[R-sig-Debian] Problem installing tkrplot package on Ubuntu 20.04

[Chris Evans]

I hope this is the correct list, I _think_ you stretch to Ubuntu as well as Debian (recent posts seem to say so!)

I tried to update packages on my fallback Windows machine and got a message saying "tk.h" was missing.  I reinstalled Rtools: same.  

That's for another message somewhere but, perhaps pride before a fall, I thought "Ha, I bet it works fine in Linux" ... and it doesn't,
well, not for me!  I tried this:

> install.packages("tkrplot")

The downloaded source packages are in
	‘/tmp/RtmpOWOdyG/downloaded_packages’
Warning message:

OK. So I searched and found this (https://stat.ethz.ch/pipermail/r-sig-debian/2018-September/002956.html):

Still too difficult / laborious. Next time remember to do

   apt-cache searck tkrplot      # or any other search term

which would have lead you to

   r-cran-tkrplot

which implies

   sudo apt install r-cran-tkrplot

is all you need. No need for the ballast of two -dev packages, no need to
locally compile.  There is a reason I packaged this maybe 15 years ago ...

Fair point!  So ...

chris using chris-Aether2:~/Rupdate$ sudo apt-get install r-cran-tkrplot

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies.
 r-cran-tkrplot : Depends: r-api-3.5
E: Unable to correct problems, you have held broken packages.

Aha, but apt-check and other things all say I don't have held or broken packages and I think r-api-3.5 is for R 3.5 whereas I'm on 4.0.3 (courtesy
of the amazing work that people here do to package R for Debian and Ubuntu: eternal thanks!)

So I've hit the outer edge of my IT competences and thought I should post here before doing anything more.  As I say, R is 4.0.3 and Ubuntu is 
updated this more 20.04.

TIA,

Chris
