R rbind multiple dataframes with names stored in a vector/list

Question

I have a list that references the names of multiple dataframes

df_list

[[1]]
[1] "df_1"

[[2]]
[1] "df_2"

....

[[10]]
[10] "df_10"

How can I run the rbind command referencing df_list so I don't have to reference every one of the 10 names.

all_df <- rbind(df_list)

Instead of

all_df <- rbind(df_1,df_2,df_3,df_4,df_5,df_6,df_7,df_8,df_9,df_10)

Do either of all_df <- do.call(rbind, all_df) or all_df <- lapply(all_df, rbind) work with your data? — jared_mamrot

No, do.call creates a df with one column and the names of the dfs, the other crashes. "object 'df_list' of mode 'function' was not found" — EGM8686

Something like this may work.

Example data: a list with the name of the iris data frame, twice.

df_list<- list("iris", "iris")
df_list

[[1]]
[1] "iris"

[[2]]
[1] "iris"

Then use as.name to convert the strings to the variable names:

all_df <- do.call(rbind, lapply(df_list, as.name))
nrow(df)

[1] 300
