calculating the distance of a list of coordinates to a reference coordinate using R

Question

I have an xlsx file which has 200 restaurants and 1 warehouse location with their coordinates in latitude and longitude. I want to calculate the distance from the warehouse to the restaurants using R. And rank them from shortes to longes in km. example table:

title: resturants with location 
name           latitude           longitude 
resturant1     23.646466          90.656566     
resturant2     23.786464          90.254577
resturant3     23.586464          90.789646
resturant4     23.452166          90.656989
x
x
200.....      ..........          .........

table2: warehouse location 
name          latitude             longitude 
warehouse     23.654654           90.7854555

from the above table, I want to calculate the distance from the warehouse to the restaurants using R. And rank them from shorts to longes in km.
