Hi,
The dparams argument of geom_qq allows to define the parameter of the distribution function using numeric values. However, when one uses facetting or grouping, these values may be different. Is there a way to set group/facet specific values?
require(ggplot2)
#> Loading required package: ggplot2
set.seed(1234)
df <- data.frame(
panel = factor(rep(1:2, each = 100)),
grp = factor(rep(c(2, 3, 1, 4), each = 50)),
x = c(
rlnorm(50, 2, 0.5),
rlnorm(50, 3, 1.5),
rlnorm(50, 1, 0.1),
rlnorm(50, 4, 1)
),
mean = rep(c(2, 3, 1, 4, each = 50)),
sd = rep(c(0.5, 1.5, 0.1, 1), each = 50)
)
ggplot(data = df, aes(sample = x, colour = grp)) +
geom_qq(distribution = qlnorm, dparams = list(mean = 1, sd = 0.5)) +
facet_wrap('panel', scales = 'free')
