Hi all,
I wish to merge 24 .csv files, each having a common identifier-column
("Name") and do two things:
1. Retrieve the common one's. [Analogy: while merging 2-dataframes, similar
to using: merge (.... ,by="Name", all=FALSE) ]
2. Retrieve all, i.e., the union of the rows of 24 files. [again, somthing
like: merge (.... ,by="Name", all=TRUE) ]
On the web, I could see a few ways people seem to merge more than 2
dataframes.
I tried to use library (reshape), but it didn't bring any result:
file_list <- list.files()
m <- merge_all (file_list, by="Name")
Any help would be appreciated.
Thank you.
regards,
Chintanu
