[R] coef(summary) and plyr

[moleps]

correction...

Col and rows were mixed up and loop only worked when rows were less than or equal to number of columns....

//M


test<-function(a){
	coef(summary(a))->lo
a<-colnames(lo)
b<-rownames(lo)
c<-length(a)
e<-character(0)
r<-NULL
for (x in (1:length(b))){
	d<-rep(paste(a[1:c],b[x],sep=" "))
	e<-paste(c(e,d))
	t<-lo[x,]
	r<-c(r,t)
	names(r)<-e
	}
	return(r)
}
