[R] Using R "boxplot" function in Excel

[Jessie F]

Hi, I have downloaded the "R-Com and I was able to run "Interactive Graphics 
Demo 2" in excel. However, I couldn't create my own boxplot. Whenever I 
tried to run any code, it always say" Error in loading DLL", even 
"=rput(A1,A2:A20)". Any idea about what's going wrong? A detailed 
explaination about how to use R-Excel tool would be greatly appreciated.
Thanks a lot in advance!
