我正在尝试使用lattice
和latticeExtra
软件包来组合两个点图,但是发现x轴上的数据组在组合图中重叠。这是一个可重现的示例:
首先,我创建2个可再现的数据集并将其融化,以使它们变长而不是变宽:
require(lattice)
df1 <- data.frame(Treatment = rep(c("B", "C"), each = 6),
LocB = sample(1:100, 12),
LocC = sample(1:100, 12))
dftwo <- data.frame(Treatment = rep(c("A"), each = 6),
LocA = sample(1:100, 6))
dat.reprod1 <- melt(df1, id.vars = 'Treatment')
dat.reprod2 <- melt(dftwo, id.vars = 'Treatment')
然后为每个数据集创建一个点图:
dotreprod1 <- dotplot(value ~ Treatment, data = dat.reprod1,
par.strip.text = list(cex = 3),
cex = 2)
dotreprod2 <- dotplot(value ~ Treatment, data = dat.reprod2,
par.strip.text = list(cex = 3), col = "orange",
cex = 2)
然后我将它们组合起来,为dotreprod2添加一个新的Y轴:
require(latticeExtra)
doubleYScale(dotreprod1, dotreprod2, add.ylab2 = TRUE, use.style = F)
不幸的是,组合图的x轴上没有用于“ A”的空间,因此橙色点与蓝色点重叠。是否可以在X轴上创建空间,以使“ A”,“ B”和“ C”彼此相邻并且点不重叠?
答案 0 :(得分:1)
在两个单独的图中,将x变量指定为factor
与合并数据的levels
,然后设置drop.unused.levels = FALSE
dotreprod1 <- dotplot(value ~ factor(Treatment, levels = LETTERS[1:3]),
data = dat.reprod1,
drop.unused.levels = FALSE)
dotreprod2 <- dotplot(value ~ factor(Treatment, levels = LETTERS[1:3]),
data = dat.reprod2,
col = "orange",
drop.unused.levels = FALSE)
doubleYScale(dotreprod1, dotreprod2, add.ylab2 = TRUE, use.style = FALSE)
