Dear community, I'm working with the data.frame attached ( http://r.789695.n4.nabble.com/file/n4122926/df1.xls df1.xls ), let's call it df1. I typed: df1<- read.xls("C:/... dir .../df1.xls",colNames= TRUE, rowNames= TRUE)
Then I splited randomly df1 using splitdf function (http://gettinggeneticsdone.blogspot.com/2011/03/splitting- dataset-revisited-keeping.html) 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 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?
