Hi,
Try:
dat2<-
read.csv("BOlValues.csv",header=TRUE,sep="\t",row.names=1)
dim(dat2)
#[1] 20 28
indx2<-expand.grid(names(dat2),names(dat2),stringsAsFactors=FALSE)
nrow(indx2)
#[1] 784
indx2New<- indx2[indx2[,1]!=indx2[,2],]
nrow(indx2New)
#[1] 756
res2<-sapply(seq_len(nrow(indx2New)),function(i) {x1<- indx2New[i,];
x2<-cbind(dat2[x1[,1]],dat2[x1[,2]]);summary(lm(x2[,1]~x2[,2]))$coef[,4][2]})
#changed here
dat3<- cbind(indx2New,value=res2)
dim(dat3)
#[1] 756?? 3
library(reshape2)
res2New<- dcast(dat3,Var1~Var2,value.var="value")
row.names(res2New)<- res2New[,1]
?res2New<- as.matrix(res2New[,-1])
?dim(res2New)
#[1] 28 28
A.K.
