Connect to DSS via the JVM.
Usage
dss_require(
dss_home = getOption("dss.home"),
message_level = getOption("dss.messagelevel"),
monolith = getOption("dss.monolith"),
quietly = TRUE
)
dss_connect(
dss_home = getOption("dss.home"),
message_level = getOption("dss.messagelevel"),
monolith = getOption("dss.monolith"),
quietly = FALSE
)
Arguments
- dss_home
The path to the HEC-DSS install folder.
- message_level
An integer specifying the DSS message level.
Default is 2L. Use 1L to suppress all messages from DSS.
- monolith
If TRUE, connect to HEC-Monolith libraries.
- quietly
If TRUE, suppress warnings regarding the JVM.
Details
both dss_connect() and dss_require() configure the JVM
to use the HEC-DSS Java library. dss_require() is designed for
use inside other packages; it returns FALSE and gives a
warning (rather than an error as dss_connect() does)
if the HEC-DSS Java library cannot be loaded correctly.
Java Virtual Machine Parameters
When working with very large DSS files, you may need to initialize
the Java Virtual Machine (JVM) with a larger heap size. For more
information see the help vignette:
