xlcCall: Automatic argument vectorization, default Java exception and warnings handling for XLConnect
Description
Performs automatic argument vectorization, provides default Java
exception and warnings handling for XLConnect.Usage
xlcCall(obj, fun, ..., SIMPLIFY = TRUE)
Arguments
obj
XLConnect S4 object (e.g workbook, cellstyle) which
has a slot jobj representing a rJava jobjRef object whose method represe fun
Name of function to be called.
...
Arguments to the function to be called. These arguments will be automatically vectorized using mapply. SIMPLIFY
Argument to mapply. Attempt to reduce result of function call to a vector or matrix? Value
- Result of the specified function by calling it with the vectorized argument list.
Details
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.
