Faciliate Use of save and load to Remote Directories

These functions are slightly enhanced versions of save and load that allow a target directory to be specified using options(LoadPath="pathname"). If the LoadPath option is not set, the current working directory is used.

Usage

# options(LoadPath='mypath')
Save(object, name=deparse(substitute(object)), compress=TRUE)
Load(object)

Arguments

object: the name of an object, usually a data frame. It must not be quoted.
name: an optional name to assign to the object and file name prefix, if the argument name is not used
compress: see save. Default is TRUE which corresponds to gzip.

Details

Save creates a temporary version of the object under the name given by the user, so that save will internalize this name. Then subsequent Load or load will cause an object of the original name to be created in the global environment. The name of the R data file is assumed to be the name of the object (or the value of name) appended with ".rda".

Examples

if (FALSE) { # \dontrun{
d <- data.frame(x=1:3, y=11:13)
options(LoadPath='../data/rda')
Save(d)   # creates ../data/rda/d.rda
Load(d)   # reads   ../data/rda/d.rda
Save(d, 'D')   # creates object D and saves it in .../D.rda
} # }
