printing all htest class members

Hello,
I've posted a question about this subject yesterday, but since there
was no
R code to comment,
no one did.
I'm trying to have the print method for class 'htest' print some extra
information common in some test, like the time series linearity
related
tests. Many of them have an 'order' parameter, representing a lag or
embedding dimension, and it would be a nice feature to pass a vector
of
orders and have all corresponding tests run.
It's easy to do this, but the print method doesn't print those extra
values.
Here the code goes:
#Some values from the McLeod-Li test, with x <- rnorm(100)
res <- data.frame(ord=2:4, df=ord, Q=c(0.0129, 0.049, 0.0684),
p=c(0.9936, 0.9972, 0.9994))
attach(res)
nr <- nrow(res)
My problem reading this is that you are using the attach function which generally confuses discussions and then you are not actually creating any object with a class of htest. Print methods are dispatched by class value.
# print.htest prints everything but 'all.orders' # but when it's named 'null.value' it works and it's easier to make # it work, all what's needed is 'null.value=res', whithout the need # for a second 'structure()'
You seem to be transcribing a conversation inside your head. Most of the four lines above has no connection to what you typed earlier.
structure(
This does nothing. No object is created.
list(statistic=c(Q=Q[1]),
p.value=p[1],
parameter=c(df=df[1]),
alternative="It doesn't print 'all.orders' and I find 'null.value'
misleading",
method="Test the 'print.htest' method using McLeod-Li test values.",
data.name=deparse(substitute(x)),
all.orders=structure(
list(order=ord, df=df, Q=Q, p.value=p),
.Names=c("order", "df", "Q", "p.value"),
row.names=c(NA,-nr),
class="data.frame"
)
),
.Names=c("statistic","p.value","parameter","alternative",
"method","data.name","all.orders"),
class="htest"
)
Is there a way to have 'all.orders' printed by 'print.htest' ?
The problem is NOT the return values, at least the time wasn't wasted,
I can use them for whatever I'll do next.
If not, anyone has any suggestions?
Yes. Give the code you are actually using!
