Re: [R] Naming an object after another object...can it be done?
-Original Message-
x-dat.col
Now, is there a function (or combination of functions) that
will let me assign the character string dat.col to a new
object (called y) without actually typing the characters
dat$col, i.e. just by referring to x?
Yes.
dat - data.frame(col=sample(1:8))
namex - function(x) deparse(substitute(x))
y - namex(dat$col)
y
But wouldn't it be nicer to have the original name follow the data about so you
only needed one object?
The following mild extension of the above will do that,using attributes:
namedvar - function(x) {
attr(x, original.name) - deparse(substitute(x))
x #returns the values as a vector with an attribute original.name
}
#Then
y - namedvar(dat$col)
plot(y, xlab=attr(y, original.name) )

[R] Naming an object after another object...can it be done?
Hello R-helpers, I have run the following line of code: x-dat$col and now I would like to assign names(x) to be dat$col (e.g., a character string equal to the column name that I assigned to x). What I am trying to do is to assign columns in my dataframe to new objects called x and y. Then I will use x and y within a new function to make plots with informative axis labels (e.g., dat$col instead of x. So, for example, I would like to plot (y~x,xlab=names(x)) and have dat$col printed in the x-axis label. I can do this all manually, by typing names(x)- dat$col) but I'd like to do it with non-specific code within my function so I don't have to type the variable names manually each time.

Hi Liu - I have been trying with assign() but it's not working. I don't think that's what I'm looking forany other ideas?

Re: [R] Naming an object after another object...can it be done?
You are thinking that 'names' does something different
than it does. What you seem to be after is the
deparse-substitute idiom:
dat - data.frame(Col1=1:10, Col2=rnorm(10))
myPlotFun - function(x, y) {
plot(y ~ x, xlab=deparse(substitute(x)), ylab=deparse(substitute(y)))
}
myPlotFun(dat$Col1, dat$Col2)

If you want the column names but not

The canonical way to do this is:
myPlotFin(Col2 ~ Col1, data = dat)
I have no idea what the OP wants, but my guess is that the right
answer is: Don't do that.

It is unclear what you intend. It is possible to rename the x-object and it
is possible to name individual elements of a multi-element object named x. It
is furthermore possble to construct an attribute that will remain with x. So,
provide a complete example and it may become clearer.
Also specify whether you are attempting to do this on an object which has been
attached, and if so, then the right answer will be don't use attach().
