...ds, Please can anyone help me with an easier solution of doing the below mentioned work. Suppose i have a dataset like this:--- i1 i2 i3 i4 i5 1 7 13 1 2 2 8 14 2 2 3 9 15 3 3 4 10 16 4 4 5 11 17 5 5 6 12 18 6 7 *i1,i2,i3,i4,i5 are my items.I am able to find all possible pairs i.e Say this dataframe is "item_pairs" **i1,i2 **i1,i3 **i1,i4 i1,i5 **i2,i1 **i2,i3 i2,i4 i2,i5 **i3,i1 **i3,i2 **i3,i4 **i3,i5 **i4,i1 **i4,i2 **i4,i3 i4,i5 i5,i1 i5,i2 i5,i3 i5,i4 Pairs like (i1,i1) or (i2,i2) are not required.Now pair (i1,i2) is same as pair (i2,i1) .How can i chop...

Hi, All, I have an n by m matrix with each entry between 1 and 15000. I want to know the frequency of each pair in 1:15000 that occur together in rows. So for example, if the matrix is 2 5 1 6 1 7 8 2 3 7 6 2 9 8 5 7 Pair (2,6) (un-ordered) occurs together in rows 1 and 3. I want to return the value 2 for this pair as well as that for all pairs. Is there a fast way to do this avoiding loops? Loops take too l...

Hi all, In the next release of R (4.4) the option to obtain a paired t.test with the formula interface for "long" data has been removed: t.test(x ~ group, paired = TRUE) # now results in an error. Exploring how one might obtain a paired t.test, there seems to be some inconsistency between the formula and default interfaces as well as within the formula...

Hello! I''m trying to move to rails from traditional web app. As Rails has some conventions about table schema, I met some obstacles. Questions. 1. This is a sort of general question. Do you make a code table for things like the following? Activity Status Codes 01001: Open 01002: Pending 01003: Delayed 01004: Cancelled 01005: Closed (The first 2 digits are code category.) Would you

There's a funny inconsistency in how t.test handles paired=T or paired=F. If x and y parameters are lists, paired=F works, but paired=T doesn't. > lg=read.csv("my.csv") > a = subset(lg, condition=="a")["score"] > b = subset(lg, condition=="b")["score"] > t.test(a,b) > t.test(a,b, paire...

If there are many character variables,and I want to get the mosaic plot of every pair of each variable,how to do then? If the variables are numeric, I can use pairs to get paired scatter plot. But as to the character variables, how to get the "paired mosaic plot"? Many thanks. -- QQ: 1733768559 At 2015-02-07 17:04:26,"Jim Lemon" <drjimlemon at gm...

...y difficult in themselves, however they will be very time consuming (Plus I think R will be extremely useful and this is another excuse to learn how to program). I have a vector of 20 values x <- c(20,18, 45, 16, 47, 47, 15, 26, 14,14,12,16,35,27,18,94,16,26,26,30) 1. I want to select random pairs from this data set but do it without replacement exhaustively I know i can select random pairs without replacement using sample(N,n,replace=F) However i am wondering if there is any way to get 10 random pairs from this data set without repeating any of the data points that is to say if i got a (...

Hi guys, I''m new so be gentle :-) How do I put the following into a method inside a model.... select distinct(pairing_id), description from pairings_stories, pairings where pairing_id = pairings.id order by description I basically want to have a @pairlist = Pairing.UniqueBookList line in a controller. Just not sure how to wire up this method in the model. And do I use find_by_sql or is there a nice rai...

Hello, I would like to know if there's a way of setting the callee-saved register list inside getCalleeSavedRegs() to make the PEI pass save/restore only one half of a register pair if the other half is not being used, instead of saving the whole pair. Here is an example of what I try to explain to make things more clear: Suppose this situation where we have a register file of 8bit regs, and that you can form regpairs by joining two adjacent regs. Pairs are pseudo regs that a...

Hello, Writing to share some things I've found about wilcox.test() that seem a a bit inconsistent. 1.

r175088 attempted to fix gcc inline asm compatibility with 64-bit operands by forcing these into even/odd register pairs the same way gcc always allocates such values. While the fix appears to work as such, it is not always activated when required. The patch makes the assumption that any inline asm statement relying on the even/odd allocation will make use of the %Hn syntax to reference the high (odd) register. H...

Hello, some months ago i wrote to the mailing list asking some questions about register pairing, i've been experimenting several things with the help i got back then. Some background first: this issue is for a backend for an 8bit microcontroller with only 8bit regs, however it has a few 16bit instructions that only work with fixed register pairs, so it doesnt allow all combinations of...
