I hope this article "how to merge multiple datasets with different column numbers in r language" can help you solve the problem.

Q: multiple datasets with inconsistent column numbers and column names, how to merge by row and then retain the variable union of all files?

A: try using the rbind.fill function!

When data sets are merged by column, the connection mode can be determined according to the merge series functions of merge or dplyr function package to meet the requirements of data merging.

However, rbind, which is often used in line-by-line merging, has a lot of restrictions. It is found that the rbind.fill function of plyr package can better solve this problem.
