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
