[R] saving a 'get' object in R

[David Stevens]

R community,

Apologies if this has been answered. The concept I'm looking for is to 
save() an object retrieved using get() for an object
that resulted from using assign. Something like

save(get(foo),file=paste(foo,'rData',sep=''))

where assign(foo,obj) creates an object named foo with the contents of 
obj assigned. For example, if

x <- data.frame(v1=c(1,2,3,4),v2=c('1','2','3','4'))
foo = 'my.x'
assign(foo,x)
# (... then modify foo as needed)
save(get(foo),file=paste(foo,'.rData',sep=''))

# though this generates " in save(get(foo), file = paste(foo, ".rData", 
sep = "")) :
object ‘get(foo)’ not found", whereas

get(foo)

at the command prompt yields the contents of my.x

There's a concept I'm missing here. Can anyone help?

Regards

David Stevens
