comparing the names and options of two similar meta data

[str_guru]

I have two similar meta data of approx. 1000 records and more than 500 columns . and I want to check the consistency between two data frame. now i want to create a new data frame for which it would show all column names of df1 in first row and same with columns names of df2 in second row and also their option in column 3 and 4 respectively. and then mutate new columns to show TRUE or FALSE if column names and their options are matching.

basically i have to check if column names in df1 is excact with df 2 and if options in all columns of df1 is exactly matching with df2

df1 <- data.frame(ID =c("DEV2962","KTN2252","ANA2719","ITI2624","DEV2698","HRT2921",NA,"KTN2624","ANA2548","ITI2535","DEV2732","HRT2837","ERV2951","KTN2542","ANA2813","ITI2210"),
                  city=c("del","mum","nav","pun","bang","chen","triv","vish","del","mum","bang","vish","bhop","kol","noi","gurg"),
                  Name= c("dev,akash","singh,rahul","abbas,salman","lal,ram","singh,nkunj","garg,prabal","ali,sanu","singh,kunal","tomar,lakhan","thakur,praveen","ali,sarman","khan,zuber","singh,giriraj","sharma,lokesh","pawar,pooja","sharma,nikita"),
                  gender =c("m","f","m","f","m","m","m","m","m","m","m","f","m","f","m","m"))

df2 <- data.frame(ID =c("DEV2962","KTN2152","ANA2719","ITs2624","DEV2698","HRT2921",NA,"KTN2624","ANA2548","ITI2535","DEV2732","HRT2837","ERV2951","KTN2542","ANA2813","ITI2210"),
                  city=c("del","MUm"," nav","pun","bang","chen"," ddgy ","vish","del","mum","bang","vish","bhol","nhus","huay","gurg"),
                  Name= c("dev","singh,rahul","abbas,salman","lal,ram","singh,nkunj","huna,ghalak","khan,fhalt","singh,kunal","tomar,lakhan","thakur,praveen","ali,sarman","khan,zuber","singh,giriraj","sharma,lokesh","pawar,pooja","sharma,nikita"),
                  gender =c("m","f","m","f","m","m","m","male","m","male","m","f","m","f","m","m"))


df <- select(df1,matches("^[A-Z]"))
comp <- do.call(rbind, lapply(df[, 4:ncol(df)], function(option) as.data.frame(table(option)))) 
comp$variable <- gsub("[.](.*)","", rownames(comp)) 
rownames(comp) <- NULL
comp <- comp[, c(3,1,2)] 
comp <- comp[order(-comp$Freq), ]

I am unable to attach the file but i have showed the pic below the required output should look like.

The output should be look like .

Hi @str_guru,
Using full_join() on your two dataframes allows you to line them up based on "ID" and then check each of the other column pairs to see if they are the same. In addition, it allows you to check if all the chosen column pairs are matching. I realize this is not the exact output you requested but it may get you started.
