Not sure what is your question, but you can specify your own column prefix for columns of each merged object with named arguments of cbind
:
data('cars')
cars2=cbind(DataSet1=cars, DataSet2=cars)
head(cars2)
# DataSet1.speed DataSet1.dist DataSet2.speed DataSet2.dist
# 1 4 2 4 2
# 2 4 10 4 10
# 3 7 4 7 4
# 4 7 22 7 22
# 5 8 16 8 16
# 6 9 10 9 10
solved R: cbind dataframes with common column names
