Rotating y axis labels with mosaic plots WITHOUT overlap - r

Question

This question is extremely similar to this one yet from another point of view which has not been responded.
Following the proposed code, I am able to generate mosaic plots and rotate the labels so that they are legible. The problem comes when (it seems) the mosaic() function from vcd package does not recognise the rotation and so it does not adapt the graph to fit the labels, yielding results like the following:
Is there any way to change the margins between the labels and the titles? I would be surprised if I am the first one that has encountered this issue. I am open to using other packages to get mosaic graphs if applicable as well.
Code
aux = structure(c(0L, 0L, 3L, 46L, 107L, 14L, 0L, 0L, 4L, 0L, 0L, 2L,
9L, 0L, 23L, 2L, 1L, 3L, 14L, 1L, 8L, 26L, 6L, 11L, 6L, 1L, 6L,
0L, 1L, 1L, 29L, 10L, 62L, 1L, 3L, 1L, 1L, 3L, 1L), .Dim = c(3L,
13L), .Dimnames = list(abcdefghi = c("Madrid", "Valencia", "Granada"
), jklmnopqr = c("roknbjftxcwl", "mfchldbxuyig", "gtyoxeduijpw",
"akbcefymvsiw", "ucbfxplietqk", "mzeykauprfdh", "piermgawyjht",
"chjvatqbylxo", "merhcogjflbd", "wiyrugvmhjlq", "glszdqmjhkov",
"giowaxrtsknm", "pxucytzvljqw")), class = "table")
library(vcd)
colours = c("brown","darkgreen","darkgrey","orange","darkred","gold","blue","red",
"white","pink","purple","navy","lightblue","green","peachpuff","violet","yellow","yellow4")
aux_names = names(attr(aux,"dimnames"))
mosaic(aux,main=paste(aux_names,collapse=" vs. "),
gp=gpar(fill=matrix(sample(colours,max(nrow(aux),ncol(aux))),1,max(nrow(aux),ncol(aux)))),
pop = FALSE,labeling = labeling_border(rot_labels=c(90,0,0,0),
just_labels=c("left","right")))

Answer 1

This code should do what i think you're after.
mosaic(aux,main=paste(aux_names,collapse=" vs. "),
gp=gpar(fill=matrix(sample(colours,max(nrow(aux),ncol(aux))),1,max(nrow(aux),ncol(aux)))),
pop = FALSE,labeling = labeling_border(rot_labels=c(90,0,0,0),
just_labels=c("left","right"),
offset_varnames = c(8,8,8,8)),
margins = c(10, 10, 10, 10))
