Hi,
Is there a way to incorporate an R object x to a file already containing R objects?
It seems that 'save' is not capable to do this. If I save x to a file containing
previously saved data, then I will lose this data.
See if the following helps:
x <- 2 save(x, file="x.rda") rm(x) attach("x.rda") assign("y", 3, pos=2) ls(2)
[1] "x" "y"
save(list=ls(2), file="x.rda") detach(2) x
Error: Object "x" not found
y
Error: Object "y" not found
attach("x.rda") x
[1] 2
y
[1] 3
ls(2)
[1] "x" "y"
I use the funcion hsv in .Rprofile but it is recognized. Couriously, if I source .Rprofile
when R is already running I do not get any error message.
Not sure what you mean...
He meant that .Rprofile is loaded before package graphics is attached, and therefore hsv() cannot be found.
Attaching the package in .Rprofile or setting a hook should be sufficient.
