Hi,
I am using R 2.2.0 on Mac OS X 10.3.9. But I test the issue also with R
2.2.1 on OS X 10.4 (Tiger)
I have a question regarding the functioning of the history from the
command line.
When I press the 'up-arrow' I call back the last command (everything
ok), let's say that I go back until the level n-5, but when I get down
to return to the empty line, I cannot reach the empty line... The empty
line 'level' show me the content of the line n-4.
example, let's say I did this sequence of command:
> x <- c(1:10)
> mean(x)
[1] 5.5
> sd(x)
[1] 3.027650
> x
[1] 1 2 3 4 5 6 7 8 9 10
>
# If I return to the command 'x <- c(1:10)' and then get down the
bottom line is :
> mean(x)
Well it doesn't work like that under Windows and I guess under Linux.
What is the setting that I should change?
Or where is the error I made...
David
