[R] Declare BASH Array Using R System Function

[Jeff Newmiller]

You seem confused. You are programming in R, and asking questions about bash on an R mailing list. You seem to need to learn the difference between environment variables and bash variables and how processes acquire and transfer environment variables, which is really an operating system concept and off topic here. Once you do understand this difference, you might be interested in reading the R help file on Sys.setenv().
