I got two .RData file e.g data.2005.RData & data.2006.RData I would like to combine these two different data set and make single RData file. in both file there are some NULL files are also available and I would like to clear this NULL files also. $ : NULL $ : NULL $ : num [1:43285, 1:8] -21.1 -21.1 -24.9 -24.9 -24.9 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : NULL .. ..$ : chr [1:8] "latitude" "longitude" "time" "ch4" ... $ : num [1:44730, 1:8] 5.74 5.74 5.74 -21.06 -21.06 ... ..- attr(*, "dimnames")=List of 2 .. ..$ : NULL .. ..$ : chr [1:8] "latitude" "longitude" "time" "ch4" ... I never worked with RData files, so it will be very nice if somebody can help me to do this operation. -- View this message in context: http://r.789695.n4.nabble.com/add-data-from-RData-file-tp4453981p4453981.html Sent from the R help mailing list archive at Nabble.com.
You can use load() to load them both, if they do not have objects with identical names, then save() to make a new RData file. I'm not clear on what you mean by a NULL file, though. If you know which objects you want to get rid of, you can do that with rm().

HI Sarah, thanks for reply
your method works
what I did
load (" data.2005")
load ( "data.2006")
then
data.new<- c( data.2005, data.2006) or we can save it as a new .RData also.
The NULL files I can remove by selecting particular file number
e.g data.new<- c( data.2005[1:3], data.2006[4:6])
cheers
Uday

You have removed the context of your original question ( and PLEASE stop doing that despite the fact that the Nabble interface leads to to think that the rest of us see it) .... but I seem to remember that you had the same number of columns, so: data.new <- cbind ( data.2005, data.2006 ) save(data.new, file="data.new.RData")> > > The NULL files I can remove by selecting particular file number > e.g data.new<- c( data.2005[1:3], data.2006[4:6]) >-- David Winsemius, MD West Hartford, CT
