Hi Dan, No, I hadn't thought of that and it WORKS!
I was hoping there'd be such a simple solution. I have new respect for the power of {} w/in R.
Many thanks!

Gilchrist Sent: Tuesday, August 26, 2008 6:03 PM To: r-help@r-project.org Subject: [R] switch() usage Hello, I am wondering if it is possible to run separate lines of code within switch() as one can do in most languages. For example, I'd like to have switch execute a few lines of code based on the value passed to it. For example,index = 1 switch(index, command 1; command 2; command 3, #execute if index = 1 command 4; command 5; command 6, #execute if index = 2 command 7.... #execute if index = 3 )However, if I try this syntax, I get an error about an unexpected ';'. I've tried wrapping the commands in () but that doesn't help either. Is there a way to do this without having to write separate functions for each of the switch possibilities. Thanks. MikeMike, Did you try wrapping the series of commands in braces {}: switch(index, {command 1; command 2; command 3}, #execute if index = 1 {command 4; command 5; command 6}, #execute if index = 2 {command 7.... } #execute if index = 3 ) Hope this is helpful, Dan Daniel J.
