Error in unit(...) with example about ggally HOT 6 CLOSED

I've also tried this with all combinations of ggplot2 0.8.9/0.9.1 and GGally 0.3.2/0.3.1 with the same result

from ggally.

The problem is in the function, ggally_diagAxis(). With iris$Petal.Width, the minimum gridline (x = 0) is actually outside the range of the plot (0.076, 2.524), so when the function tries to use geom_text() to plot the labels on that gridline, it throws an error because the coordinates are outside of the plotting area. ggally_diagAxis() is going to need to be fixed to check for this, and then either extend the plotting area (not great, because then the ranges of the other plots in that row and column would need to be changed) or plot the labels on the next gridline (probably a better option).

Nice catch!

Mo,

This is fixed, and a new version of GGally 0.3.3, is on its way to CRAN now.

cheers,
Di

ggpairs(iris[,3:5])

[1] FALSE
Error in unit(x, default.units) : 'x' and 'units' must have length > 0

It works OK with ggpairs(iris[,1:3]), however

I'm using ggplot2_0.9.1 and GGally_0.3.2

Works great now, thanks!

With the latest ggally installed from git, I am getting a similar error

Error in unit(tic_pos.c, "mm") : 'x' and 'units' must have length > 0

when I try the following code:

ggpairs(iris[,3:5], color='Petal.Width')

from ggally.
