How to combine dataframes based on the names in common in R?

Question

So my data is currently split into 211 dataframes in R and I was wondering if there was a way to combine all of them without having to type out the name of every dataframe. Each dataframe is named in a similar way: starts with "dma" then has the number of the dma it corresponds to (dma1-dma211). Is there a combine/merge function that allows me to select all dataframes that start with "dma" and combine them? All of the dataframes have the same columns and names of columns and I want to combine them vertically. Thanks!!

Answer 1

We can use mget to get the values of the objects that starts with 'dma' followed by digits into a list and then rbind with do.call in base R

out <- do.call(rbind, mget(ls(patterns = '^dma\\d+$')))

Or with tidyverse

library(dplyr)
out <- mget(ls(patterns = '^dma\\d+$')) %>%
          bind_rows
