Hi again,

As this problem seems to be related to plot.igraph I just open an issue in igraph-github page: https://github.com/igraph/rigraph/issues/69

For now the workaround I am using is to plot only the x-values contained in your xlim range, like below:

library(igraph)

g<-erdos.renyi.game(30,0.4)
x<-1:100;

par(mfrow=c(2,2));
hist(degree(g),main="A");
plot(x[40:90],sin(x[40:90]),type="l",xlab="x",ylab="sin(x)",xlim=c(40,90),main="D")
plot(g,main="C");box();
plot(x[40:90],sin(x[40:90]),type="l",xlab="x",ylab="sin(x)",xlim=c(40,90),main="D")

Best,

Charles

By the way[2]: The problem persists is I use par(mfrow=c(2,2)) instead of layout. Please test with the following code:

library(igraph)

g<-erdos.renyi.game(30,0.4)
x<-1:100;

par(mfrow=c(2,2));
hist(degree(g),main="A");
plot(x,sin(x),type="l",xlab="x",ylab="sin(x)",xlim=c(40,90),main="B")
plot(g,main="C");box();
plot(x,sin(x),type="l",xlab="x",ylab="sin(x)",xlim=c(40,90),main="D")

So, it is one more evidence that the problem should be caused by the igraph.plotting. Any idea?

Best.

Dear all,

I am trying to plot 4 different plots in the same figure using graphics::layout to organize the plots. The code below reproduces more or less what I am doing:

library(igraph)

g<-erdos.renyi.game(30,0.4)
x<-1:100;

m<-rbind(c(1,1,1,2,2,2),c(1,1,1,2,2,2),c(1,1,1,2,2,2),c(3,3,3,4,4,4),c(3,3,3,4,4,4),c(3,3,3,4,4,4));
layout(m);

hist(degree(g),main="A");
plot(x,sin(x),type="l",xlab="x",ylab="sin(x)",xlim=c(10,60),main="B")
plot(g,main="C");box();
plot(x,sin(x),type="l",xlab="x",ylab="sin(x)",xlim=c(10,60),main="D")

My problem is that the curve plotted in "D" (that is exactly the same as in "B") is shown out of the margins. I suppose it is out of margins because I plot a graph right before "D".

Does any of you have any idea if plotting a graph can have any effect in the margins of the next plot? Any clue about how to solve this problem?
