[R] Pairwise comparison, TukeyHSD, glht, ANCOVA

Hi, I'm wondering if i can use the function "TukeyHSD" to perform the all pairwise comparisons of a "aov()" model with one factor (e.g., GROUP) and one continuous covariate (e.g., AGE). I did for example: library(multcomp) data('litter', package = 'multcomp') litter.aov <- aov(weight ~ gesttime

Re: [R] Pairwise comparison between columns, logic

Hi Arun, Many thanks for following this through. Based on your earlier suggestion with CEBPA, I also edited the code and now it seems work (I removed the non exiting names). I looked into the current code that you have sent below and I learnt a few more things. So thank you again. Your skills i

Re: [R] Pairwise comparison between columns, logic

Hi, Using the example code without removing CEBPA: gset<- read.table("Names.txt",header=TRUE,stringsAsFactors=FALSE)  temp1<- read.table("Data.txt",header=TRUE,stringsAsFactors=FALSE) lst1<-split(temp1,temp1$Names) mat1<-combn(gset[,1],2) library(plyr) lst2<-lapply(split(mat1,col(mat1)),function(x

Re: [R] Pairwise comparison between columns, logic

Hi Manisha, I didn't run your dataset as I am on the way to college.  But, from the error reported, I think it will be due to some missing combinations in one of the dataset.  For ex. if you run my previous code without removing CEBPA: ie. mat1<- combn(gset[,1],2) lst2<-lapply(split(mat1,col(ma

Re: [R] Pairwise comparison between columns, logic

HI, Not sure about what your expected output would be.  Also 'CEBPA' was not present in the Data.txt. gset<- read.table("Names.txt",header=TRUE,stringsAsFactors=FALSE)  temp1<- read.table("Data.txt",header=TRUE,stringsAsFactors=FALSE) lst1<-split(temp1,temp1$Names) mat1<-combn(gset[-1,1],2) #rem

analysis of variance was signifigant there are a couple of observations that are NA I would like to do a means seperation TukeyHSD or pairwise.t.test how do I deal with the NAs I will provide the data if necessary -- Let's not spend our time and resources thinking about things that are so littl
