使用 grid.arrange 截断标题
Title getting cut off using grid.arrange
在@baptiste this answer 的大力帮助下,我构建了一个快速绘制 table 的函数。
plotTable<-function(data, title=NULL, footnote=NULL, fontsize=9, plotIt=TRUE, show.rownames=TRUE){
# Generic method to plot tabular data
# Built the base table with/without row names
if(show.rownames){
table <- tableGrob(data, theme=ttheme_default(
core=list(fg_params=list(fontsize=fontsize)),
colhead=list(fg_params=list(fontsize=fontsize)),
rowhead=list(fg_params=list(fontsize=fontsize))))
} else{
table <- tableGrob(data, theme=ttheme_default(
core=list(fg_params=list(fontsize=fontsize)),
colhead=list(fg_params=list(fontsize=fontsize)),
rowhead=list(fg_params=list(fontsize=fontsize))), rows=NULL)
}
# Set the padding
padding <- unit(0.5,"line")
# Add the title if it's not NULL
if(!is.null(title)){
title.grob <- textGrob(title, gp=gpar(fontsize=fontsize+3))
table <- gtable_add_rows(table, heights = grobHeight(title.grob) + padding, pos = 0)
table <- gtable_add_grob(table, list(title.grob), t=1, l=1, r=ncol(table))
}
# Add the footnote if it's not NULL
if(!is.null(footnote)){
footnote.grob <- textGrob(footnote, x=0, hjust=0, gp=gpar(fontsize=fontsize, fontface="italic"))
table <- gtable_add_rows(table, heights = grobHeight(footnote.grob)+ padding)
table <- gtable_add_grob(table, list(footnote.grob), t=nrow(table), l=1, r=ncol(table))
}
# Either plot it or return the grob
if(plotIt) grid.arrange(table) else return(table)
}
但有时我的标题比实际标题长 table,而且它被截断了。
libs <- c("data.table", "grid", "gridExtra", "gtable")
lapply(libs, library, character.only = TRUE)
mytable <- data.table(x=c(1,2,3), y=c(3,2,1))
plotTable(mytable, title="Hello World")
我该如何解决这个问题?
您可以手动设置 table 宽度,但您需要决定应该扩展哪些列以及扩展多少。我想重新分配宽度的合理方法是为每列添加相同的边距,这样总的 space 就可以解释标题所需的额外空间。
library(gridExtra)
d <- head(iris[,1:2])
table <- tableGrob(d, rows=NULL)
library(grid)
library(gtable)
title <- textGrob("my long title goes here",gp=gpar(fontsize=30))
padding <- unit(1,"line")
table <- gtable_add_rows(table,
heights = grobHeight(title) + padding,
pos = 0)
table <- gtable_add_grob(table, title,
t=1, l=1,
r=ncol(table))
# check whether the table width is smaller than the title width
missed <- convertWidth(sum(table$widths), "in", valueOnly = TRUE) -
convertWidth(grobWidth(title), "in", valueOnly = TRUE)
if(missed < 0 ) # need to do something about it
table$widths <- table$widths + unit(abs(missed)/ncol(table), "in")
grid.newpage()
grid.draw(table)
如果您不想调整单元格的大小,另一个选项是关闭裁剪,
table$layout$clip <- "off"
