Performs automatic argument vectorization, provides default Java exception and warnings handling for XLConnect.
xlcCall(obj, fun, ..., .recycle = TRUE, .simplify = TRUE)
Name of Java method to be called.
Arguments to the Java method to be called.
If TRUE
(default), arguments passed through … will be automatically vectorized using mapply
and
fun
will be called the appropriate amount of times.
If FALSE
, no vectorization will take place in R and fun
will be called once only. This may be used to implement
vectorization on the Java side.
Only relevant if .recycle = TRUE
. Argument to internal mapply
to set if there should be an attempt to
reduce the result to a vector or matrix.
Result of the specified function by calling it with the vectorized argument list.
This function makes use of mapply
to perform automatic argument vectorization. Non-atomic arguments are
wrapped in a list using wrapList
first. The list of the resulting arguments is then being vectorized
using mapply
before the specified function is being called. The function call is wrapped with
jTryCatch
to catch Java exceptions. Further, any warnings are retrieved from the Java side and are logged
via R's standard warning mechanism.
