Hi,

I have a list that looks like the following:

data = {{"westhumber", 0.037`}, {"westhumber", 0.034`}, {"westhumber",
0.037`}, {"westhumber", 0.076`}, {"westhumber", 
0.059`}, {"eldermills", 1.08`}, {"eldermills", 
1.01`}, {"eldermills", 1.22`}, {"coldcreek", 
0.818`}, {"coldcreek", 0.716`}, {"deasthumber", 
0.091`}, {"deasthumber", 0.255`}, {"deasthumber", 
0.235`}, {"deasthumber", 2.18`}, {"deasthumber", 1.7`}};

Now how to extract the sub-lists from the main list as the following :

list1 = {{"westhumber", 0.037`}, {"westhumber", 
   0.034`}, {"westhumber", 0.037`}, {"westhumber", 
   0.076`}, {"westhumber", 0.059`}}

list2 = {{"eldermills", 1.08`}, {"eldermills", 1.01`}, {"eldermills", 
   1.22`}}

list3 = {{"coldcreek", 0.818`}, {"coldcreek", 0.716`}}

list4 = {{"deasthumber", 0.255`}, {"deasthumber", 
   0.235`}, {"deasthumber", 2.18`}, {"deasthumber", 1.7`}}

Thank you in advance.
