Re: [R] Changing sign of columns and values

Hi Hana, I didn't look closely. The simplest rule that I can see is that the letters (nucleotides?) should be swapped if there has been a sign change in the beta value. Therefore: mydf<-read.table(text= "IDnumber OA EA beta 1 C A -0.05 2 GA0.098 3 GT

Re: [R] How to do non-parametric calculations in R

Imagine that it's the year 2022 and you don't know how to look up information about performing a Kruskal-Wallis H test. It would take you longer to join the listserv and then write such a cokamemie email than to open the stats textbook you are supposed to have for the course, much less doing

Re: [R] Changing sign of columns and values

Dear jim thanks for your help! I want to change also the value of OA and EF simultaneously.For instance i am looking the datamydf IDnumber OA EA  beta1     1  A  C  0.0502    2  G  A 0.0983    3  T   G 0.789Best, Hana                  Original message From: Jim Lemon

Re: [R] Changing sign of columns and values

Hi Hana, I think this is what you want: # first read in your example mydf<-read.table(text= "IDnumber OA EA beta 1 C A -0.05 2 GA0.098 3 GT-0.789", header=TRUE,stringsAsFactors=FALSE) # check it mydf IDnumber OA EA beta 11 C A

This is a plain text list. Your html post got mangled (see below). You are more likely to get a useful response if you follow the posting guide (linked below) and post in plain text. Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it."

Re: [R] Interpreting the result of a model with random effects

Looks like the center effect improves overall accuracy while being independent of the other terms. A few things to try Compare coef(model.fix) to fixef(model.rand). Add center as a fixed effect to model .fix Try a conditional logit (clogit from survival) See how consistent the coefficients

[R] Interpreting the result of a model with random effects

Dear R users, I'm analyzing a particular score "y" among several individuals, each of which belongs to a center, a factor with three different levels (3 possible centers). I have treated the "center" as a fixed effect, and as a random term (package lme4): 1) model.fix <- glm(y ~ var.1 + var.2

Re: [R] igraph: layout help

Hello, The code below is a hack. First I create a layout ll, then see that vertex K coordinates are in the layout matrix 2nd row. Now, to multiply K's coordinates by a number d>1 will move the point away from A. Add that value to the K group and plot. ll <- layout_with_kk(my.graph) d <-
