I'm working with the data.frame attached (
http://r.789695.n4.nabble.com/file/n4122926/df1.xls df1.xls ), let's call it
I typed: df1<- read.xls("C:/... dir .../df1.xls",colNames= TRUE, rowNames=
Then I splited randomly df1 using splitdf function
So now, I have df1 divided in another 2 dataframes: trainset and testset.
(They both have the same row names and column names as df1)
I'd like to change df1$v1 and df1$v2 values in the trainset and testset by
the ones in df2 ( http://r.789695.n4.nabble.com/file/n4122926/df2.xls
How can I explain R to identify in trainset/testset$v1 and $v2 the rownames
and replace the values by the corresponding ones in df2?
Thanks in advance,
