How to generate table output of t-test
Hi, Given test <- matrix(c(1, 1,2,2), 2,2) t <- apply(test, 1, t.test) How can I obtain a table of p-values, confidence interval etc, instead of [[1]] One Sample t-test data: newX[, i] t = 3, df = 1, p-value = 0.2048 alternative hypothesis: true mean is not equal to 0 95 percent confidence interval: -4.853102 7.853102 sample estimates: mean of x 1.5 [[2]]

checkboxes with a has_many :through relation
...my has_many relationship using the post values of these checkboxes. Essentially, I want to populate the relationship table which will create the correct join values in my model. Here is my check_box_tag code: <%= check_box_tag("@current_job[target_list_ids][]", tlist.DataSetID, @current_job.target_lists.include?(tlist)) %> So, in this example, tlist is an element of another array that I''m starting with to give me the list of choices. But what I want is to assign these choices into the "target_lists" collection of my...

Is there a way to have 'comment' keep a list?
Hello all, I recently discovered the "comment" command. I see it can only hold a vector of characters. Is there a way (or an alternative), to make it possible to have it keep a list? (for example, to keep different pieces of information like date of creation, information of each variable and so on) The closest solution I can think of is using 'names' on the vector, like this:

Can I define a object array in R?
Here is my problem, 100 decision trees were built(similar to random forest) and I want to replace some of them by new trees. How can I define a tree array including 100 trees, i.e. t[100], and every t[n] is an "C5.0" object, such that when a new tree comes, i can do n<-10 t[n]<-C5.0(...) -- View this message in context:

Replacing HDD in x4500
The vendor wanted to come in and replace an HDD in the 2nd X4500, as it was "constantly busy", and since our x4500 has always died miserably in the past when a HDD dies, they wanted to replace it before the HDD actually died. The usual was done, HDD replaced, resilvering started and ran for about 50 minutes. Then the system hung, same as always, all ZFS related commands would just

[PATCH 0 of 6 RESEND v2] blktap3/sring: shared ring between tapdisk and the front-end
This patch series introduces the shared ring used by the front-end to pass request descriptors to tapdisk, as well as responses from tapdisk to the front-end. Requests from this ring end up in tapdisk''s standard request queue. When the tapback daemon detects that the front-end tries to connect to the back-end, it spawns a tapdisk and tells it to connect to the shared ring. The shared
