/etc/apt/source.list: deb ... cloud.r-project ... bionic-cran35/
R installed just fine.
However, my ubuntu software update would not finish correctly any more. Failed

There are already no copies done for length(unclass(x)) in pqR

When I try to save plots as WMF or EMF pictures specifying small picture size,
e.g.., 3x5 inches, I get a wrong size of the WMF/EMF picture. The plot itself

Hello,
Watch out for operator precedence.

#[1] TRUE
`%~~%` <- function (e1, e2) all.equal(e1, e2)
0.3 %~~% 0.1*3

Now with isTRUE. The problem changes a bit.

Maybe a new Operator could be defined for a fast and easy double
Comparison: `~~`
`~~` <- function (e1, e2) all.equal(e1, e2)
And document it properly.
