'Use object names as list names in R

Of course I could name the objects in my list all manually like this:

    #create dfs
    df1<-data.frame(a=sample(1:50,10),b=sample(1:50,10),c=sample(1:50,10))
    df2<-data.frame(a=sample(1:50,9),b=sample(1:50,9),c=sample(1:50,9))
    df3<-data.frame(a=sample(1:50,8),b=sample(1:50,8),c=sample(1:50,8))

    #make them a list
    list.1<-list(df1=df1,df2=df2,df3=df3)

But it makes a lot of work if I have let's say 50 objects with long names. So is there any way to automate this and make the names inside the list the same as the outside objects?



Solution 1:[1]

If you just want to name a list with names from the environment that share something, in this case 'df':

names(list.1) <- grep("df",ls(),value=TRUE)

If you want to push your environment into a list:

list.1 <- globalenv()
list.1 <- as.list(list.1) 

To reverse the process see ?list2env
