Dear community,

How to use plotRLE() to plot multiple figures on same page and also only one legend, one x-axis and y-axis title, like this

I can use the codes below to put them in same plot, but not condensed as above.

par(mfrow = c(3,1))
plotRLE(data_ruv, outline=FALSE, col= rle_col, main="RUV_sizefactor", names=NULL, ylim=c(-4, 4))
plotRLE(data_nsolver_ori, outline=FALSE, col= rle_col, main="nsolver_ori", names=NULL, ylim=c(-4, 4))

Where did that first plot come from? The code used to make that may be available.

Anyway, making a plot like that is, in my experience, an iterative process that requires liberal use of the par help page. You could for instance try adjusting par()$mar. For example

> par(mfrow = c(3,1), mar = par()$mar - c(3,0,3,0))
> plot(1:10)
> plot(1:10)
> plot(1:10)

Is closer to what you want. But then you need space at the bottom for the legend, if you want one, and you need to read ?legend to see the placement arguments, etc.
