I'm trying to install the package Rcmdr however it has a dependency on tcltk2 whom has a dependency on tcltk but I cannot install tcltk.

My status:

> capabilities()["tcltk"]
tcltk 
FALSE

What I've tried:

install.packages("https://cran.r-project.org/src/contrib/Archive/tcltk/tcltk_0.1-1.tar.gz", type="source", repos=NULL)

Returns:

Installing package into ‘/home/felipeaugustox/R/x86_64-pc-linux-gnu-library/3.6’ (as ‘lib’ is unspecified) trying URL 'https://cran.r-project.org/src/contrib/Archive/tcltk/tcltk_0.1-1.tar.gz' Content type 'application/x-gzip' length 5000 bytes ================================================== downloaded 5000 bytes

ERROR: cannot extract package from ‘/tmp/RtmpH9kH6v/downloaded_packages/tcltk_0.1-1.tar.gz’ Warning in install.packages : installation of package ‘/tmp/RtmpH9kH6v/downloaded_packages/tcltk_0.1-1.tar.gz’ had non-zero exit status

What I also tried:

R CMD INSTALL tcltk_0.1-1.tar.gz

Returns:

ERROR: cannot extract package from ‘tcltk_0.1-1.tar.gz’

My setup:

  • R version 3.6.1
  • Ubuntu 18.06

  • tcltk is a system package. Look up on AskUbuntu how to install it. – IRTFM Jun 23 '20 at 17:39
  • @IRTFM I installed with `sudo apt-get install tcl8.5-dev tk8.5-dev` – Felipe Augusto Jun 23 '20 at 17:46
  • In that case perhaps using a binary install of the R package, making sure that it is matched to R 3.6.x. See https://cran.r-project.org/bin/linux/ubuntu/ – IRTFM Jun 23 '20 at 17:48
  • Isn't that what I tried? `R CMD INSTALL tcltk_0.1-1.tar.gz` – Felipe Augusto Jun 23 '20 at 18:05
  • @user20650 After that: `r-cran-tcltk2 is already the newest version (1.2-11-1.1).` – Felipe Augusto Jun 23 '20 at 18:10
  • I thought the tar.gz packages were source rather than binary. I'm not an expert. I just installed that package from an Rstudio console and see: after snipping the installation messages which did NOT indicate that this needed compilation `"* DONE (tcltk2) The downloaded source packages are in ‘/tmp/RtmpzcDvH5/downloaded_packages’ > library(tcltk2)` Loading required package: tcltk" I'm using Ubuntu 18.04 and R 3.6.1 My suystem reports `$ echo "puts [info tclversion]" | tclsh # 8.6` – IRTFM Jun 24 '20 at 01:16
  • I’m wondering if there is a conflict or confusion about which version of tcl is being accessed by R. Supposedly R ships with tcltk 8.5 – IRTFM Jun 25 '20 at 06:06
  • I read in some place that I needed to "build from source with tcltk installed", but I don't know what it means, since I could achieve what I want without this package I'm gonna stop searching for a solution, but keep the question, for other people with similar problems. – Felipe Augusto Jun 25 '20 at 20:13

  • I installed here, but I receive the same errors when trying to install `tcltk2`: > error: Tcl/Tk support is not available on this system – Felipe Augusto Jun 23 '20 at 17:49
