Install a Custom jvecfor JAR — jvecfor

Copies a custom jvecfor JAR to the user data directory (tools::R_user_dir("jvecfor", "data")). The bundled JAR in inst/java/ is used by default; call jvecfor_setup() only to override it with a custom build. Alternatively, set options(jvecfor.jar = "/path/to/jvecfor.jar") for a session-level override without copying.

Usage

jvecfor_setup(jar_path = NULL)

Arguments

jar_path: Path to the jvecfor JAR. If NULL, auto-searches java/jvecfor/target/jvecfor-*.jar relative to the working directory (works when developing inside the source tree).

Value

Invisibly returns the path to the installed JAR.

Examples

# Show where custom JARs are stored
tools::R_user_dir("jvecfor", "data")
#> [1] "/home/runner/.local/share/R/jvecfor"

# List bundled JARs
dir(system.file("java", package = "jvecfor"), pattern = "*.jar")
#> [1] "jvecfor-1.2.0.jar"
