[R] Random assignment

[John Haart]

Dear List,

I am doing some simulation in R and need basic help! 

I have a list of animal families for which i know the number of species in each family.

I am working under the assumption that a species has a 7.48% chance of being at risk. 

I want to simulate the number of species expected to be at risk under a random binomial distribution with 10,000 randomizations. 

I am relatively knew to this field and would greatly appreciate a "idiot-proof" response, I.e how should the data be entered into R? I was thinking of using read.table, header = T, where the table has F = Family Name, and SP = Number of species in that family?
