[R] extending zoo (or ts) objects
list(...) I would like to extend zoo objects for use in a hydrological application. By that I mean I want to attach various attributes, such as id numbers, coordinates of the observation location, a units specification, etc. I might also want to add to the class attribute (inheriting from zoo) and define some custom methods. I can add attributes() to a zoo object, but the problem is that when I do operations on the object, such as window, `[`, lag etc, the attributes are lost. That makes it awkward to manage. E.g. foo - zoo(1:5, order.by=as.Date(1:5)) attr(foo, location) - c(150, -35) The functions below all return a modified zoo object; test which ones keep the user-specified attributes: attr(foo[1:4], location) NULL attr(window(foo), location) NULL attr(lag(foo), location) NULL attr(na.approx(foo), location) ## this one keeps attributes [1] 150 -35 attr(rollmean(foo, 1), location) NULL attr(aggregate(foo, months, mean), location) NULL I notice that many operations on ts objects have the same behaviour (dropping user-specified attributes). In contrast, subsetting (indexing) a data.frame keeps them, as I had expected. Any ideas for how to manage this?

[R] Getting at what a named object represents in a function...
Hi,
I'm pretty new to R.
I have an object (say a list) and I I have a function that I call on
various columns in that list (excuse terminology if it's wrong/ambiguous).
Imagine its like this (actual values are unimportant) and called mylist:
mylist
AB
15
25
36 48
50
I have a function:
foo = function(param){
#modify list A or B values depending on whether A or B's passsd in (via
'param')
param[someindex]=another_value #doesn't change value in lits$A or
list$B (whichever's been passed in as 'param')
#I want something like:
#if 'param' is list$A then list$A[someindex]=another_value
#else if 'param' is list$B then list$B[some_index] = another_value
}
I then call this function on mylist$A (i.e. foo(mylist$A) and then on
mylist$B (i.e. foo(mylist$B))
so 'param' in function foo is either mylist$A or mylist$B - can I tell
which it is so that when param[someindex] is changed, it's actually
mylist$A or mylist$B that's changed?
If I modify param values in foo(), they're not modified in list...so is
there a way to tell whether param represents list$A or list$B and hence
allow to me to modify those actual values rather than 'param'?
Thanks for help,
Martin

[R] pairs, par(plt)
I'm having some confusion over the coordinate system after using pairs. I'm not interested in the content of the actual pairs plot, although the number of pairs seems to matter a bit. I'm purely interested in knowing where my points will be plotted on the device. However, after using pairs, the par information (omd, fig, plt, and usr) don't reflect what points does. For example: pairs(iris[1:5]) par(xpd = NA) points(0 - 0.01 * 1:100, 0 - 0.01 * 1:100) points(0 - 0.01 * 1:100, 1 + 0.01 * 1:100) points(1 + 0.01 * 1:100, 0 - 0.01 * 1:100) points(1 + 0.01 * 1:100, 1 + 0.01 * 1:100) par(c(omd, fig, plt, usr)) The resulting plot shows that the corners of the are approximately 0.05 user coordinate units from the boundaries of the plot region. According to par, though, there is a margin around the plotting region that is clearly not symmetric and does not correspond to around 0.05 units. If we use pairs(iris[1:2]) and repeat the rest, the corners are now 0.02 user coordinate units. par provides the same information as before. So: 1. How do I figure out where coordinates I give to points will display on the figure? 2. More generally (for my own understanding), why does the par information not do what I expect? Do I have some fundamental misunderstanding of the arrangement of plotting, figure, display, and margin regions within the device? I'm using R 2.5.1, and this behavior occurs on a fresh R console.

Re: [R] Secondary Y axis title
I was curious about the exact same question that John Theal posed - how to get a second y-axis label for a plot of two data series against a common x (in my case, time). I tried two different methods - one in lattice and one in plot. Both times the y-axis on the right side appears but the label does not. Similar to John's comment, it appears that there is not enough room for the label. Gabor mentioned that the plot.zoo examples give a plot like this. When I run that series of examples, #7 appears to be what Gabor was referring to, but even there the label for the right-hand y-axis is missing. Help?

Re: [R] Secondary Y axis title
That's strange.

Re: [R] formatting a list

Hi,
I am new to R and need to read in a file with 19 columns and 7000 rows
and make it into a list of 7000 lists with 19 items each. For a
simpler case of 10 by 10 table I used x -scan(file,
list(0,0,0,0,0,0,0,0,0,0)), perhaps clumsy, but it did the job.
However with the large 19x7000 (which needs to be transposed) I am not
sure how to go about it.
Coudl somebody suggest a way?
dat - as.data.frame( matrix( scan('tmp.txt'), nr=19) )
returns a data.frame which is a list with some added attributes.
or
dat - lapply( readLines('tmp.txt'), function(x) scan(textConnection(x)
) )
Or
char.dat - strsplit( readLines('tmp.txt'), split='[[:blank:]]+')
numeric.dat - lapply( char.dat, as.numeric )
HTH,

Re: [R] Secondary Y axis title
In the zoo example you can control how far it lies from the axis by adjusting the text() command and you can alter the margins using the values for the mai parameter in the par() command. On 10/20/07, John Theal [EMAIL PROTECTED] wrote: I still haven't resolved this problem. However, when I run the plot.zoo example the label appears, it also appears if I enter the commands manually. The problem that persists is that the label has to lie so close to the secondary y axis, that (in my case) it becomes almost indistinguishable from the axis scale labels. If the label is long, then it over-writes some of the scale labeling. I thought it might be do to the way the Quartz window manager handles the figure margins (under Mac OS X), but it looks as though maybe this is not the case.

Re: [R] Secondary Y axis title
The controls for the margin sizes, which set the amount of space allocated for the labels, are the 'mai' numbers in the first 'par' call. The fourth number changed to 0.9 or greater should give you more room like you're looking for. You can use the alternative 'mtext' way of adding the label (it's simpler), which I have used below to make the right label appear the same distance from the axis as the left label (option line = 3). I don't see how to adjust the reading direction of the label to be top-to-bottom with 'mtext', so I guess you'll need the 'text' way of doing it if you want that orientation (although I don't understand the 'usr' positions that define the location). Gabor, do you know how to change the reading direction with 'mtext'? I tried 'srt' and that did not work. library(zoo) set.seed(1) z - zoo(cbind(A = cumsum(rnorm(100)), B = cumsum(rnorm(100, mean = 0.2 par(mai = c(.8, .8, .2, .9)) # Or change '.9' to a larger number for even more room (the units are inches) plot(z[,1], type = l, xlab = X axis label, ylab = colnames(z)[1], lty = 1, lwd = 2) par(new = TRUE) plot(z[,2], type = l, ann = FALSE, yaxt = n, col = blue, lty = 2, lwd = 2) axis(4) legend(x = topleft, bty = n, lty = c(1,2), lwd = c(2,2), col = c(black, blue), legend = paste(colnames(z), c((left y-axis), (right y-axis mtext(colnames(z)[2], 4, line = 3, col = blue) --Dave At 11:42 PM 10/20/2007 +0200, John Theal wrote: I still haven't resolved this problem.

Re: [R] Secondary Y axis title
mtext does not support srt -- use text instead. There is a comment about that in the example although perhaps the wording could be clearer.
