Error Generated on Importing Empty Sheet about xlsx HOT 3 CLOSED

Please attach a minimal code example which illustrates the issue. 

If you're trying to read a sheet that does not exist in a spreadsheet, I want 
the code to fail not to return NULL.  The sheet is not there.  If the error 
message is not clear about it, I can improve on that.

Here is the code:

res <- read.xlsx("K:/Troubleshoot.xlsx", 1) #works because first sheet contains 
data
res2 <- read.xlsx("K:/Troubleshoot.xlsx", 2) #generates error because sheet is 
empty.  This should return NULL.  This causes my web application to crash

fixed it in trunk.  Now both read.xlsx, read.xlsx2 return NULL when the sheet 
is empty. 

Thanks, 
Adrian
