Boxplot from one variable

[anhoej]

Thank you for an excellent package.

I’m struggling with boxplots. When I create a boxplot from a single variable, tinyplot uses sequence numbers on the x-axis. I would expect a boxplot to handle single-variable plots in the same way a histogram does.

library(tinyplot)

# Plot histogram
plt(Nile, type = 'histogram')

# Attemp to plot boxplot from one variable
plt(Nile, type = 'boxplot')

# Make dummy variable for x axis
x <- cut(seq_along(Nile), c(0, 28, 100))

# Plot boxplot from two variables - CORRECT!
plt(Nile ~ x, type = 'boxplot')

Thanks, this is a good point. You can manually work around this by creating a grouping variable x with just a single group. If the levels of that group are empty strings and also x-axis label and ticks are suppressed you can match the output of boxplot(Nile):

boxplot(Nile)
x <- rep("", length(Nile))
tinyplot(x, Nile, xlab = "", xaxt = "a")

I think it would be good to make this the default behavior. However, I don't think that this can be easily accomplished in type_boxplot() but it would be relatively easy in tinyplot.default() when processing the is.null(y) cases. I'll create a PR for this.

Or do you see a better way, Grant @grantmcdermott ?

Thanx! Nice workaround.

Sorry for being late to this, but this should work out-of-the-box in the dev version now thanks to @zeileis's PR in #454.
