I know that this has been covered before, but I could not find it.
I have a list of data and I want to select a subset based on a
condition.
A simple example:
data =
{{0.39501, 10}, {1.65689, 20}, {2.40239, 30}, {3.27252, 40}, {4.41738,
50}}
I want to select only the pairs for which the first element of each
pair is greater than or equal to 2.0 and less than 4.0 In this case
the final result would be
{{2.40239, 30}, {3.27252, 40}}
In reality the list is several hundred pairs.
Thanks
Adam
