gtable axis names

[schloerke]

Hi,

I heavily depend upon the names of the gtable objects for GGally. With the current master branch of ggplot2, I am getting strange axis gtable names.

qplot(1:10, 21:30, geom = "point") %>% ggplot_build() %>% ggplot_gtable()
# TableGrob (10 x 7) "layout": 17 grobs
#     z         cells       name                                    grob
#1   0 ( 1-10, 1- 7) background        rect[plot.background..rect.4769]
#2   5 ( 5- 5, 3- 3)     spacer                          zeroGrob[NULL]
#3   7 ( 6- 6, 3- 3)     axis-t    absoluteGrob[GRID.absoluteGrob.4764]
#4   3 ( 7- 7, 3- 3)     spacer                          zeroGrob[NULL]
#5   6 ( 5- 5, 4- 4)     axis-l                          zeroGrob[NULL]
#6   1 ( 6- 6, 4- 4)      panel               gTree[panel-1.gTree.4744]
#7   9 ( 7- 7, 4- 4)     axis-r    absoluteGrob[GRID.absoluteGrob.4757]
#8   4 ( 5- 5, 5- 5)     spacer                          zeroGrob[NULL]
#9   8 ( 6- 6, 5- 5)     axis-b                          zeroGrob[NULL]
#10  2 ( 7- 7, 5- 5)     spacer                          zeroGrob[NULL]
#11 10 ( 4- 4, 4- 4)     xlab-t                          zeroGrob[NULL]
#12 11 ( 8- 8, 4- 4)     xlab-b titleGrob[axis.title.x..titleGrob.4747]
#13 12 ( 6- 6, 2- 2)     ylab-l titleGrob[axis.title.y..titleGrob.4750]
#14 13 ( 6- 6, 6- 6)     ylab-r                          zeroGrob[NULL]
#15 14 ( 3- 3, 4- 4)   subtitle  zeroGrob[plot.subtitle..zeroGrob.4766]
#16 15 ( 2- 2, 4- 4)      title     zeroGrob[plot.title..zeroGrob.4765]
#17 16 ( 9- 9, 4- 4)    caption   zeroGrob[plot.caption..zeroGrob.4767]

axis-l is being called axis-t. axis-b is being called axis-r.

If these could be switched back, that'd be great.

Thank you!

The layout and facet ting has been changed and along with that has come support for freely positioning of axis on either side. Because of this there is now axis-l, -r, -t, and -b, though some of them might be zeroGrobs depending on the plot settings. axis-l is still axis-l as before...

[schloerke]

I like the update, but axis-l is a zeroGrob when it shouldn't be in the example above. And axis-t is a non-zeroGrob when it shouldn't be.

Oh - thanks for that catch. That is me failing to convert a matrix to a vector in my head... Will be fixed!

Thanks

thank you!
