That is simply not true. There is no mention in help for data of "data"
being a reserved word.
Moreover, if "data" *were* a reserved word " <- " wouldn't work either.
Compare:
data <- 42 # No

Hi,
I have two scripts, one creates a data structure (a list of data frames

The second script reads the RDS file (outside of any function) and
data <- readRDS (name)
works, but
data <<- readRDS (name)
You need to do
help("<-")
for a full explanation but in brief when you do <- it assigns locally
and since it could not find data locally it makes it for you but when
you do <<- it tries its very best to find data somewhere. Since data is
the name of a function which the authors of R have
?data
will show you that data is a reserved word!

Hi,
thanks, using
test <<- readRDS (name)
it worked. But why?

Try calling it something other than data.
