Dear R users,
Suppose I have a 4*5 data frame like this:
Date x1 x2 x3 x4
1/1/2004 100 22 12 34
2/1/2004 33 -22 33 12
3/1/2004 12 12 -11 5
4/1/2004 1 223 22 1
Now I want to get a correlation matrix for this dataset excluding column-1
and column-3 i.e. I want to get a correlation matrix for variables x1, x3,
x4. I know that if this dataframe has only three columns containing x1, x3
and x4 instead of five columns then I can use "cor" function. If anyone give
me any code for doing this I will be very grateful
Thanks,
Arun
