Colleagues ---------------------------------- System info: Version 1.2.3 (2001-04-26) on NT ESS v. 5.1.18 using emacs ver. 20.4 ---------------------------------- This message is a follow up to a previous enquiry where Patrick Connolly and Brian Ripley both provided helpful suggestions. I want to be able to access objects in another subdirectory than that where I start R. The startup directory (\\biomass spectrum) currently has no objects in it. The other directory (\\opc) has lots of objects. I need to see these, so I tried attaching the .Rdata in \\opc\\R-src. Patrick suggested that it was called _RData in windows, but it does seem to be called .RData.
It is indeed .RData (although Windows will match .Rdata too).
getwd()
[1] "h:\\DATA\\nov99_TAN9913\\biomass spectrum"
objects()
character(0)
setwd("h:\\DATA\\nov99_TAN9913\\opc")
NULL
getwd()
[1] "h:\\DATA\\nov99_TAN9913\\opc"
objects()
character(0)
attach("h:\\DATA\\nov99_TAN9913\\opc\\R-src\\.RData")
objects()
character(0)
You need to either load() the objects, or to attach the .RData file.
In the latter case the objects are available, but not in the user's
workspace. So (without changing the working directory)
attach("h:\\DATA\\nov99_TAN9913\\opc\\R-src\\.RData")
ls(2)
should show you the objects, and they are in the search path as
search()
will show.
