Performs automatic argument vectorization, provides default Java exception and warnings handling for XLConnect.
xlcCall(obj, fun, ..., .recycle = TRUE,
.simplify = TRUE, .checkWarnings = TRUE, .withAttributes = FALSE)Result of the specified function by calling it with the vectorized argument list.
XLConnect S4 object (e.g workbook, cellstyle) which
has a slot jobj representing a rJava jobjRef object whose method represented
by the argument fun should be called.
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.
Whether to check for warnings registered on the underlying Java object.
Whether the function being called returns a wrapped Java object with attributes.
If TRUE:
the object will be unwrapped
if option XLConnect.setCustomAttributes is TRUE, the attributes will be processed and set on the resulting R object.

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.
