Hello,

I have two data frames, X and Y, with two columns each and different numbers
of rows.

# creation of data frame X

Loc1.alleles     <- c(1,5,6,7,8)
Loc1.Freq        <- c(0.35, 0.15, 0.05, 0.10, 0.35)
Loc1             <- cbind( Loc1.alleles,Loc1.Freq)
X            <- data.frame(Loc1)

#creation of data frame Y

Loc2.alleles  <- c(1,4,6,8)
Loc2.Freq     <- c(0.35, 0.35, 0.10, 0.20)
Loc2          <- cbind(Loc2.alleles, Loc2.Freq)
Y             <- data.frame (Loc2)

I would like a flexible way to multiply each element of second column of the
X data frame
by each element of the second column of the Y data frame.

 example of what the operation need to do:  X[1,2]*Y[,2] ;
X[2,2]*Y[,2].............X[4,2]*Y[,2]

I have worked on a variety of "for" loops to get this to work without
success.

The final result should look like a column like this

    "all_X[,2] * all_Y[,2]"
        0.1225
        0.1225
        0.0350
        0.0700
        0.0525
        0.0525
        0.0150
        0.0300
        0.0175
        0.0175
        0.0050
        0.0100
        0.0350
        0.0100
        0.0200
        0.1225
        0.1225
        0.0350
        0.0700

any help would be greatly appreciated
