Hi,
I have two scripts, one creates a data structure (a list of data frames
+ some attributes) and saves it via saveRDS.
The second script reads the RDS file (outside of any function) and
data <- readRDS (name)
works, but
data <<- readRDS (name)
creates the error
Error: cannot change value of locked binding for 'data'
Any idea what goes wrong?
"data <<-" looks for an existing object named data in a parent
environment and changes it. But the existing object is in the utils
namespace, and you're not allowed to change things there.
