Hi,
I am struggling to create a 2 by 2 multiple graphs in one page. I used
par(mfrow=c(2,2)) to divide the screen into 4. In each screen I draw a pie
chart (They are all same).
For example, my data is like this
Concentration value
A1 69
A2 8
G1 51
G2 1
G3 68
G4 1
M 17
A1, A2... is different levels of the variable called concentration. Folllowing
are their values. I uesd the R code below:
colors <- c("orange","red","purple","pink","blue","yellow","green")
lbls <- round(value/sum(value)*100,1)
lbls <- paste(lbls,"%",sep="")
postscript(file="H:/test.eps", height = 8, width = 8,onefile = FALSE, paper =
"special")
par(mfrow=c(2,2),mar=c(0,0,0,0))
pie(value,labels=lbls,col=colors,radius=0.5)
box(bty="o",col = 'black')
leg <- paste(concentration,lbls,sep=", ")
legend(-1,0.85,leg,cex=0.8,fill=colors)
par(mfrow=c(2,2),mar=c(0,0,0,0))
pie(value,labels=lbls,col=colors,radius=0.5)
box(bty="o",col = 'black')
leg <- paste(concentration,lbls,sep=", ")
legend(-1,0.85,leg,cex=0.8,fill=colors)
par(mfrow=c(2,2),mar=c(0,0,0,0))
pie(value,labels=lbls,col=colors,radius=0.5)
box(bty="o",col = 'black')
leg <- paste(concentration,lbls,sep=", ")
legend(-1,0.85,leg,cex=0.8,fill=colors)
par(mfrow=c(2,2),mar=c(0,0,0,0))
pie(value,labels=lbls,col=colors,radius=0.5)
box(bty="o",col = 'black')
leg <- paste(concentration,lbls,sep=", ")
legend(-1,0.85,leg,cex=0.8,fill=colors)
dev.off()
My question is How do I remove the outside frame. It seems that Box() can only
generate four sided boders. Or is there any way that I can draw the inner
border without using box().
Another question is how can I align the text in the legend? You can see when I
concatenate the concentration level and the percentage, it looks unclear. Is it
possible that percentage can be right aligned?
I am not sure if you can generate the same figure as mine using the above code,
so I attached my graph in case you can't get it. Thank you very much.
