consider nested list data rectangular. mylst1 <- list( "system" = list( "subjectid" = c(101,102,103), "procedureid" = c(202,202,203) ), "demographics" = list( "demo_age" = c(12,22,32), "demo_gender" = c(1,0,1) ), "items" = list( "n" = list( "n001" = c(1,2,3), "n002" = c(3,2,1) ), "e" = list( "e001" = c(1,2,3), "e002" = c(3,2,1) ) ) ) since nested lists awkward work with, let's create data frame: mydf <- data.frame(mylst1) so far good, can perform operations on mydf . let's assume filtered observations. problem need return same nested list structure required web application want send data to, data of course looks this: > str(mydf) 'data.frame': 3 obs. of 8 variables: $ system.subjectid : num 101 102 103 $ system.procedureid
