[R] help.search warning?

[Dong-hyun Oh]

Dear useRs,

When I executed help.search(), I got nothing other than the following  
warning message.

R> help.search("print")
Error in help.search("print") :
  (converted from warning) removing all entries with invalid multi- 
byte character data

I am using Leopard 10.5.4 and R-2.7.1.

How to solve the above problem?

Best,
Dong-hyun Oh
