Description
Usage
Arguments
Details
Description
Provides a function simular to merge in Stata to merge data from two data.frames.
Usage
1
ut.merge(mergeParam, db1, db2, entries1, entries2)
Arguments
mergeParam
A vector of column names to use to merge data
db1, db2
The data.frames to merge
entries1, entries2
1 or "m" to tell it whether to do 1:1, 1:m or m:1 matching between databases
Details
Merges 1:1, 1:M or M:1. M:M merging is not supported because this makes unfounded assumptions about the ordering of varaibles. It is better to specify an additional mergeParam column to merge with to explicitely asign M:M matches.
Returns a column named merged denoting 1 for db1, 2 for db2 and 3 for row found in both. Note this will overwrite previous merge columns if they exist.
