Usage

load_filtered(file, envir = parent.frame(), ..., exclude = NULL)

Arguments

file, envir, ...	These arguments have the same meaning as in load().
exclude	Character vector of variable names not to load.

Examples

x <- 5
y <- 3
datafile <- tempfile(fileext = ".rda")
# Only saves y, not x
save.image(datafile)
# Set new values which can be overridden by loading the old ones.
x <- 10
y <- 10
load_filtered(datafile, exclude = "x")
# x is still 10, but y is now 3 again
mget(c("x", "y"))
