Hi Samarvir, Assuming that you want to generate a separate data frame for each value of "Name",
# name of initial data frame is ssdf for(nameval in unique(ssdf$Name)) assign(nameval,ssdf[ssdf$Name==nameval,]) This will produce as many data frames as there are unique values of ssdf$Name, each named by the values it contains.
