Description

Merges two character vectors of classpaths for use in creating arguments to initialize the Java Virtual Machine within R. This avoids duplicates.

Usage

mergePath(path, default, collapse=NULL)

Arguments

path

character vector of path elements

default

a character vector containing the default or previous classpath elements

collapse

a character vector used the value of a the collapse argument in a call to paste. If this is non-null, the resulting vector is converted to a single string. This is usually given as ":" on Unix machines and ";" on Windows machines.

Value

A character vector containing the union of the two arguments. If the collapse argument is specified, the elements of the resulting character vector are concatenated/pasted together to yield a single string.
