Error ".onLoad failed in loadNamespace() for 'tcltk'"
Solution 1
tcltk
is not a typical package. It's probably already installed on your system and it cannot be installed using the usual install.packages
procedure because it is not on CRAN (just like the base packages that come with R, like stats
, etc.). Also, tcltk2
is not the same as tcltk
; that is a package that expands upon (and depends on) the functionality of tcltk
.
So, start with this:
> capabilities("tcltk")
tcltk
TRUE
If that comes back FALSE
it means that your R was not built with tcltk support. You don't say what OS you're using, so it's a little bit difficult to help you.
That said, if you're on Linux, you need to rebuild R with tcltk support. This should be relatively straightforward. Basically, make sure Tcl and tk are available on your system in a standard location (something like sudo apt-get install tcl8.5-dev tk8.5-dev
) and then rebuild R per usual procedures.
If you're on Mac OS, you're encountering the same error that John Fox describes here in relation to Rcmdr. In short, it's probably one of two things:
-
A file permission issue related to the directory where you have Tcl installed. To quote Fox: "You can verify the source of this problem by issuing the following command at the R command prompt:
system("ls -ld /usr/local /usr/local/lib /usr/local/lib/libtcl*") # ls: /usr/local/lib: Permission denied # ls: /usr/local/lib/libtcl*: Permission denied # drwx------ 8 root wheel 272 Sep 24 10:21 /usr/local
If the output of the system command looks like the above, you should go to Terminal and do the following: sudo chmod -R a+rX /usr/local
and enter your password to change directory permissions.
- You have an out-dated version of X-Windows. Try running Mac OS Software Update.
It may also be solvable by creating a symbolic link as described in this answer.
This should never come up on Windows, unless you built R from source without tcl/tk support.
Solution 2
The official installation instructions for R say:
Note: the use of X11 (including tcltk) requires XQuartz to be installed since it is no longer part of OS X. Always re-install XQuartz when upgrading your OS X to a new major version.
So: Simply (re)install XQuartz if you want to use the tcltk
package in R.
Solution 3
- delete the X11 file on location : /opt
- delete the X11 on application unitiltiy
- reinstall X11 again
Problem solved...
Solution 4
On Arch Linux, tk
is a separate package from tcl
and both need to be installed:
sudo pacman -S tcl tk
This is given that the output from capabilities("tcltk")
with R is TRUE
(which means your R is compiled with tcltk
support as noted previously in the answers here, this should be the case if you installed it from the arch repos).
Solution 5
I had the same issue and went down a rabbit hole before discovering a simple fix. If you install R from bianry it will include tcltk by default. Just run the installer with the default installation. You can get the .dmg here: https://cran.r-project.org/bin/macosx/

I have a general question about how to effectively load any kind of external package into R. I have found that many sources detailing this information are simply insufficient, but I will leave out mentioning those respective URLs. I have successfully loaded external packages into R before, but I am having difficulties loading the
fgui
package.In my specific case, I cannot load the library
fgui
into R Studio. First I download directly from CRAN with the command:install.packages("fgui", lib="~/Documents/R_dir")
This works fine for me. My working directory is set to ~/Documents/R_dir
The next command I use is:
library("fgui", lib.loc="~/Documents/R_dir")
The error I get is:
Error : .onLoad failed in loadNamespace() for 'tcltk', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.1/Resources/library/tcltk/libs/tcltk.so': dlopen(/Library/Frameworks/R.framework/Versions/3.1/Resources/library/tcltk/libs/tcltk.so, 10): Library not loaded: /opt/X11/lib/libX11.6.dylib Referenced from: /Library/Frameworks/R.framework/Versions/3.1/Resources/library/tcltk/libs/tcltk.so Reason: image not found Error: package or namespace load failed for ‘fgui’
I have examined the thread "Error when trying to load library(ggplot2) in R" but it did not answer my question.
Please help me with any suggestions to get the package
fgui
to work properly in R Studio and feel free to address the more general issue of effectively loading external packages into R. -
warship almost 10 yearsThe above
capabilities
command works fine for me. I am using MacOSX and looked at the link above. Indeed thetcltk
error I get is very similar to the one posted at the bottom of that link. However, runningsystem("ls -ld /usr/local /usr/local/lib /usr/local/lib/libtcl*")
returns no file permissions errors for me, and performingsudo chmod -R a+rX /usr/local
to double check and rerunning everything over again doesn't fix the issue. Typinglibrary(tcltk)
returns an error for me regardless,Error: package or namespace load failed for ‘tcltk’

Emmanuel-Lin over 6 years@Thomas I know it's an old post, but... I have the error on windows. With R installed by anaconda navigator (dependencie of rpy2)
