Compare matrix with elements in vector by row

I would like to compare values of a matrix to a corresponding vector. The comparison should be performed row-wise. Example matrix: ``` ret TLT VTI 1995-01-20 -0.005649718 -0.004461441 1995-01-23 -0.002840909 0.002560820 1995-01-24 0.000000000 0.000000000 1995-01-25 0.005698006 0.003831418 1995-01-26 0.000000000 0.001908397 ``` VEctor to compare with: ``` compare.vec [1] -0.001 -0.002 ``` What I want is to compare each return element in column 1 of ret to -0.001 and find which one is smaller than -0.001. Vice versa for the second column, comparing it to -0.002 and finding the elements in VTI volumn that are less than that. I tried subset, but it seems its not for a vector but a number. Will I need to loop column for column? Thanks,
