#Hello,
#I have three data frames, X,Y and Z with two columns each and different
numbers of rows.
# creation of data frame X
X.alleles <- c(1,5,6,7,8)
X.Freq <- c(0.35, 0.15, 0.05 , 0.10, 0.35)
Loc1 <- cbind( X.alleles,X.Freq)
X <- data.frame(Loc1)
#creation of data frame Y
Y.alleles <- c(1,4,6,8)
Y.Freq <- c(0.35, 0.35, 0.10, 0.20 )
Loc2 <- cbind(Y.alleles, Y.Freq)
Y <- data.frame (Loc2)
# creation of data frame Z
Z.alleles <- c(1,4,5,6,8)
Z.Freq <- c(0.35, 0.35, 0.05, 0.05, 0.20)
Loc3 <- cbind(Z.alleles, Z.Freq)
Z <- data.frame (Loc3)
X
Y
Z
# I want to create a pair wise multiplication for all of the second columns
of my dataframe X,Y and Z
# Here is a way to get two of the data frames to create a pairwise
multiplication.
X.Freq_times_Y.Freq<- matrix(Y[,2] %o% X[,2], ncol=1)
X.Freq_times_Y.Freq
# I would like to create a loop to calculate all possible pairwise
multiplications for the
# second columns of my X,Y, and Z data frames.
# I will be conducting pair wise comparisons for up to 50 different data
frames so I need the code to be
# as flexible as possible
Any help would be greatly appreciated.
Thanks in advance
