Some issues:
1) Variable names cannot have spaces. "merged 1" is not valid but "merged_1" is a valid alternative.
2) You need to tell R what to merge by. It looks like you may be using data tables rather than a data frame.
merged <- dataset2[dataset1, on = "id", nomatch = NA]
3) Alternatively: join functions from the dplyr package, cbind(), and rbind() can be used in...

Help merging large datasets in R
Hi guys,
For my MSc. thesis i am using R studio. The goal is for me to merge a couple (6) of relatively large datasets (min of 200.000 and max of 2mil rows). I have now been able to do so, however I think something might be going wrong in my codes.
For reference, i have a dataset 1 (200.000), dataset 2 (600.000), dataset 3 (2mil) and dataset 4 (2mil) merged into one dataset of 4mil, and dataset 5
