I want to use littler (i.e. "r -i ") to run an R script so I can
set up a clickable icon for a program which uses package staplr.
Actually to use staplr to consolidate two files and remove some unwanted
pages before printout.
A minimal example program is FailBill.R, which has the single line
library("staplr")
staplr is installed, as is rJava. System is Linux Mint 22.1 Xia,
and I had to install default-jre and default-jdk to get rJava
installed. Same error came up in a virtual Linux Mint 22 Wilma,
as I thought recent upgrade to Mint might be the problem.
Starting R and then doing
source("FailBill.R")
works fine.
But in a terminal
r -i FailBill.R
gives
Error: package or namespace load failed for ‘staplr’:
.onLoad failed in loadNamespace() for 'staplr', details:
call: NULL
error: .onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object
'/home/john/R/x86_64-pc-linux-gnu-library/4.4/rJava/libs/rJava.so':
libjvm.so: cannot open shared object file: No such file or directory
Almost certainly some setting/pointer is incorrect, but I've yet to find it,
and see a
lot of posts about rJava, offering plenty of confusion.
Suggestions welcome. Note that the program is interactive, and RScript or
similar
charge ahead and ignore the interactive dialogs that use package svDialogs in
the
program I'm trying to develop. Since I can run in R or RStudio by starting them
and
then source()ing, the situation is not critical, but it would be good to work
out
what is failing.
