dd %>% dotplot( segment ~ transit_time, groups = impact, data = .,
pch = 16:17,
cex = 1.8,
scales = list(cex = 1.4),
key = list(points = 16:17) )
produces a graph with no discernible key, but with an asterisk at the
top, above the plotting region.
Same result from
dd %>% dotplot( segment ~ transit_time, groups = impact, data = .,
pch = 16:17,
cex = 1.8,
scales = list(cex = 1.4),
key = list(points = 16:17),
auto.key = TRUE )
dd %>% dotplot( segment ~ transit_time, groups = impact, data = .,
scales = list(cex = 1.4),
par.settings = simpleTheme(pch = 16:17, cex = 1.8),
auto.key = TRUE)
produces the desired result.
Why does key = list(points = 16:17) not work? Below is a MWE:
================================
library(lattice)
library(dplyr)
dd <- structure(list(impact = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L,
2L), levels = c("impaction", "no impaction"), class = "factor"),
segment = structure(c(4L, 2L, 1L, 3L, 4L, 2L, 1L, 3L), levels =
c("left", "right", "rectosigmoid", "total"), class = c("ordered",
"factor" )), transit_time = c(70, 10, 20, 32, 42, 10, 12, 18)), class =
"data.frame", row.names = c(NA, -8L))
dd %>% dotplot( segment ~ transit_time, groups = impact, data = .,
pch = 16:17,
cex = 1.8,
scales = list(cex = 1.4),
key = list(points = 16:17) )
=================================
Thanks.
