Controlling Ticks Repetition.

[g-pacheco]

Hello,

Thanks a lot for the great package. I understand that one can control the label repetition by using repeat.tick.labels. Would it be possible to add a similar option for the ticks themselves?

Best regards, George.

It is not clear to me, what you mean the similar option for ticks actually should do. /Stefan ons. 24. nov. 2021 15.15 skrev George Pacheco ***@***.***>:

Hello @stefanedwards,

Thanks for your quick reply. Say I have the plot below created with this code:

# Creates Manhattan panel ~
Fst_Window <-
  ggplot() +
  geom_line(data = fulldfa, aes(x = gPoint, y = Fst, colour = Pops), linetype = 1, size = .6) +
  facet_rep_grid(CHR ~. , scales = "free", repeat.tick.labels = "left", labeller = labeller(CHR = y_strip_labels)) +
  scale_x_continuous("Genomic Position",
                     breaks = c(5000000, 10000000, 15000000, 20000000, 25000000, 30000000), 
                     labels = c("5Mb", "10Mb", "15Mb", "20Mb", "25Mb", "30Mb"),
                     limits = c(0, 32000000),
                     expand = c(0, 0)) +
  scale_y_continuous("Fst Across Chrmosomes",
                     breaks = c(.1, .3, .5), 
                     labels = c("0.1", "0.3", "0.5"),
                     limits = c(0, .525),
                     expand = c(0, 0)) +
  scale_colour_manual(values = c("#4daf4a", "#9970ab", "#f46d43")) +
  theme(panel.background = element_rect(fill = "#ffffff"),
        panel.border = element_blank(),
        panel.grid.minor = element_blank(),
        axis.line = element_line(colour = "#000000", size = .3),
        axis.title.x = element_text(size = 20, face = "bold", color = "#000000", margin = margin(t = 30, r = 0, b = 0, l = 0)),
        axis.title.y = element_text(size = 20, face = "bold", color = "#000000", margin = margin(t = 0, r = 30, b = 0, l = 0)),
        axis.text = element_text(colour = "#000000", size = 15),
        axis.ticks = element_line(color = "#000000", size = .3),
        strip.background.y = element_rect(colour = "#000000", fill = "#d6d6d6", size = .3),
        strip.text = element_text(colour = "#000000", size = 11.5, face = "bold"),
        legend.position = "top",
        legend.margin = margin(t = 0, b = 0, r = 0, l = 0),
        legend.box.margin = margin(t = 30, b = 25, r = 0, l = 0),
        legend.key = element_rect(fill = NA),
        legend.background =element_blank()) +
  guides(colour = "none", fill = "none")

I would like to have the ticks on the x-axis just once (very first x-axis down), and not on the repeated x-axis lines. So, the option would allow the user to control this behaviour. What do you think?

Thanks again, George.

It seems to me that what you are asking for here is the default behaviour of ggplot2's own `facet_grid`. Or are you looking to have the x-axis (with ticks and labels) at the bottom of the top-most panel? That would be most unorthodox, and outside the scope of what I can do in a reasonable way. You could consider putting the x-axis (with ticks and labels) at the top, with `scale_x_continuous("Genomic Position", position = "top", ...`.

Hej. Sorry for not making myself clear -- thanks for your explanation. I still do not think that what I am looking for is the default behaviour of facet_grid. I was only brave to draw on 3 of them, but I hope you will get the idea. What I would like it to do is to repeat only the x-axis line, and not the x-axis line AND the x-axis ticks. So, the x-axis ticks and labels would appear only once (on the bottom panel ), while the x-axis line would be present in all panels. Does it make more sense now?
