Wie bekomme ich install.packages von R in einem Dockerfile? - r

Unten ist ein Befehl, der fehlgeschlagen ist, aber Docker behieltgehen. Ich bin mir ziemlich sicher, dass die "Warnung" ("Installation hatte einen Exitcode ungleich Null") nicht als Exitcode ungleich Null an den Aufruf von Rscript übergeben wurde.

Wie bekomme ich das, um den Docker-Build zu stoppen?

Antworten:

Sie können erzwingen, dass Warnungen als Fehler behandelt werden (d. H. Sofortiges "Stoppen") options(warn = 2). Von ?options:

 "warn": sets the handling of warning messages.  If "warn" is
negative all warnings are ignored.  If "warn" is zero (the
default) warnings are stored until the top-level function
returns.  If 10 or fewer warnings were signalled they will be
printed otherwise a message saying how many were signalled.
An object called "last.warning" is created and can be printed
through the function "warnings".  If "warn" is one, warnings
are printed as they occur.  If "warn" is two or larger all
warnings are turned into errors.
