In either case you're wrong with respect to the pairing. :-) Sorry, I am used to the way NEC documents their PBXs and this is what they call it. The Zytrax website documents it like this: Pin: Signal: 1 Rx1 2 Rx2 4 Tx1 5 Tx2 (http://www.zytrax.com/tech/layer_1/cables/tech_rs232.htm - bottom of page) So my question about a "real" T1 cable i...

Hi friends, 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

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?

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 interface. ``` extra.1 <-

Hi, Assuming that your dataset is similar to the one below: set.seed(25) dat1<- data.frame(Algae.Mass=sample(40:50,10,replace=TRUE),Seagrass.Mass=sample(30:70,10,replace=TRUE),Terrestrial.Mass=sample(80:100,10,replace=TRUE),Other.Mass=sample(40:60,10,replace=TRUE),Site.X.Treatment=rep(c("ALA1A","ALA1U"),each=5),stringsAsFactors=FALSE) library(reshape2)

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, paired=TRUE) Error in `[.data.frame`(y, yok)

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 gmail.com>

Hello R users My goal is to use R to write functions for and automate a series of analyses i would like to do on a large data set. The calculations are not very 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,

The following command produces red axis line in a pairs plot: pairs(iris[1:4], main = "Anderson's Iris Data -- 3 species", pch = "+", col = c("red", "green3", "blue")[unclass(iris$Species)]) Trying to fool pairs in the following way produces the same plot as above: pairs(iris[1:4], main = "Anderson's Iris Data -- 3

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 rails/...

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

Hello, Writing to share some things I've found about wilcox.test() that seem a a bit inconsistent. 1. Inf values are not removed if paired=TRUE # returns different results (Inf is removed): wilcox.test(c(1,2,3,4), c(0,9,8,7)) wilcox.test(c(1,2,3,4), c(0,9,8,Inf)) # returns the same result (Inf is left as value with highest rank): wilcox.test(c(1,2,3,4), c(0,9,8,7), paired=TRUE)

...en/odd allocation is skipped. One possible fix, which I have tested, is to look for the specific instructions requiring such a pair (LDRD/STRD and LDREXD/STREXD) in addition to the 'H' modifier. However, there are probably other creative ways in which inline asm might rely on the specific pairing. Thus I believe the safest solution is to always force 64-bit operands into even/odd pairs for any inline asm. In other words, we should probably do something like this (untested): --- a/lib/Target/ARM/ARMISelDAGToDAG.cpp +++ b/lib/Target/ARM/ARMISelDAGToDAG.cpp @@ -3457,19 +3457,6 @@ SDNode *ARM...

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 re...

Hi, I have what I think is some kind of linear programming question. Basically, what I want to figure out is if I have a vector of numbers, > x <- rnorm(10) > x [1] -0.44305959 -0.26707077 0.07121266 0.44123714 -1.10323616 -0.19712807 0.20679494 -0.98629992 0.97191659 -0.77561593 > mean(x) [1] -0.2081249 Using each number only once, I want to find the set of five pairs where

Hi R Helpers, I'm still new to R and i experience many difficulties..I'm using vegan package (R version 2.11) trying to calculate checkerboard units for each species pair of a matrix.
