Alternatives:

congeneric <- scan(textConnection("0.610251 0.615278 0.583581 0.560295
0.501325 0.639512 0.701607 0.544963
0.589746 0.648588 0.608216 0.582599
0.625204 0.523065 0.627593 0.621433
0.733730 0.498495 0.748673 0.591025
0.578333 0.564807 0.652199 0.579333"), sep=" ")
# you would use scan with the filename in which the data is, rather  
than the textConnection. That's just for the purpose of the  
demonstration here.

# possible outputs
congeneric[1:20]

as.list(congeneric[1:20])

for (i in 1:20) {
	cat(congeneric[i],"\n")
}
