Dear Rajesh,
A quick reply to your questions concerning the diagram package
To use different colors per arrow : just define arr.col as a
matrix or a data.frame, and give the color number or name to each arrow:
To use numbers:
M <- matrix(nrow=4,ncol=4,data=0)
M[2,1]<-1 ;M[4,2]<-2;M[3,4]<-3;M[1,3]<-4
pp<-plotmat(M,pos=c(1,2,1),curve=0.2,name=letters[1:4],lwd=1,box.lwd=2,
cex.txt=0.8,arr.type="triangle",box.size=0.1,box.type="rect",
box.prop=0.5,arr.len=0.6,arr.col=M)
To use color names:
arr.col <- as.data.frame(M)
arr.col[2,1]<-"red"
arr.col[4,2]<-"black"
arr.col[3,4]<-"darkgreen"
arr.col[1,3]<-"orange"
pp<-plotmat(M,pos=c(1,2,1),curve=0.2,name=letters[1:4],lwd=1,box.lwd=2,
cex.txt=0.8,arr.type="triangle",box.size=0.1,box.type="rect",
box.prop=0.5, arr.len=0.8,arr.col=arr.col)
