonzero exit status
5. Manual download of rafalib
install.packages('../Downloads/rafalib_1.0.0.tar.gz', repos=NULL, type='source')
Out:
sh: symbol lookup error: sh: undefined symbol: rl_signal_event_hook
Warning message:
In install.packages("../Downloads/rafalib_1.0.0.tar.gz", repos = NULL, :
installation of package ‘../Downloads/rafalib_1.0.0.tar.gz’ had non-zero exit status
6. Building a conda package from rafalib
I opened a separate issue for this Errors building R-packages for conda. In short, it complains about missing dependencies that I already have installed. Update I got a round the dependency problem and I am now stuck at the same rl_signal_event_hook-error as for my other approaches.
7. sudo ln /usr/lib/libncursesw.so.6 /usr/lib/libncursesw.so.5
As per https://github.com/conda/conda/issues/1679, but it didn't fix the issue for me.
So it seems like I can now download the package fine, but installing it fails. I have seen the error message sh: symbol lookup error: sh: undefined symbol: rl_signal_event_hook previously when using R with irkernel in the Jupyter Notebook, but it has never obstructed my work. I have never seen anything relating to that error message when running python through anaconda.
I'm out of ideas. Does anyone know how I can install R-packages not provided by anaconda, such as rafalib or swirl?
I am on Linux (Antergos, an Arch derivative) with kernel 4.4.5-1-ARCH.
UPDATE 2016/04/15
There is some related discussion in this thread. I have tried to get around this error by installing different versions of ncurses, including this patched version, and I have tried to link the readline libraries, as suggested here, but I keep running into the same error. I'm quite lost at this point and any help to solve this would be greatly appreciated.
