Hi R-help

I have some question.
First I have data in Excle ,then I would like to fit distribution
from this data, how to import this data from excle? What's command?

Thaks for first answer

Second

I learn R program from The Basics of S and S-plus book because it's basic,
and then when I use command is attact(geyser) [follow from book] but I can't 
.
Because it's command only S (i think some command can't use in R???)

Thanks
