Hello everybody!

I've a file with several data six variables, three quantitative and three qualitative, I would like to select a group of data from the file to analyze then, i.e:
my file is like that (but with 6 variables):

Var1   Var2
2       1
5       1
8       1
7       2
3       2
8       2

I want to use only the data where var2 is "1"
2       1
5       1
8       1

Exist a way in R to create a new dataframe with a selection of data from other dataframe?
