r - tableGrob : set the height and width of a grid. 表

Question

我正在尝试制作一个功能，该功能将为我提供一个可用于 indesign、插画或inkscape 的绘图。在尝试这样做时，我有两个无法解决的问题。

1)设置我的情节(或只是grobTable)的宽度和高度:
我得到的输出非常小，当在 illustrator 中放大它时，字体会跟随并变大。因此我想用手动定义的宽度和高度来绘制图。

2) 有时标题、注释和行名会“错位”(有关详细信息，请参阅图 1 和图 2 之间的区别)。当行名很短时会发生这种情况。

library(gridExtra)
library(ggplot2)

data(diamonds)

c <- table(x, y)
s <- as.character(sum(c))

j <- prop.table(c,1)

# Plot it 
kryds.row(diamonds$color, diamonds$cut, titel="title", note="note") # plot 1
kryds.row(diamonds$cut, diamonds$color, titel="title", note="note") # plot 2


# Problems
#1: The title, note and the j in the row.text is very badly placed in plot 1 but not   plot 2
#2 I cannot set the width and height of my table

我还没有清理我的代码，所以请随意!

Answer 1

gridExtra::tableGrob 的当前版本不允许您设置宽度/高度。但是，您可以尝试不同的 (experimental)使用 gtable 从头构建的 tableGrob 版本。

#library(devtools)
#install_github("tablegrob", "baptiste")
require(tablegrob)

d <- iris[sample(seq.int(nrow(iris)), 6),]

grid.newpage()
pushViewport(viewport(height=0.8,width=0.9))
g2 <- tableGrob(d, rows=NULL,
                widths=unit(1,"null"), heights=unit(1/(nrow(d)),"npc"))
grid.draw(g2)
grid.roundrect(y=unit(0,"line"), height=unit(1,"npc") +unit(1,"lines"),
               just="bottom", r=unit(0.05, "snpc"))

编辑 (08/2015):您现在可以编辑宽度/高度，因为 grid.table 现在基于 gtable。
