我正在为报告创建几个刻面图.刻面的数量在2到8之间变化.理想情况下,我希望每个刻面的绝对大小(跨越图表)是相同的(例如4x4厘米),以便更容易比较它们(它看起来也更好) ).
那可能吗？
df1 <- structure(list(group1 = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 1L,1L, 1L, 1L, 1L, 1L), .Label = c("S1", "S2"), class = "factor"), group = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L), .Label = c("A", "B", "C", "D", "E"), class = "factor"), value = 1:12), class = "data.frame", row.names = c(NA, -12L), .Names = c("group1", "group", "value"))
df2 <- structure(list(group1 = structure(c(2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L), .Label = c("S1", "S2"), …以下代码用于工作但不再适用.有人知道发生了什么事吗？必须对基础gtable代码进行一些更改.
require(cowplot) # for plot_grid()
require(grid) # for unit_max()
# make two plots
plot.iris <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
geom_point() + facet_grid(. ~ Species) + stat_smooth(method = "lm") +
background_grid(major = 'y', minor = "none") +
panel_border()
plot.mpg <- ggplot(mpg, aes(x = cty, y = hwy, colour = factor(cyl))) +
geom_point(size=2.5)
g.iris <- ggplotGrob(plot.iris) # convert to gtable
g.mpg <- ggplotGrob(plot.mpg) # convert to gtable
iris.widths <- g.iris$widths[1:3] # extract the first three widths,
# corresponding to left margin, y …
