Merging multiple data frames in R is anything but straightforward and usually involves confusing loop structures.
multiMerge elegantly avoids such bewildering code chunks by envoking
Reduce upon a list of data frames. The function also features a set of auxiliary parameters that are passed on to
merge. Note that the code is mainly taken from a related blog post in StackOverflow.
## sample data set.seed(10) ls_df <- list(data.frame(a = 1:10, b = 1:10), data.frame(a = 5:14, c = 11:20), data.frame(a = sample(20, 10), d = runif(10))) ## merge data frames in one go merge(ls_df, by = "a", all = TRUE)
