Just an FYI, *if* all you're doing is rbind():ing those data frames, then you're better of doing:
df <- do.call(rbind, dfs) than df <- Reduce(rbind, dfs) because the former is faster and more memory efficient: > dfs <- rep(list(iris), times=100) > bench::mark(df <- Reduce(rbind, dfs))[,1:7] # A tibble: 1 x 7 expression min median `itr/sec` mem_alloc `gc/sec` n_itr <bch:expr> <bch:tm> <bch:tm> <dbl> <bch:byt> <dbl> <int> 1 df <- Reduce(rbind, dfs) 65.5ms 68.6ms 13.6 108MB 30.7 8 Warning message: Some expressions had a GC in every iteration; so filtering is disabled. > bench::mark(df <- do.call(rbind, dfs))[,1:7] # A tibble: 1 x 7 expression min median `itr/sec` mem_alloc `gc/sec` n_itr <bch:expr> <bch:tm> <bch:tm> <dbl> <bch:byt> <dbl> <int> 1 df <- do.call(rbind, dfs) 8.67ms 9.47ms 105. 14MB 49.5 34 /Henrik On Fri, Sep 13, 2019 at 5:39 AM <bio...@posteo.de> wrote: > > Thank you for all of your answers.
