[R] beginner questions: objects and scripts
hi, I got some questions on using R, 1. How do I check and edit definition of an object? for example, x - 1:100 then after a while I want to check how x is defined. list(x) or whatever functions I know only list its content, but I want to see its definition, without scrolling up and down, and edit it like fixing a function. 2. How to save my work in current session as a nice script? again, I want to save objects as they are defined, not numbers, other than copy / paste. I tried dump(), etc. In another word, how do you work with R?

You can use history() to see the past history of commands, but there's no automatic way to find the command that produced x. 2.

hi,
I got some questions on using R,
1. How do I check and edit definition of an object?
for example,
x - 1:100
You should'nt really redefine assignment, but something like
- - function(xyz4, value) {
v - deparse(substitute(value))
xname - deparse(substitute(xyz4))
res - value
comment(res) - v
assign(xname, value=res, inherits=TRUE)
}
and then
-(x, abs(sin(3*pi/2)))
x
[1] 1
comment(x)
[1] abs(sin(3 * pi/2))
You could even redefine - to be -, but don't
Probably better to use the history mechanism.
Kjetil
then after a while I want to check how x is defined.
list(x) or whatever functions I know only list its
content, but I want to see its definition, without
scrolling up and down, and edit it like fixing a
function.
2. How to save my work in current session as a nice
script?
again, I want to save objects as they are defined, not
numbers, other than copy / paste. I tried dump(), etc.
In another word, how do you work with R?
Thanks,
Terry
